DIV CSS is a WEB design standard, which is a web page layout method. Different from the traditional way of positioning through table layout, it can realize the separation of web page content and presentation.

Advantages of using DIV CSS layout

1. Comply with W3C standards.

This ensures that your website will not be obsolete due to future network application upgrades.

2. More friendly to viewers and browsers.

Because CSS is rich in styles, it makes the page more flexible. It can achieve unified and non-deformed display effects according to different browsers. This supports browser backward compatibility, which means that no matter who wins the browser war in the future, your website will be well compatible.

3. Streamlined code makes the page load faster and increases user experience.

Using DIV CSS layout, the page code is streamlined. I believe everyone who knows XHTML knows this. . Code simplification improves the crawling efficiency and efficiency of Baidu Spider, which can crawl the entire page in the shortest time. At the same time, this has certain benefits for the quality of collection.

And the page size becomes smaller and the browsing speed becomes faster. Since most of the page code is written in CSS, the page volume and capacity become smaller. Compared with the table nesting method, DIV CSS separates the page into more areas, which are loaded layer by layer when the page is opened. Instead of enclosing the entire page in a large table like table nesting, the loading speed is very slow.

If the loading speed is improved, the waiting time for users to click on the page will be less. The increase in user experience will result in the website being liked by search engines, thereby improving the website ranking.

4. Maintain visual consistency.

The previous method of making nested tables would cause deviations in the display effect between pages or between regions. Using the DIV CSS production method, all pages or all areas are uniformly controlled by CSS files, which avoids effect deviations reflected in different areas or different pages.

5. Be more efficient when modifying the design.

Due to the use of DIV CSS production method, the content and structure are separated, making it easier to save time when modifying the page. According to the regional content tag, find the corresponding ID in CSS, which makes it more convenient to modify the page, and will not destroy the layout style of other parts of the page. It is easier to divide labor and reduce interdependence in team development.

6. Search engines are more friendly.

Compared with traditional tables, web pages using DIV CSS technology write most of the HTML code and content styles into CSS files, which makes the code in the web page more concise and the text part more prominent. Obviously, it is easy to be collected and included by search engines.

div css has a clear structure and is easy to be searched by search engines. It is naturally suitable for optimizing seo, reducing the size of the web page, and making the web page smaller. Note: The structure of div css is clear and concise, which does not mean that all div css structures can be used. For example, the entire HTML tag is all DIV. It seems that except for the above and above , the rest are

, it is as if the entire HTML is composed of ten thousand unrelated contents, or the entire HTML is structured as

, as if all the elements of this page are lists. In fact, these two situations are quite common. Because of the misunderstanding of the true meaning of "DIV CSS", perhaps there should be no such term at all, because it is almost impossible to complete a complete page with only DIV CSS.

Extended information:

"DIV CSS" is actually a wrong name, and the standard name should be XHTML CSS. Because DIV and Table are both marks in XHTML or HTML language, and CSS is just a form of expression. Maybe the original intention of the proposer is not wrong, but the followers misinterpreted its meaning and believed that the entire page should be a combination of DIV CSS files.
