What is Div + CSS?

I wrote about Div + CSS layout for webpages in the previous section. ArticleAt that time, it may be too simple to write. Some friends yelled at me.
Today, I will discuss in detail about Div + CSS and how to use Div + CSS to layout pages:
When using Dreamweaver to design webpages, we often use visual windows to visually Design tables or other webpage elements, the style of the webpage element is defined. We often use the Dreamweaver CSS style to define webpage elements.
You can search for the reasons for using Div + CSS instead of table + CSS. The obvious advantage of using Div + CSS is ease of maintenance and convenient reuse, in the future, you only need to modify the CSS file to modify the website style, and the client access speed will be improved, but there will also be negative issues. For example, if the CSS file is damaged, the whole site page will be messy.
Now let's get down to the point. You can open my recently written article: vs2005 + access to develop website management system logs.
The series of articles uses Div + CSS for layout.
By defining some nested Div on the page, you can take the unique ID or class of all the DIV that requires CSS definition, and then define the style in the CSS file, of course, you must introduce this CSS file to the page.
The source code for the specific page Div definition and CSS definition has been provided in the above-mentioned article. You can refer to it and we will not repeat it here! I hope my friends read this time. Don't say it's too complicated.
