# OnlineCoinFlips.com — Global Header Development Prompt

Act as a senior WordPress frontend developer, UI/UX designer, accessibility specialist, and vanilla JavaScript engineer.

Create a complete, premium, modern, responsive, accessible, and production-ready global header for **OnlineCoinFlips.com**.

## Project Context

- Website: OnlineCoinFlips.com
- Homepage: https://onlinecoinflips.com/
- Niche: Online coin flipping and heads-or-tails decision-making
- Primary SEO keyword: coin flip online
- CMS: WordPress
- Theme: Divi
- Integration: WP Coder
- Technologies: HTML5, CSS3, Bootstrap-compatible markup, and vanilla JavaScript
- Icons: Boxicons exclusively
- Typography: Inter
- Maximum inner width: 1350px

## Brand System

Use the official palette:

- Navy: `#464B71` — logo area, navigation, text, and primary structure
- Ocean Blue: `#118AB2` — CTA, active links, and interactive accents
- Mint: `#7CD5C7` — active indicators and subtle highlights
- Soft White: `#F2F2ED` — light surfaces and backgrounds
- White may be used for the main header surface

Maintain accessible contrast for all text, buttons, icons, focus states, and active states.

The design concept is:

**“Simple Navigation, Instant Decisions.”**

The result should feel lightweight, polished, approachable, and purpose-built for a coin-flipping utility. Avoid generic corporate styling, oversized gradients, excessive decoration, glowing effects, and distracting animation.

## Header Structure

Build one global header containing:

- Left: linked website logo
- Center: desktop navigation
- Right: primary CTA

Desktop layout:

**Logo | Navigation | CTA**

Vertically center all elements and maintain balanced spacing.

The outer header may span the viewport, but its inner container must have a maximum width of `1350px` with responsive horizontal padding.

Use the unique root wrapper:

`#ocf-global-header`

Do not create multiple header instances.

## Logo

Display the actual website logo using an editable image `src` placeholder. This is the only permitted placeholder.

Requirements:

- Link to `https://onlinecoinflips.com/`
- Alternative text: `OnlineCoinFlips.com`
- Preserve the natural aspect ratio
- Do not stretch or distort the image
- Do not substitute a fictional logo, generic icon, or placeholder text

Recommended limits:

- Desktop width: approximately 190–220px
- Desktop height: approximately 48–55px
- Mobile width: approximately 150–180px

## Navigation

Use this exact order on desktop and mobile:

1. Home
2. Features
3. About
4. Pricing
5. Blog
6. Contact
7. FAQs
8. Flip a Coin CTA

Use these exact destinations:

- Home: `https://onlinecoinflips.com/`
- Features: `https://onlinecoinflips.com/features`
- About: `https://onlinecoinflips.com/about`
- Pricing: `https://onlinecoinflips.com/pricing`
- Blog: `https://onlinecoinflips.com/blog`
- Contact: `https://onlinecoinflips.com/contact`
- FAQs: `https://onlinecoinflips.com/faqs`

Do not add, remove, reorder, or randomly shuffle the links. Do not create dropdown menus.

Desktop navigation should use:

- Inter
- Approximately 14–15px font size
- Medium font weight
- Navy text
- Comfortable spacing
- Subtle hover transitions
- Visible keyboard focus styles
- A restrained underline or bottom indicator for the active page

## Primary CTA

CTA text:

**Flip a Coin**

Destination:

`https://onlinecoinflips.com/`

Place it immediately after FAQs.

Style it with:

- Ocean-blue background
- Accessible contrasting text
- Approximately 10–12px border radius
- Comfortable padding
- Medium or semibold typography
- A valid Boxicons coin icon such as `bx-coin-stack`
- Subtle hover elevation
- Visible keyboard focus
- Restrained transitions

On mobile, place the CTA after FAQs inside the expanded menu and make it prominent and easy to tap.

Do not create another coin-flipping tool or invent an unverified anchor ID.

## Active-Page Detection

Automatically identify the active page with vanilla JavaScript.

Requirements:

- Use `window.location.pathname`
- Normalize trailing slashes
- Handle `/` as the homepage
- Use exact matching for the established navigation paths
- Do not mark Home active on unrelated pages
- Keep Blog active on article pages only when the site’s URL structure reliably identifies them as blog content
- Apply `aria-current="page"` to the active link
- Apply the active state on page load
- Use ocean-blue text plus a mint underline or indicator
- Do not communicate the active state through color alone

## Mobile Navigation

At the responsive breakpoint, replace the desktop menu with:

**Logo | Hamburger button**

Use a real button and Boxicons exclusively:

- Closed icon: `bx-menu`
- Open icon: `bx-x`

The mobile menu must:

1. Open when the toggle is activated.
2. Close when the toggle is activated again.
3. Close when a navigation link is selected.
4. Close when Escape is pressed.
5. Close when the user clicks outside the menu.
6. Close when the viewport returns to desktop width.
7. Avoid duplicate event listeners.
8. Preserve keyboard navigation.
9. Preserve the active-page indicator.
10. Restore focus to the toggle when appropriate.

Provide:

- `aria-label`
- `aria-expanded`
- `aria-controls`
- Visible focus styles
- Correct hidden-state behavior
- No focusable hidden controls
- No keyboard traps

Use a standard disclosure menu unless a modal overlay is genuinely necessary. Do not add focus trapping to a normal disclosure panel.

Use a lightweight fade, slide, or expansion transition and respect `prefers-reduced-motion`.

The mobile menu should use:

- White or soft-white background
- Navy navigation text
- Ocean-blue active states
- Subtle dividers
- Comfortable vertical spacing
- Rounded panel corners where appropriate
- CTA after FAQs
- Reliable stacking above page content

## Responsive Behavior

Large desktop, 1200px and wider:

- Logo on the left
- Seven centered navigation links
- CTA on the right

Small desktop and tablet:

- Switch to the hamburger layout when the complete navigation no longer fits comfortably
- Do not compress all seven links into an overcrowded row

Mobile, 320px–767px:

- Left-aligned logo
- Right-aligned hamburger
- Collapsible navigation
- Prominent mobile CTA
- No horizontal overflow
- No clipped or overlapping content
- Comfortable touch targets

Verify behavior at:

- 320px
- 375px
- 414px
- 768px
- 1024px
- 1280px
- 1440px

## Header Positioning

The header must work naturally within WordPress and Divi.

Do not introduce a second sticky-header system when Divi already controls sticky positioning.

If custom sticky behavior is implemented:

- Scope it to `#ocf-global-header`
- Respect the WordPress admin bar
- Keep header height stable
- Prevent page-content overlap and layout shifts
- Avoid unnecessary scroll listeners

A subtle shadow or surface adjustment after scrolling is acceptable if implemented efficiently. Do not automatically hide the header while scrolling.

## WordPress, Divi, and WP Coder Isolation

Suggested classes include:

- `ocf-header-inner`
- `ocf-header-logo`
- `ocf-header-nav`
- `ocf-header-menu`
- `ocf-header-link`
- `ocf-header-cta`
- `ocf-header-toggle`
- `ocf-header-mobile`
- `ocf-header-active`

Scope every custom selector beneath:

`#ocf-global-header`

Never use unscoped selectors targeting:

- `body`
- `html`
- `header`
- `nav`
- `a`
- `button`
- `img`
- `.container`
- `.row`
- `.btn`
- `.menu`
- `.et_pb_menu`
- `.et-l`
- `.mobile_menu_bar`

Do not override Divi’s global typography, navigation, buttons, responsive rules, or default WordPress elements.

Use an isolated IIFE or equivalent JavaScript pattern:

- No global variables
- No unnecessary dependencies
- No duplicate listeners
- No unsafe global event behavior
- Scope DOM queries to `#ocf-global-header`
- Handle missing elements safely
- Prevent repeated initialization
- Do not interfere with Divi scripts
- Do not use `document.currentScript` or `previousElementSibling` to locate the root
- Do not override `window.dispatch` or `Event.prototype`

Place the header in the WordPress/Divi global header area. Do not insert it as an additional page-level header. If the default Divi header remains enabled, configure the theme layout so only the intended global header appears. Do not hide Divi or WordPress elements through unsafe global CSS.

## Icons and Typography

Use Boxicons exclusively. Do not use Font Awesome, Bootstrap Icons, inline icon substitutes, or another icon library.

Do not load Boxicons more than once if the site already provides it.

Use Inter throughout the component without duplicating an existing font load.

Recommended dimensions:

- Desktop navigation: 14–15px
- CTA: 14–15px
- Mobile links: 16px
- Desktop header height: approximately 76–88px
- Mobile header height: approximately 64–72px

Allow the exact dimensions to adapt to the logo and available space.

## Accessibility

Ensure:

- Semantic header and navigation markup
- Accessible logo link
- Meaningful logo alternative text
- Keyboard-operable controls
- Correct ARIA attributes
- Correct `aria-current="page"` handling
- Visible focus indicators
- Accessible contrast
- Escape-key support
- Focus restoration
- Reduced-motion support
- No keyboard traps
- No hidden focusable navigation when the mobile menu is closed
- Mouse, touch, and keyboard compatibility

## Performance

Keep the component lightweight:

- Use Flexbox or CSS Grid
- Use vanilla JavaScript only
- Avoid duplicate Bootstrap, Boxicons, and font loads
- Avoid unnecessary DOM manipulation
- Avoid unnecessary scroll listeners
- Use efficient mobile transitions
- Prevent layout shifts
- Reserve appropriate logo dimensions
- Do not create multiple header instances

## Content Restrictions

Do not include:

- Placeholder navigation links
- Broken or invented URLs
- Fictional social links
- Reviews or testimonials
- Ratings
- Trust badges
- Fabricated statistics or claims
- Dropdown menus
- Dummy buttons
- Nonfunctional controls
- Duplicate headers
- Lorem ipsum
- Unfinished content
- Placeholders other than the editable logo image source

## Required Verification

Before delivery, verify that:

1. The logo exists, has an editable source, and links to the homepage.
2. Navigation order is exactly Home, Features, About, Pricing, Blog, Contact, FAQs.
3. The Flip a Coin CTA appears immediately after FAQs.

15. Inter and the official colors are used.
16. The inner maximum width is 1350px.
17. All CSS is isolated beneath `#ocf-global-header`.
18. JavaScript is isolated and safely initialized.
19. No global Divi or WordPress elements are modified.
20. The component does not duplicate the Divi header.
21. The layout works from 320px through large desktops.
22. No horizontal overflow occurs.
23. Reduced-motion preferences are respected.
24. The implementation is accessible, lightweight, polished, and publication-ready.

## Delivery Requirements

The implementation must use:

- The official brand colors
- Inter
- An editable logo image source
- The exact required navigation order and URLs
- The Flip a Coin CTA immediately after FAQs
- A fully functional mobile disclosure menu
- Automatic active-page highlighting

## Creative direction

Use the concept:

**“The Simplicity of a Coin Toss, Reimagined for Everyday Decisions.”**

The page should feel modern, minimal, trustworthy, approachable, lightweight, informative, and specifically designed for OnlineCoinFlips.com.

Use restrained coin-inspired visual elements, including circular outlines, concentric rings, balanced halves, heads-and-tails motifs, dotted trajectories, and simple probability diagrams. Favor premium editorial compositions over repetitive card grids.

Do not use stock photographs, fictional team portraits, fabricated company stories, testimonials, statistics, badges, or a second coin-flipping tool.

## Required page structure

Build the following eleven sections in this exact order.

### 1. About Introduction

Eyebrow:

**ABOUT ONLINECOINFLIPS.COM**

H1:

**About OnlineCoinFlips.com**

Copy:

“OnlineCoinFlips.com brings the familiar heads-or-tails coin toss into an online experience, making it convenient to settle simple choices, decide who goes first, and explore the idea of chance.”

“Sometimes, two options are equally acceptable, and choosing between them doesn't need to be complicated. A coin flip offers a familiar way to make that decision.”

Include a primary CTA:

- Label: Flip a Coin Online
- URL: https://onlinecoinflips.com/

Use a premium two-column hero on desktop, with editorial copy on the left and a large static coin-inspired CSS or inline-SVG illustration on the right. Stack the copy above the illustration on mobile. The illustration must be decorative and hidden appropriately from assistive technology.

### 2. What Is OnlineCoinFlips.com?

H2:

**What Is OnlineCoinFlips.com?**

Copy:

“OnlineCoinFlips.com is a website built around a simple concept: flipping a coin online to obtain a heads-or-tails result.

A coin toss is commonly used when two choices are available and neither requires a complicated decision-making process. Instead of searching for a physical coin, visitors can use an online alternative.

The website is intended for everyday decisions, casual games, friendly tiebreakers, and educational examples involving chance and probability.”

H3:

**A Familiar Idea in a Digital Format**

Copy:

“Flipping a coin is a widely recognized method for choosing between two possibilities. By assigning one option to heads and the other to tails, people can use the result to settle a low-stakes decision.”

Use an editorial two-column layout. Include a static visual panel split into balanced HEADS and TAILS halves. Do not make the panel interactive.

Naturally incorporate “coin flip online,” “online coin flip,” “heads or tails,” and “flip a coin online.”

### 3. Our Purpose

H2:

**Why OnlineCoinFlips.com Exists**

Introduction:

“The purpose of OnlineCoinFlips.com is straightforward: make the familiar coin-toss method available online and provide useful information about when and how it can be used.”

Present three purpose statements with large numbered markers, subtle dividers, and Boxicons:

1. **Make Simple Choices Easier** — `bx-git-branch`  
   “Provide a straightforward way to approach casual decisions involving two acceptable options.”

2. **Keep the Experience Approachable** — `bx-check-circle`  
   “Focus on the familiar heads-or-tails concept so visitors can understand how to use a coin toss without complicated instructions.”

3. **Make Probability More Understandable** — `bx-book-open`  
   “Help visitors connect everyday coin tossing with basic ideas about chance, probability, and independent outcomes.”

Present these as the website’s purpose, not as historical corporate mission statements.

### 4. What Makes OnlineCoinFlips.com Useful?

H2:

**A Simple Tool for Everyday Choices**

Description:

“An online coin flip is useful when a decision has two clear possibilities and everyone involved is comfortable letting chance determine the outcome.”

Use an asymmetric feature composition with one prominent visual panel and four compact descriptions:

- **Heads-or-Tails Simplicity** — `bx-coin-stack`  
  “Assign one choice to heads and the other to tails, then use the coin-flipping tool to obtain a result.”

- **Convenient Online Access** — `bx-devices`  
  “Use an online alternative when you don't have a physical coin available.”

- **Useful for Casual Games** — `bx-joystick`  
  “Choose who goes first, select a side, or resolve an informal tiebreaker.”

- **Helpful for Learning** — `bx-book`  
  “Use coin tossing as a familiar example when learning about probability and independent events.”

Do not claim unsupported functions such as saved results, advanced customization, multiple modes, downloadable outcomes, integrations, or special randomization technology.

### 5. How Online Coin Flipping Works

H2:

**How Does an Online Coin Flip Work?**

Description:

“The process follows the same basic idea as tossing a physical coin: define two choices, assign them to heads and tails, and use the resulting outcome.”

Create a connected horizontal timeline on desktop and a vertical timeline on mobile:

1. **Step 01 — Identify Your Options** — `bx-list-check`  
   “Choose the two possibilities you want to decide between.”

2. **Step 02 — Assign Heads and Tails** — `bx-git-compare`  
   “Decide which option corresponds to heads and which corresponds to tails before flipping.”

3. **Step 03 — Use the Coin Flip Tool** — `bx-coin-stack`  
   “Visit the homepage and use the existing online coin-flipping tool.”

4. **Step 04 — Read the Result** — `bx-check-double`  
   “Use the displayed heads-or-tails outcome according to the rules agreed upon before the flip.”

Explain the workflow without recreating the tool.

### 6. Everyday Ways to Use a Coin Flip

H2:

**When Can You Use a Coin Flip?**

Description:

“A coin toss can be a practical way to settle informal choices, especially when both possible outcomes are acceptable.”

Create a distinctive gallery with two featured editorial panels and four supporting items on desktop:

1. **Choosing Who Goes First** — `bx-play-circle`  
   “Use a coin toss to decide which player or team begins a casual game.”

2. **Settling Friendly Choices** — `bx-group`  
   “Choose between two acceptable activities or options when everyone agrees to leave the decision to chance.”

3. **Classroom Probability Activities** — `bx-book-open`  
   “Demonstrate the relationship between heads, tails, and theoretical probability.”

4. **Breaking Informal Ties** — `bx-git-compare`  
   “Resolve a friendly tie when a coin toss is an appropriate and agreed-upon method.”

5. **Selecting Sides** — `bx-shuffle`  
   “Determine which participant chooses a side or receives the first selection.”

6. **Making Low-Stakes Decisions** — `bx-check-circle`  
   “Use chance to choose between two options when the consequences are minor.”

Use two columns on tablet and one column on mobile.

### 7. Understanding Heads, Tails, and Probability

H2:

**Understanding the Probability Behind a Coin Flip**

Description:

“Coin tossing is one of the simplest ways to explain probability because a fair coin has two possible outcomes: heads and tails.”

Include a static infographic with two equal segments:

- Probability of Heads = 1/2 = 50%
- Probability of Tails = 1/2 = 50%

Clearly state that these theoretical values assume a fair coin or an unbiased two-outcome random process. Do not claim that the website’s implementation has been independently verified as perfectly unbiased.

H3:

**Does One Flip Affect the Next?**

Copy:

“For independent fair-coin flips, the result of one toss does not change the probability of the next. Even if heads appears several times consecutively, the next flip still has a theoretical 50% probability of heads and 50% probability of tails.”

H3:

**Why Can the Same Result Repeat?**

Copy:

“Repeated heads or tails can occur naturally in a random sequence. A short series of flips does not have to contain equal numbers of both outcomes.”

The infographic must remain static and informational.

### 8. Our Approach to Simple Decision-Making

H2:

**Keeping Simple Decisions Simple**

Description:

“A coin toss is most helpful when the choice is informal, the options are clearly defined, and the people involved agree to use chance.”

Use a large navy editorial statement panel with four supporting principles separated by thin dividers:

- **Clarity:** “Define what heads and tails mean before the flip.”
- **Simplicity:** “Use a coin toss when two straightforward possibilities are available.”
- **Understanding:** “Recognize that random outcomes can repeat and that short streaks are normal.”
- **Appropriate Use:** “Reserve coin tossing for decisions where leaving the outcome to chance is reasonable.”

Prominently include this educational note:

“A coin flip should not replace careful consideration when decisions involve health, safety, finances, legal responsibilities, or other significant consequences.”

### 9. Frequently Asked Questions

H2:

**Frequently Asked Questions About OnlineCoinFlips.com**

Description:

“Learn more about the website, the purpose of online coin flipping, and common questions about heads-or-tails decisions.”

Create an accessible accordion containing:

1. **What is OnlineCoinFlips.com?**  
   “OnlineCoinFlips.com is a website centered on an online coin-flipping tool that provides heads-or-tails outcomes for simple decisions, casual games, and probability-related activities.”

2. **What can I use an online coin flip for?**  
   “You can use it to choose who goes first in a game, settle a friendly tie, decide between two acceptable options, or demonstrate basic probability concepts.”

3. **How do I use the coin flip tool?**  
   “Assign your choices to heads and tails, then use the coin-flipping tool on the homepage. Read the displayed result to determine the selected option.”

4. **Is a coin flip always 50/50?**  
   “A fair coin has a theoretical 50% probability of heads and 50% probability of tails. For a digital tool, the actual distribution depends on how its outcome-generation process is implemented.”

5. **Can a coin land on the same side repeatedly?**  
   “Yes. Repeated heads or tails are possible. In independent fair-coin flips, previous results do not change the theoretical probability of the next outcome.”

6. **How can I contact OnlineCoinFlips.com?**  
   “You can visit the Contact page or email support@onlinecoinflips.com with questions, feedback, or website-related concerns.”

Use semantic buttons, unique IDs, Boxicons for state indicators, `aria-expanded`, `aria-controls`, keyboard accessibility, visible focus styles, and reduced-motion support. Prevent layout jumps and isolate the behavior from Divi accordions.

### 10. Get in Touch

H2:

**Have a Question or Suggestion?**

Description:

“We welcome questions, website issue reports, and suggestions related to OnlineCoinFlips.com.”

Include:

- Email: support@onlinecoinflips.com
- Email URL: `mailto:support@onlinecoinflips.com`
- Contact URL: https://onlinecoinflips.com/contact
- CTA: Contact Us

Use a compact, rounded, professional contact surface with a relevant Boxicon. Do not include a contact form, address, phone number, business hours, or response-time guarantee.

### 11. Final Call to Action

H2:

**Ready to Flip a Coin Online?**

Description:

“Whether you're deciding who goes first or choosing between two simple options, return to the homepage and use the coin-flipping tool.”

Include:

- Primary CTA: Flip a Coin Online  
  https://onlinecoinflips.com/

- Secondary CTA: Explore Features  
  https://onlinecoinflips.com/features

Use a navy background, white text, mint circular accents, an ocean-blue primary button, rounded outer corners, and generous spacing. Do not add an interactive coin.

## Technical implementation requirements

When implementation is requested, return one self-contained WP Coder snippet containing the page HTML, embedded scoped CSS, the Boxicons reference, and isolated vanilla JavaScript. Do not include `html`, `head`, or `body` tags, and do not generate the site header, footer, or global navigation.

Use this exact wrapper:

`#ocf-about-page`

Use prefixed classes such as:

- `ocf-about-intro`
- `ocf-about-overview`
- `ocf-about-purpose`
- `ocf-about-benefits`
- `ocf-about-steps`
- `ocf-about-usecases`
- `ocf-about-probability`
- `ocf-about-principles`
- `ocf-about-faq`
- `ocf-about-contact`
- `ocf-about-cta`

Every custom CSS selector must be scoped beneath `#ocf-about-page`. Never globally target `html`, `body`, headings, paragraphs, links, buttons, images, Bootstrap classes, accordion classes, or Divi’s `.et_pb_*` classes.

Use CSS Grid and Flexbox. Avoid unnecessary `!important` declarations, excessive gradients, heavy effects, and layout-shifting animations.

JavaScript must:

- Use an IIFE or equivalent isolated initialization.
- Select the root directly with `document.querySelector('#ocf-about-page')`.
- Scope all subsequent queries to that root.
- Avoid global variables.
- Avoid duplicate listener registration.
- Handle missing elements safely.
- Never use `document.currentScript` or `previousElementSibling`.
- Never replace `window.dispatch` or modify `Event.prototype`.
- Avoid page-wide document or window listeners.
- Respect `prefers-reduced-motion`.
- Avoid jQuery and external JavaScript dependencies.

Use Boxicons exclusively. Do not use Font Awesome.

## Responsive requirements

Test and optimize at:

- 320px
- 375px
- 414px
- 768px
- 1024px
- 1280px
- 1440px

Use approximately:

- H1: 42–54px on desktop
- H2: 32–42px
- H3: 20–26px
- Body: 15–17px
- Labels: 12–14px
- Body line height: 1.6–1.75
- Desktop section spacing: 80–110px
- Tablet section spacing: 60–80px
- Mobile section spacing: 44–64px

Ensure no horizontal overflow, clipped content, undersized touch targets, unreadable text, or overlapping decoration.
