Advantages of XHMTL+CSS website creation

First of all, the great advantage of CSS lies in its simple code, which can save a lot of bandwidth for a large website, and it is well known that search engines like clean code. Its real significance is to increase the proportion of effective hub words in the total code of web pages, so the website made using CSS+DIV 's web standard has the advantage of search engine friendliness.

Secondly, the website made by xhtml+css makes the website revision relatively simple, and many topics only need to change the CSS without changing the program, thus reducing the cost of website revision.

The disadvantages of making XHMTL+CSS website

Although xhtml+css has a certain advantage, the problems existing in the construction of xhtml+css website at this stage are also quite significant, mainly as follows:

First, the high reliance on CSS makes website production more complicated. Relative to the table layout in HTML4.0, although xhtml+css is not out of reach, at least it is more complex than table positioning, even for website production experts, it is easy to raise questions, let alone beginners, which to a certain extent affected the popularity and application of XHTML website production language.

Second, the abnormal CSS file will affect the normal browsing of the whole website. The design elements produced by the CSS website are usually placed in several l external files, which may be relatively complex or even large. If the CSS file call is abnormal, then the whole site will become miserable.

Third, the problem of browser compatibility made by CSS website is more prominent. There are few browser compatibility issues in post-IE5.0 versions of HTML4.0-based websites, but the pages that xhtml+css-designed sites normally display in IE browsers may change beyond recognition in FireFox. Xhtml+css needs further support from various browser vendors.

Fourth, whether xhtml+css optimizes search engines or not depends on the professional level of website production rather than xhtml+css itself. The creation of xhtml+css websites does not guarantee the optimization of web pages to search engines, or even a simpler code design than HTML sites, and the inclusion and ranking of web pages by search engines are obviously not measured by whether or not to use tables and CSS positioning, which is why many sites made by traditional table layouts rank first in search results. The reason why many pages made using WEB and CSS are still at the bottom of the rankings. For search engines, website structure, content, related website links and other factors are always important indicators of website optimization.
