Update your website: Why should you consider using CSS3 animations instead of relying solely on jQuery?

In modern web design, animation effects have become an important part of attracting user attention and improving user experience. In the past, using jQuery was one of the main methods to implement web page animation. However, with the emergence of CSS3 animations, more and more developers are choosing to use CSS3 animations to replace or supplement jQuery animations. This article will explore why we should consider using CSS3 animations instead of relying solely on jQuery, and use code examples to demonstrate the power of CSS3 animations.

1. Performance advantages

Using CSS3 animation can take advantage of the browser's hardware acceleration to reduce the burden on the JavaScript engine, thereby improving the performance of the web page. In contrast, using jQuery to implement animation relies on JavaScript to calculate and operate the DOM, and its performance is relatively low. Especially on mobile devices, CSS3 animations can be better optimized to run smoothly, while jQuery animations can suffer from stuttering and delays in some cases.

The following is a simple code example that compares the use of CSS3 animation and jQuery animation to achieve the gradient effect of an element:

CSS3 animation example:

.my-element {
  transition: background-color 1s;
}

.my-element:hover {
  background-color: red;
}

jQuery animation example:

$(".my-element").hover(function() {
  $(this).animate({ backgroundColor: "red" }, 1000);
}, function() {
  $(this).animate({ backgroundColor: "transparent" }, 1000);
});

It can be seen from the comparison that using CSS3 animation to achieve gradient effects can achieve smooth animation effects by simply defining transition properties and mouse hover states. Using jQuery animation to achieve the same effect requires additional JavaScript calculations and DOM manipulation, and the code is relatively complex.

2. Better browser compatibility

CSS3 animation is a W3C standard and can be well supported in modern browsers. The jQuery animation needs to rely on the JavaScript library, which may be affected by the browser's different support for JavaScript parsing and execution. Using CSS3 animation can ensure the consistency and stability of the animation in various browsers without having to consider the compatibility of different browsers with jQuery.

3. More concise code

The code of CSS3 animation is usually more concise and clear than using jQuery animation. By using CSS3's keyframe animation and transition properties, complex animation effects can be easily achieved without writing a lot of JavaScript code. In comparison, the implementation process of jQuery animation requires more code, especially when dealing with complex animation effects.

Code example:

CSS3 keyframe animation example:

@keyframes slidein {
  from { left: -100px; }
  to { left: 0; }
}

.my-element {
  animation: slidein 1s;
}

jQuery animation example:

$(".my-element").animate({ left: 0 }, 1000);

4. Better maintainability and scalability

Using CSS3 animation can separate animation effects from HTML and CSS code, making the code easier to maintain and expand. We can control the triggering and stopping of animations by adding or removing CSS classes for elements without the need to frequently operate the DOM and modify JavaScript code. This code structure makes the structure, style and behavior of the web page more clearly separated and facilitates subsequent maintenance and expansion.

In summary, although jQuery animation was widely used in the past, more and more developers are now beginning to consider using CSS3 animation to achieve web page animation effects. CSS3 animation has the advantages of performance advantages, better browser compatibility, concise code, and good maintainability and scalability. By gradually moving to using CSS3 animations, we are able to provide users with a smoother web animation experience and make our website more modern and efficient.
