Eliminating Sticky Hover Effects on Buttons in Touch-Enabled Environments
The prevalence of hover effects on buttons creates an issue when it comes to touch devices. The hover state, often indicated by a color change, tends to persist even after tapping the button, resulting in a "sticky" effect. This behavior can be undesirable and interferes with user experience.
To address this issue, numerous approaches have been proposed with varying degrees of success:
- Adding a "no-hover" class on touchend: While this method effectively prevents the hover effect after tapping, it can negatively impact performance and fails to handle devices with both touchscreen and mouse input.
- Adding a "touch" class to the documentElement: This approach also presents challenges in devices that support both touch and mouse input, as it cannot distinguish between the two inputs.
The ideal solution to this problem would be removing the hover state immediately after touching the button. Unfortunately, this functionality is not natively supported by browsers. Attempting to focus another element or manually tap another element do not produce the desired result.
A Perfect Solution:
The implementation of CSS Media Queries Level 4 provides a definitive solution to this problem. Using the following code:
@media (hover: hover) {
button:hover {
background-color: blue;
}
}
browsers that support true hovering (e.g., with mouse input) will apply the hover style only when the hover event is genuine.
For browsers that do not support this feature, a polyfill is available that allows you to emulate the behavior. This polyfill enables you to use the following CSS:
html.my-true-hover button:hover {
background-color: blue;
}
Finally, using the polyfill's JavaScript, you can dynamically toggle the presence of the "my-true-hover" class based on the device's hover support. This approach effectively replicates the behavior of true hover detection, providing a perfect solution to the sticky hover effect issue on touch devices.

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.
