Chapter 6.5 - The `<area>` Element

Chapter 6 — Multimedia and Interactive Graphics

6.5 The <area> Element

The <area> element defines a clickable region, commonly known as a hotspot, within an image map. It works together with the <map> element to allow different parts of a single image to perform different actions.

Unlike many HTML elements, the <area> element cannot exist independently. It is only valid when used inside a <map> element, which is itself associated with an <img> element through the usemap attribute.

Although its purpose is specialized, the <area> element remains part of the HTML Living Standard and is widely supported by modern browsers.

---

Why the <area> Element Exists

Suppose a website displays a world map.

Instead of dividing the map into several separate images, developers can keep it as one optimized image and define individual hotspots for each continent.

Each hotspot becomes an <area> element.

Examples include:

• Countries
• Continents
• Human anatomy
• Product diagrams
• Building floor plans
• Circuit boards
• Machine components
• Museum layouts

Using <area> keeps the HTML cleaner and reduces the number of image resources required.

---

HTML Living Standard Definition

According to the HTML Living Standard, the <area> element represents either:

• A hyperlink, when the href attribute is present.
• A placeholder region, when no href attribute is provided.

Each <area> belongs to an image map and defines one interactive region.

---

Parent Element

The <area> element is permitted only inside a <map> element.

Correct structure:

<img
    src="world-map.jpg"
    alt="World Map"
    usemap="#world">

<map name="world">

    <area
        shape="rect"
        coords="50,40,180,160"
        href="asia.html"
        alt="Asia">

</map>

The browser associates the hotspot with the displayed image.

---

Content Model

The <area> element is a void element.

It contains no child elements and no closing tag.

Correct:

<area
    shape="circle"
    coords="200,140,60"
    href="earth.html"
    alt="Earth">

Incorrect:

<area>

</area>

Because it is a void element, a closing tag must never be used.

---

DOM Interface

The browser exposes every <area> element through the HTMLAreaElement interface.

This interface provides access to all attributes, allowing JavaScript to inspect and modify hotspots dynamically.

Examples include:

• Reading coordinates
• Updating destinations
• Changing alternative text
• Responding to user interaction

The DOM interface makes image maps fully scriptable.

---

Technical Characteristics

Property	Value
Category	Flow-related image map component
End Tag	Forbidden
Closing Tag	Not permitted
Parent	<map>
Children	None
DOM Interface	HTMLAreaElement

---

Relationship with Other Elements

The <area> element works together with several related HTML elements.

<img>
   │
   │ usemap
   ▼
<map>
   │
   ├── <area>
   ├── <area>
   ├── <area>
   └── <area>

Together these elements create an interactive image map.

---

Browser Processing Overview

When the browser encounters an image map, it performs these steps:

1. Parse the <img> element.
2. Read the usemap attribute.
3. Locate the matching <map> element.
4. Parse every <area> element.
5. Build hotspot regions.
6. Wait for user interaction.
7. Execute the associated action.

This processing occurs automatically without requiring JavaScript.

---

Typical Use Cases

The <area> element is commonly used in:

• Educational websites
• Geography lessons
• Technical documentation
• Interactive product catalogs
• Engineering diagrams
• Medical illustrations
• Museum guides
• Tourism websites
• Manufacturing documentation

Although image maps are specialized, they remain valuable for visual learning experiences.

---

Advantages

Using <area> provides several benefits.

• Multiple links inside one image
• Standards-compliant implementation
• Easy maintenance
• Reduced image duplication
• Interactive user experience
• Excellent browser support

---

Limitations

Developers should also understand its limitations.

• Cannot exist outside <map>
• Coordinates require careful planning
• Responsive layouts require additional attention
• Complex diagrams may require many hotspot definitions

Understanding these limitations helps developers choose the appropriate solution for each project.

---

Practical Example

Imagine an interactive diagram of a computer motherboard.

Each hardware component is represented by an individual <area> element.

Selecting the CPU socket displays installation instructions.

Selecting a memory slot displays RAM compatibility information.

Selecting the storage connector explains supported devices.

The user explores the entire diagram without loading multiple pages.

---

Pro Tip

Think of the <area> element as an invisible hyperlink placed on top of a specific part of an image. The hotspot itself is not visible, but it responds to user interaction based on its defined shape and coordinates.

---

Common Mistakes

Mistake 1

Using an <area> element outside a <map>.

---

Mistake 2

Adding a closing </area> tag.

---

Mistake 3

Forgetting to associate the <map> with an <img> element using the usemap attribute.

---

Mistake 4

Leaving the alt attribute empty when the hotspot conveys important information.

---

Accessibility Note

Each clickable region should have meaningful alternative text. Users of screen readers rely on these descriptions to understand the purpose of each hotspot.

---

SEO Note

Image maps should enhance well-written content, not replace it. Surround diagrams with descriptive text and headings so search engines and users both understand the purpose of the interactive image.

---

6.5.2 Complete Attribute Reference, DOM Interface, and Browser Behavior

The <area> element supports several HTML attributes that define how a hotspot behaves within an image map. Some attributes control navigation, while others improve accessibility, privacy, security, or integration with JavaScript.

This section examines every important attribute in detail.

---

Attribute Overview

Attribute	Purpose	Required
alt	Alternative text describing the hotspot	Yes*
coords	Specifies the hotspot coordinates	Usually
download	Downloads the linked resource	No
href	Destination URL	No
hreflang	Language of the linked resource	No
ping	Sends POST requests after activation	No
referrerpolicy	Controls referrer information	No
rel	Relationship between documents	No
shape	Defines the hotspot geometry	Usually
target	Specifies where to open the destination	No

*When an <area> acts as a hyperlink (href is present), meaningful alternative text should always be provided for accessibility.

---

The alt Attribute

The alt attribute provides a text description of the hotspot.

Example:

<area
    shape="circle"
    coords="220,180,45"
    href="earth.html"
    alt="Planet Earth">

This description is used by assistive technologies and helps users understand the destination of the hotspot.

Good Examples

Asia
Download User Manual
Motherboard CPU Socket
Human Heart

Poor Examples

Click Here
Area 1
Region
Button

Descriptive text is always preferred.

---

The coords Attribute

The coords attribute specifies the position and size of the clickable region.

Its format depends on the selected shape.

Examples:

Rectangle:

<area
    shape="rect"
    coords="40,60,260,180"
    href="asia.html"
    alt="Asia">

Circle:

<area
    shape="circle"
    coords="300,180,70"
    href="earth.html"
    alt="Earth">

Polygon:

<area
    shape="poly"
    coords="40,50,140,30,220,100,180,220,70,200"
    href="country.html"
    alt="Country">

Coordinate systems were discussed in detail in Chapter 6.4 — The <map> Element.

---

The shape Attribute

The shape attribute defines how the browser interprets the coordinate values.

Valid values:

rect
circle
poly
default

Example:

<area
    shape="rect"
    coords="40,60,260,180"
    href="lesson.html"
    alt="Lesson">

Each shape is optimized for different types of diagrams.

---

The href Attribute

The href attribute specifies the destination.

Example:

<area
    shape="circle"
    coords="220,180,45"
    href="earth.html"
    alt="Earth">

Possible destinations include:

• HTML documents
• PDF files
• Images
• Email addresses
• Telephone numbers
• Fragment identifiers
• External websites

If href is omitted, the hotspot does not function as a hyperlink.

---

The target Attribute

The target attribute specifies where the linked resource opens.

Common values:

Value	Description
_self	Current browsing context
_blank	New tab or window
_parent	Parent browsing context
_top	Top-level browsing context

Example:

<area
    shape="rect"
    coords="20,40,180,160"
    href="guide.html"
    target="_blank"
    rel="noopener noreferrer"
    alt="Guide">

For security, use rel="noopener noreferrer" whenever appropriate with _blank.

---

The rel Attribute

The rel attribute describes the relationship between the current page and the linked resource.

Example:

<area
    href="https://example.com"
    target="_blank"
    rel="noopener noreferrer"
    shape="rect"
    coords="20,20,180,160"
    alt="Example">

Common values include:

• noopener
• noreferrer
• nofollow
• external
• license

---

The download Attribute

The download attribute requests that the linked resource be downloaded instead of displayed.

Example:

<area
    shape="rect"
    coords="30,40,220,170"
    href="manual.pdf"
    download
    alt="Download Manual">

The final behavior depends on browser support and server configuration.

---

The hreflang Attribute

The hreflang attribute indicates the language of the linked resource.

Example:

<area
    href="guide-fr.html"
    hreflang="fr"
    shape="rect"
    coords="40,50,200,180"
    alt="French Guide">

It provides language information but does not translate the linked content.

---

The ping Attribute

The ping attribute specifies one or more URLs that receive a POST request when the hyperlink is activated.

Example:

<area
    href="course.html"
    ping="https://example.com/ping"
    shape="rect"
    coords="40,60,200,180"
    alt="Course">

It is commonly used for analytics. Some browsers or privacy settings may disable this feature.

---

The referrerpolicy Attribute

The referrerpolicy attribute controls how much referrer information is sent with the request.

Example:

<area
    href="lesson.html"
    referrerpolicy="strict-origin-when-cross-origin"
    shape="rect"
    coords="30,50,180,160"
    alt="Lesson">

Common values include:

• no-referrer
• origin
• same-origin
• strict-origin
• strict-origin-when-cross-origin

Choose the policy that matches your application’s privacy requirements.

---

Global Attributes

Like most HTML elements, <area> supports global attributes.

Examples include:

• id
• class
• style
• lang
• dir
• hidden
• tabindex
• title

Example:

<area
    id="asiaRegion"
    class="continent"
    title="Asia"
    shape="rect"
    coords="40,60,260,180"
    href="asia.html"
    alt="Asia">

---

Event Attributes

Although modern development generally favors JavaScript event listeners, <area> also supports standard event attributes such as:

• onclick
• onfocus
• onblur
• onkeydown
• onkeyup
• onmouseover
• onmouseout

Example:

<area
    shape="circle"
    coords="220,180,45"
    href="earth.html"
    alt="Earth"
    onclick="console.log('Earth selected');">

For maintainability, attaching events using external JavaScript is recommended instead of inline event attributes.

---

The HTMLAreaElement Interface

In JavaScript, every <area> element is represented by the HTMLAreaElement interface.

Example:

const region = document.querySelector("area");

Common properties include:

• alt
• coords
• download
• hash
• host
• hostname
• href
• origin
• pathname
• port
• protocol
• rel
• search
• shape
• target

These properties allow scripts to inspect and modify hotspots dynamically.

---

Browser Behavior

When the browser processes an <area> element, it typically:

1. Reads the shape.
2. Parses the coords.
3. Calculates the hotspot.
4. Associates it with the destination.
5. Waits for keyboard, mouse, or touch interaction.
6. Performs the requested action.

This behavior is consistent across modern browsers.

---

Practical Example

An online automobile manual displays an engine diagram.

Each <area> represents:

• Battery
• Alternator
• Radiator
• Air filter
• Fuse box
• Engine block

Selecting a component opens maintenance instructions or service documentation.

---

Pro Tip

Keep hotspot names descriptive and consistent throughout your project. Clear naming improves readability and simplifies future maintenance.

---

Common Mistakes

Mistake 1

Providing generic alternative text such as “Area 1.”

---

Mistake 2

Using incorrect coordinate values after replacing the image.

---

Mistake 3

Opening external pages in a new tab without an appropriate rel value.

---

Mistake 4

Using inline JavaScript for complex interactions.

---

Mistake 5

Ignoring keyboard accessibility during testing.

---

Accessibility Note

Every interactive hotspot should communicate its purpose through meaningful alternative text. Users navigating with assistive technologies should receive the same information available to sighted users.

---

SEO Note

Search engines cannot interpret image coordinates as meaningful content. Support every image map with descriptive headings, explanatory paragraphs, and relevant internal links.

---

Summary

In this section, you learned:

• Every major <area> attribute.
• Global and event attributes.
• The HTMLAreaElement interface.
• Browser behavior.
• Accessibility recommendations.
• Security and privacy considerations.

---

Coming Up Next — Section 6.5.3

The next section explores:

• JavaScript integration
• Event handling
• Dynamic hotspot updates
• Browser APIs
• Production examples
• Performance optimization
• Testing and debugging
• Best practices

---

6.5.3 JavaScript Integration, Dynamic Hotspots, Testing, and Professional Implementation

The <area> element is fully integrated with the Document Object Model (DOM), allowing JavaScript to inspect, modify, and respond to hotspot interactions dynamically.

Although image maps can function without JavaScript, modern web applications often combine <area> elements with scripting to create rich, interactive user experiences.

Typical applications include:

• Interactive learning platforms
• Technical documentation
• Medical illustrations
• Geographic information systems (GIS)
• Product demonstrations
• Interactive museum guides
• Industrial equipment manuals

---

Accessing an <area> Element

Every <area> element can be selected using standard DOM methods.

Example:

<map name="computerMap">

    <area
        id="cpuArea"
        shape="rect"
        coords="120,80,260,190"
        href="cpu.html"
        alt="CPU">

</map>

JavaScript:

const cpuArea = document.getElementById("cpuArea");

The variable now references the <area> element.

---

Reading Properties

The HTMLAreaElement interface exposes all important properties.

Example:

console.log(cpuArea.alt);

console.log(cpuArea.coords);

console.log(cpuArea.href);

console.log(cpuArea.shape);

console.log(cpuArea.target);

Possible output:

CPU

120,80,260,190

https://example.com/cpu.html

rect

_self

These properties can be read at any time.

---

Modifying Properties

JavaScript can update hotspot information while the page is running.

Example:

cpuArea.alt = "Central Processing Unit";

Updating coordinates:

cpuArea.coords = "110,75,270,195";

Updating the destination:

cpuArea.href = "processor.html";

The browser immediately applies these changes.

---

Adding Event Listeners

Like other interactive HTML elements, <area> supports DOM events.

Example:

cpuArea.addEventListener("click", function () {

    console.log("CPU selected.");

});

Whenever the hotspot is selected, the event executes before navigation occurs.

---

Preventing Default Navigation

Sometimes developers want to perform an action before opening the destination.

Example:

cpuArea.addEventListener("click", function (event) {

    event.preventDefault();

    alert("Loading processor information...");

});

This technique is useful for displaying dialogs, animations, or confirmation messages.

---

Displaying Dynamic Information

Interactive diagrams often update a content panel instead of navigating to another page.

HTML:

<div id="componentInfo"></div>

JavaScript:

cpuArea.addEventListener("click", function (event) {

    event.preventDefault();

    document.getElementById("componentInfo").textContent =
        "The CPU executes program instructions and performs calculations.";

});

Users receive immediate feedback without leaving the current page.

---

Working with Multiple Hotspots

Large image maps often contain many <area> elements.

Example:

const hotspots = document.querySelectorAll("area");

Loop through every hotspot:

hotspots.forEach(function (region) {

    console.log(region.alt);

});

This approach is useful for analytics, debugging, and dynamic updates.

---

Dynamic Hotspot Generation

Some applications generate hotspots using JavaScript.

Typical workflow:

1. Retrieve coordinate data from a database.
2. Create <area> elements.
3. Assign attributes.
4. Insert them into the <map> element.
5. Register event listeners.

This technique is useful for applications where hotspot data changes frequently.

---

Browser Events

Common events include:

Event	Purpose
click	User activates the hotspot
focus	Keyboard focus enters the hotspot
blur	Keyboard focus leaves the hotspot
keydown	Keyboard key is pressed
keyup	Keyboard key is released
mouseover	Pointer enters the hotspot
mouseout	Pointer leaves the hotspot

Modern applications usually attach these events with addEventListener().

---

Integrating with CSS

The <area> element has no visible appearance and therefore cannot be styled directly.

Instead, developers highlight regions using:

• SVG overlays
• Canvas drawings
• Absolutely positioned elements
• CSS pseudo-overlays
• Tooltip components

This provides visual feedback while keeping the underlying image map intact.

---

Testing Image Maps

Before deployment, test every hotspot carefully.

Recommended checklist:

• Desktop browsers
• Mobile browsers
• Tablets
• Portrait orientation
• Landscape orientation
• Touch interaction
• Keyboard navigation
• Zoomed pages
• High-resolution displays

Testing ensures hotspots remain accurate and usable across devices.

---

Debugging Tips

If a hotspot does not work correctly:

1. Confirm the usemap attribute matches the <map> element’s name.
2. Verify the coordinate values.
3. Ensure the image has loaded completely.
4. Check for overlapping hotspots.
5. Confirm that JavaScript errors are not preventing execution.
6. Test with browser developer tools.

Systematic debugging helps identify issues quickly.

---

Performance Considerations

Image maps are lightweight by design.

To maximize performance:

• Optimize image size.
• Avoid unnecessary event listeners.
• Cache frequently used DOM elements.
• Load large datasets only when required.
• Minimize expensive coordinate recalculations.

These practices improve responsiveness, particularly on mobile devices.

---

Security Considerations

When hotspot information is generated dynamically:

• Validate incoming data.
• Sanitize user input.
• Use HTTPS for external links.
• Avoid executing untrusted scripts.
• Apply an appropriate Content Security Policy (CSP).

Secure coding practices help protect users and applications.

---

Practical Example

An online automotive repair guide displays an engine diagram.

Each hotspot represents a component:

• Engine block
• Battery
• Alternator
• Air filter
• Radiator
• Fuse box

Selecting a hotspot displays maintenance procedures, recommended tools, replacement intervals, and safety warnings without navigating away from the page.

---

Pro Tip

Store hotspot definitions in a structured format such as JSON when building large applications. This makes it easier to update diagrams without modifying HTML manually.

Example structure:

[
  {
    "name": "CPU",
    "shape": "rect",
    "coords": "120,80,260,190",
    "href": "cpu.html"
  }
]

This approach scales well for complex projects.

---

Common Mistakes

Mistake 1

Attempting to style the <area> element directly with CSS.

---

Mistake 2

Using inline JavaScript instead of external scripts.

---

Mistake 3

Ignoring touch interactions on mobile devices.

---

Mistake 4

Updating image dimensions without recalculating hotspot coordinates.

---

Mistake 5

Not testing keyboard navigation.

---

Accessibility Note

Interactive image maps should always have a keyboard-accessible alternative, such as a list of text links below the image. This ensures users who cannot use a pointing device can still access the same information.

---

SEO Note

Use descriptive captions, headings, and surrounding content to explain the purpose of an image map. Search engines rely on textual context rather than hotspot coordinates when indexing content.

---

Summary

In this section, you learned:

• How JavaScript interacts with the <area> element.
• Reading and modifying hotspot properties.
• Event handling.
• Dynamic hotspot generation.
• Testing and debugging techniques.

SEO Checklist

To improve search engine visibility:

• Use descriptive page titles.
• Include relevant headings.
• Explain the diagram in surrounding text.
• Add informative captions.
• Use meaningful internal links.
• Avoid placing essential content exclusively inside image maps.

Search engines primarily analyze HTML content rather than image coordinates.

---

Performance Checklist

For the best performance:

• Compress images.
• Choose appropriate image formats.
• Reduce unnecessary JavaScript.
• Cache static resources.
• Test page loading on slower networks.
• Keep hotspot definitions organized.

Optimizing images often has a greater performance impact than optimizing the image map itself.
