Css+div Web Design (iii)--hybrid applications with multiple technologies

This blog will introduce a mix of CSS and a variety of technologies, JavaScript can make our pages more convenient to interact with, XML makes data storage and convenient, AJAX asynchronous update can speed up our page loading speed.

1. css and JavaScript

Since the basics of JavaScript have been discussed here, there is no more introduction to http://blog.csdn.net/jinfulin/article/details/38406273

To give you a practical example, let's take a closer look at the strengths of CSS and JavaScript.

<span style= "FONT-SIZE:18PX;" >

Output Result:

2. CSS and XML
The basic explanation of XML is also mentioned earlier. http://blog.csdn.net/jinfulin/article/details/38355509
Xml+div is actually relatively simple, very similar to HTML, just add the appropriate style
Look at one of the simplest examples
<span style= "FONT-SIZE:18PX;" ><?xml version= "1.0" encoding= "gb2312"? ><?xml-stylesheet type= "Text/css" href= "14-5.css"? ><! DOCTYPE hello[<! ELEMENT Hello (#PCDATA) >]>

<span style= "FONT-SIZE:18PX;" ><?xml version= "1.0" encoding= "gb2312"? ><?xml-stylesheet type= "Text/css" href= "14-5.css"? ><! DOCTYPE hello[<! ELEMENT Hello (#PCDATA) >]>

Output Result:


3. CSS and Ajax
The core of Ajax is the JavaScript object XMLHttpRequest. This object was first introduced in InternetExplorer5, which is a technique that supports asynchronous requests.
I don't have a system to learn about Ajax, just to show you an example.
<span style= "FONT-SIZE:18PX;" >

Finally, to make a beautiful and useful website, you have to use a variety of technology mixed applications. Only by mastering these technologies can we make our web development more smoothly.
