An Introduction to jQuery Scroll-based Animations
Article Introduction：Core points

JavaScript Animations in AngularJS Applications
Article Introduction：Core points
AngularJS is an excellent framework for building single-page web applications, and its animation support is one of its key features. JavaScript animations can be used to add animation effects to AngularJS applications. The difference between CSS and JavaScript animations is only in the way they are defined.
Custom Angular JavaScript animations are defined in the animation method of the Angular module. The animation name begins with a dot. Each animation operation accepts two parameters: the object representing the current DOM element that will be applied to the animation, and the callback function called after the animation is completed.

CSS Animations
Article Introduction：CSS animation: The key tool to enhance user experience
Core points:
CSS animation is a key tool to enhance the user experience, adding depth and meaning to interactions, guiding users to browse the interface, and providing user action feedback.
While JavaScript also provides animation features, CSS is the easiest way to get started with animation. JavaScript-based animations can be more complex and resource-intensive, which may slow down page loading times on slower connections or mobile devices.
CSS animations can be launched immediately with just a web browser and text editor, an easy to access and efficient way to bring your design to life. CSS animation has great potential, from smooth transition to using keyframes to creating complex effects.
Animation is becoming a must

Is it necessary to learn how to make H5 pages?
Article Introduction：For learning H5 or not, the answer depends on the individual goal. If you only need to create a static page, you don't need to learn H5 in depth. But if complex features such as interaction, animation or games are required, H5 is a must-have skill. H5 is the basis for building web pages, and it is necessary to use CSS (responsible for appearance) and JavaScript (giving dynamic effects) to create amazing pages. During the learning process, you need to pay attention to browser compatibility and performance optimization, and master debugging skills. Proficiency in H5 takes time and practice, and as a first step for a web front-end engineer, you need to learn more in-depth knowledge and skills.

Improve Browser Performance With the CSS Stress Test Tool
Article Introduction：CSS3 special effects improve development efficiency, but also affect performance. This article introduces a bookmarking tool called CSS Stress Test, which can help developers identify CSS code that causes website performance problems.
The background, rounded corners, shadows, transparency and transformation of CSS3 greatly simplifies the web development process and avoids the use of image slicing, extra elements or scripts. However, these features can also have a significant impact on browser performance. A few years ago, when I first tried these technologies, I was stunned by the impact on browser performance. A simple CSS property can lead to obvious redrawing and page scrolling stuttering. In one project, I had to give up rounded corners and use pictures to solve performance problems.
