CSS :target pseudo-class

The :target pseudo-class in CSS is a powerful tool that enables developers to style elements based on the presence of a specific target in the URL. This capability allows for dynamic styling changes, enhancing user interaction and visual feedback on websites. In this article, we’ll explore the :target pseudo-class, demonstrate its usage with examples, and discuss some best practices for implementation.

I. Introduction

A. Definition of :target pseudo-class

The :target pseudo-class matches an element whose id attribute is specified in the URL fragment identifier (the part of the URL after the #). For instance, in the URL example.com/#example, the element with id=”example” will be targeted.

B. Purpose and functionality

The primary purpose of :target is to apply styles dynamically as navigation occurs on a page. When a specific link is clicked that points to an element’s ID, the style changes, allowing developers to create interactive elements like tabbed interfaces, modal windows, and other sleek navigational features.

II. Browser Support

The :target pseudo-class is widely supported across all major browsers, including:

Google Chrome
Mozilla Firefox
Safari
Microsoft Edge
Opera

B. Compatibility notes

As of the latest updates, there are no significant compatibility issues with the :target pseudo-class. It should work seamlessly across all major browsers, but testing in older versions might be advisable for legacy projects.

III. Syntax

A. Structure of the :target selector

The basic syntax for using the :target pseudo-class is as follows:

element:target {
    /* CSS properties */
}

B. Usage examples

Let’s look at a simple example:

#section1:target {
    background-color: lightblue;
}

In this example, when a link points to #section1, that section’s background will change to lightblue.

IV. Usage

A. How to use :target in styling

Using the :target pseudo-class involves creating links that reference the ID of an HTML element. When an element is targeted, you can apply various CSS styles to enhance user experience.

B. Scenarios and practical applications

The :target pseudo-class can be utilized in various interactive scenarios:

Toggle Visibility: Hide and show elements like dropdowns or panels.
Tabbed Navigation: Switch between content without JavaScript.
Image Galleries: Display specific images when a thumbnail is clicked.

C. Example code snippets

Here is an example demonstrating the use of the :target pseudo-class for a simple tabbed interface:

<style>
.tab {
    display: none;
}
.tab:target {
    display: block;
}
</style>

<body>
    <a href="#tab1">Tab 1</a>
    <a href="#tab2">Tab 2</a>
    
    <div id="tab1" class="tab">
        <p>Content for Tab 1</p>
    </div>
    
    <div id="tab2" class="tab">
        <p>Content for Tab 2</p>
    </div>
</body>

In this example, when a user clicks on a tab link, the corresponding content appears while hiding others.

V. Related CSS Properties

Numerous CSS properties can complement the :target pseudo-class:

display: Control visibility of elements.
opacity: Create fade-in effects.
background-color: Change background to draw attention.
