Second, iScroll frame

1. Solve the pain points
• iScroll will be born, mainly because whether it is on iphone, ipad, android or earlier mobile Webkit does not provide a native way to support scrolling content in a fixed-height container
• The above situation leads to all web-app requirements. Simulate into an app When it looks like, it can only be composed of an absolutely positioned header or footer plus a middle area where the content can be scrolled
• iScroll frame solution The pain point is that it can simulate this missing feature and provide a native way to support scrolling content in a fixed-height container
2. Official website< /li>
   • Download address: http://cubiq.org/iscroll-4
   • The 4 version is the most stable, with more data, and convenient to use

• Compatibility Questions
5. Main role in the project

  < /li>

• Handle compatibility issues on the mobile terminal, and improve the speed and performance of the project
• As for the parameter method of the framework itself, we Not used here

Three, Less use

Four. Animation library animate.css library

1. Solve the pain points
• When designing more complex animation effects by yourself, it is time-consuming and inefficient
In order to effectively complete various animation effects, I wrote some of the more commonly used animation effects into an animation library, so that everyone can complete the css3 animation

2. Introduction
• animate.css has a lot of typical css3 animations built in, with good compatibility, easy to use, and can be used across browsers An animation library. It is worth using in projects that need to write animation
• https://daneden.github.io/animate.css/
3. How to use the animation library
1. The first type
• First introduced animate.css library file
• Add the specified animation style name to the specified element
• Two class names are included here. The first is a basic style name that must be added. Any element that wants to animate must add this class name. The second is the specified animation style name
• If you want to dynamically add an animation style to an element, you can do it through jquery
• $(‘#demoId’).addClass(‘animated shake’)
1. Second type
• No need to introduce the animate.css library file
• Find the desired animation name through the effect display, open the animation library, and pass Find the desired effect code by name
• Copy the effect code in the animation library directly to your own css
• Add it yourself Animation rules can be used
2. Comparison of the two methods:
• The first one will cause code redundancy and is simple to use
• The second method does not have code redundancy and is relatively complicated to use, but the second method is still recommended
