As our comprehensive guide explains, while you can wrap any HTML segment within an <a href=""></a> tag (let's call this a "block link"), linking an entire content "Card" to create a large clickable area isn't ideal.
<a href="http://www.miracleart.cn/link/bc02850ceec640422e0cd11a6a4b827e">
<div>
<h2>Card</h2>
<img src="/static/imghw/default1.png" data-src="https://img.php.cn/" class="lazy" alt="Block Links Are a Pain (and Maybe Just a Bad Idea) "><p>Content</p>
</div>
</a>
Adrian Roselli highlights a significant accessibility issue: wrapping the entire block in a link causes screen readers to announce the entire content as a single, lengthy link, significantly impacting usability.
Therefore, avoid this approach. A better alternative is to link only the header:
<div> <h2><a href="http://www.miracleart.cn/link/bc02850ceec640422e0cd11a6a4b827e">Article</a></h2> <img src="/static/imghw/default1.png" data-src="https://img.php.cn/" class="lazy" alt="Block Links Are a Pain (and Maybe Just a Bad Idea) "><p>Content</p> </div>
Expanding the clickable area to encompass the entire card can be achieved using CSS:
.card {
position: relative;
}
.card h2 a::after {
content: "";
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
This addresses the accessibility problem, but introduces another: text selection becomes cumbersome. A simple click initiates the link, preventing natural text selection within the card. While not entirely blocking selection, it's significantly less user-friendly.
A JavaScript solution to detect text selection before triggering the link is conceivable, but feels like an overly complex and potentially unreliable workaround.
Refer to Heydon's insightful discussion on "The redundant click event" in his Cards article for further context.
In conclusion, block links present considerable challenges. While a perfect solution remains elusive, the drawbacks outweigh the benefits in most scenarios. We encourage alternative approaches to achieve large clickable areas.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

Work through the PostCSS plug-in form, parse CSS, analyze attributes that need to be prefixed, and generate code according to configuration; 3.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
