How to Eliminate Sticky Hover Effects on Buttons for Touch-Enabled Devices
When creating carousels with permanent navigation buttons, a common issue arises on touch devices. The buttons' hover states, typically appearing blue, become "sticky," remaining activated even after tapping. Several approaches to address this problem have been explored:
- Adding a no-hover class on touchend can resolve the issue, but it might impact performance and introduce compatibility issues on devices like Chromebooks with both touch and mouse capabilities.
- Implementing a touch class to the documentElement and modifying CSS accordingly can also address the problem, but it's not optimal for devices with both touch and mouse support.
An ideal solution would be to remove the hover state upon touchend. However, no direct method is available for this. Focusing on another element does not remove the hover state. While tapping on another element manually does, triggering this action programmatically in JavaScript remains a challenge.
To solve this issue effectively, you can leverage recent developments in CSS Media Queries Level 4:
@media (hover: hover) {
button:hover {
background-color: blue;
}
}
This CSS essentially states, "If the device supports true hovering (e.g., has a mouse-like primary input device), apply the button hover style."
For browsers where this feature is not yet implemented, a JavaScript polyfill can be utilized to detect hover support and toggle a custom class, allowing you to apply the hover style conditionally:
html.my-true-hover button:hover {
background-color: blue;
}
$(document).on('mq4hsChange', function (e) {
$(document.documentElement).toggleClass('my-true-hover', e.trueHover);
});
This solution effectively eliminates sticky hover effects for touch devices while maintaining desired aesthetics on devices with mouse input.

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.
