jQuery Animated CSS Class Transitions for Smooth DOM Element Color Changes
Introduction
In this article, we address the challenge of animating CSS attribute changes on various objects using jQuery while maintaining control over stylesheet definitions.
Example 1: Animate with Dedicated CSS Properties
Using animate(), we can directly manipulate CSS properties within the animation code:
$('#someDiv').mouseover(function() {
$(this).stop().animate({ backgroundColor: 'blue' }, { duration: 500 });
}).mouseout(function() {
$(this).stop().animate({ backgroundColor: 'red' }, { duration: 500 });
});
However, this approach separates style definitions from the stylesheet, which is less desirable.
Example 2: AddClass/RemoveClass Alternative
To leverage stylesheet classes, we can use addClass() and removeClass(), as demonstrated below:
$('#someDiv').addClass('blue').mouseover(function() {
$(this).stop(true, false).removeAttr('style').addClass('red', { duration: 500 });
}).mouseout(function() {
$(this).stop(true, false).removeAttr('style').removeClass('red', { duration: 500 });
});
While some animations work as expected, others are disrupted due to the temporary style applied during animation.
Ideal Solution
We aspire to maintain CSS class definitions in one place (the stylesheet) while utilizing jQuery for animated class transitions.
Proposed Solution
To achieve this, we recommend leveraging CSS transitions in combination with jQuery's class manipulation capabilities. Check out this live example for a demonstration:
<div>
#someDiv {
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}
$('#someDiv').mouseover(function() {
$(this).addClass('blue');
}).mouseout(function() {
$(this).removeClass('blue');
});The above is the detailed content of How Can jQuery and CSS Transitions Smoothly Animate DOM Element Color Changes?. For more information, please follow other related articles on the PHP Chinese website!

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.
