What is CSS+DIV?

CSS+DIV is one of the commonly used terms in website standards (or "WEB standards"). It is usually used to explain the difference from the table positioning method in the HTML web design language, because in the XHTML website design standard , no longer use table positioning technology, but use css div to achieve various positioning.

CSS is the abbreviation of English Cascading Style Sheets. It is a computer language used to express file styles such as HTML or XML.

The DIV element is an element used to provide structure and background for block-level content within an HTML document. Everything between the start and end tags of the DIV is used to form the block, and the properties of the contained elements are controlled by the properties of the DIV tag, or by formatting the block using a stylesheet.

Advantages and problems of CSS+DIV website design

advantages, but there are also some problems with the CSS+DIV model in website construction applications. This article combines the experience of website technology and designers, and from the perspective of online marketing applications, summarizes the advantages and problems of CSS + DIV website design as follows:

Advantages of CSS + DIV website design

First of all, CSS The great advantage lies in concise code, which can save a lot of bandwidth for a large website, and as we all know, search engines like clean code (the real meaning is that it increases the proportion of effective keywords in the total code of the web page), so Websites made using CSS+DIV web standards have certain advantages of being search engine friendly.

Secondly, the website produced by CSS DIV makes website revision relatively simple. Many problems only require changing CSS without changing the program, thus reducing the cost of website revision.

Issues with CSS+DIV website design

Although CSS DIV has certain advantages, the problems in CSS DIV website construction at this stage are also relatively obvious, mainly reflected in:

Chapter First, the high reliance on CSS makes web design more complicated. Compared with the table layout (table) in HTML4.0, although CSS DIV is not out of reach, it is at least much more complicated than table positioning. Even for website design experts, it is easy to have problems, let alone beginners. To a certain extent, it has affected the popularization and application of XHTML website design language.

Second, abnormal CSS files will affect the normal browsing of the entire website. The design elements produced by CSS websites are usually placed in several external files. This one or several files may be quite complex or even large. If the CSS file is called abnormally, the entire website will become miserable.

Third, the browser compatibility issue with CSS website design is quite prominent. Web design based on HTML4.0 has almost no browser compatibility issues in versions after IE4.0. However, a website designed with CSS DIV may display pages normally in IE but not in Firefox. It’s unrecognizable (which is why Internet marketers are advised to use Firefox). CSS DIV still needs further support from various browser manufacturers.

Fourth, whether CSS DIV is optimized for search engines depends on the professional level of web design rather than CSS DIV itself. CSS DIV web design does not guarantee that the web page will be optimized for search engines. It does not even guarantee that the web page will have a simpler code design than the HTML website. Moreover, the inclusion and sorting of web pages by search engines is obviously not measured by whether tables and CSS positioning are used. This This is the reason why many websites made with traditional table layouts are ranked high in search results, while many web pages made using CSS and web standards are still ranked low. Because for search engines, factors such as website structure, content, and related website links are always the most important indicators for website optimization.
