Compared with the traditional TABLE page layout, CSS+DIV has the following four significant advantages: 1: Design and content can be distinguished
 Separate the design part and put it in a separate style file. The HTML file only stores text information.
 2: Improve the efficiency of search engines in indexing web pages
 Replace nested tags with HTML containing only structured content, and search engines will search your web content more effectively.
 3: Improve page browsing speed
 For the visual effect of the same page, the page capacity of CSS+DIV reconstruction is much less than that of TABLE encoded page syntax. The former is generally only half the size of the latter.

 4: Easy maintenance and revision
 Simply modify a few CSS files to redesign the page of the entire website.
 From the above description, using CSS+DIV to create websites can improve the friendliness of website users and search engines.
 The core reason why CSS+DIV has become the mainstream of current web design is not only that it conforms to the W3C standard, but also that by using CSS+DIV, web programs are better than others, and design and programs have been separated.
 Now there are a lot of div+css, and all major websites have been remade into div+css mode. With the adoption of layers and CSS, the web page opens much faster.
