Simulating Hover Effects on Touch Devices
With the widespread use of touch-enabled devices, replicating classic mouse interactions such as hover effects can be a challenge. This issue arises when attempting to create hover effects using CSS alone, as it only applies to mouse inputs. Fortunately, there is a solution that involves incorporating JavaScript and modifying the CSS.
Implementing the Simulation
To simulate hover effects on long touch, follow these steps:
- Add a class called "hover" to the HTML element where you want the hover effect to occur.
- Add the following JavaScript code to enable touch handling:
$(document).ready(function() {
$('.hover').on('touchstart touchend', function(e) {
e.preventDefault();
$(this).toggleClass('hover_effect');
});
});
- In the CSS, modify the hover effect definition to include the ".hover_effect" class:
element:hover, element.hover_effect {
rule:properties;
}
- Optionally, add the following CSS to disable browser selection on touch:
.hover {
-webkit-user-select: none;
-webkit-touch-callout: none;
}
Explanation
This solution takes advantage of the 'touchstart' and 'touchend' events triggered on touch-enabled devices. When the user's finger touches the screen, the 'touchstart' event triggers and adds the 'hover_effect' class to the HTML element with the "hover" class. When the touch ends, the 'touchend' event is fired, removing the 'hover_effect' class, effectively simulating the hover effect.

How can I include CSS only on some pages?
Jun 11, 2025 am 12:01 AM
There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.
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.

CSSCounters is a tool for creating automatic numbers. 1. Basic usage: define and operate counters through counter-reset and counter-increment, such as "SectionX." before h2. 2. Advanced usage: Use nested counters to create complex numbers, such as chapter and section numbers. 3. Notes: Ensure the counter is reset correctly, optimize performance, and simplify counter logic. 4.
