Creating CSS3 Triangles with Background Images for Seamless Triangle-Shaped Links
Introduction
Enhancing your website's aesthetics with interactive triangle-shaped links can elevate its visual appeal. With CSS3, you can effortlessly create these geometric shapes and incorporate background images to add depth and charm.
The Challenge of Transparent Hover Zones
However, a common issue arises when creating triangles: the inability to hover over the transparent portions of the background images. This hurdle prevents visitors from accessing the underlying links.
The Solution: Leveraging Child Images
To overcome this challenge, consider using child images for your links instead of background images. By implementing this approach, you can independently skew the parent triangle elements while maintaining the alignment of their child image links.
Code Implementation
Here's the code that demonstrates how to implement this technique:
HTML:
<div>
Relevant CSS:
.pageOption {
overflow: hidden;
position: relative;
width: 40em; height: 27em;
}
.option, .option img { width: 100%; height: 100%; }
.option {
overflow: hidden;
position: absolute;
/* arctan(27 / 40) = 34.01935deg
* need to skew by 90deg - 34.01935deg = 55.98065deg
*/
transform: skewX(-55.98deg);
}
.option:first-child {
left: -.25em;
transform-origin: 100% 0;
}
.option:last-child {
right: -.25em;
transform-origin: 0 100%;
}
.option img {
transform: skewX(55.98deg);
transform-origin: inherit;
}
Conclusion
By employing child images for your links and skillfully aligning them with skewed triangle elements, you can achieve seamless hoverability over the entire triangle shapes. This technique enhances the interactivity and visual appeal of your website, providing a more engaging user experience.

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.

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.
