Compared with the table layout (table) in html4.0, CSS + div is at least more complex than table positioning, even if it is difficult for a website designer, not to mention beginners, which affects the popularization and application of the XHTML website design language to a certain extent.

Second, an exception in the CSS file will affect the normal browsing of the entire website. The design elements of CSS websites are usually put in several L external files, which may be quite complex or even large. If the CSS file call is abnormal, the whole website will become terrible.

Third, the problem of browser compatibility in CSS website design is prominent.

This is why many websites with traditional table layout are ranked first in the search results, there are many reasons why the ranking of web pages made using CSS and web standards is still low. Because for search engines, factors such as website structure, content, and related website links are always the most important indicators for website optimization.
