 所有用户都想把网站做到完美,在网页的设计中要优化网站的布局、标签等等,利用DIV+CSS不仅可以精美的布局网页,还有助于搜索引擎抓取网页内容,提高网站排名。当然它的好处还有很多:
All users want to make the website perfect. In the design of web pages, we should optimize the layout and labels of the website. Div + CSS can not only beautifully layout the web pages, but also help search engines capture the web content and improve the website ranking. Of course, it has many advantages:
一、代码精简
1、 Code reduction
采用DIV+CSS布局使代码很精简,这一点相信对此方法熟透的朋友都有所了解的都知道,css文件可以在每一个网页中使用,只要调用就可以,采用table表格修改一些页面的话就很麻烦了,如果是一个门户网站的话,要手动改很多页面,而且看着那些表格也会感觉很乱也很浪费时间,但是这要是在css中只要改一个代码就可以了
Using div + CSS layout makes the code very concise. I believe all friends who are familiar with this method know that CSS files can be used in every web page. As long as they are called, it is very troublesome to modify some pages using table table. If it is a portal website, many pages need to be changed manually, And looking at those tables will feel messy and waste time, but if you change a code in CSS, it's OK
二、表格嵌套
2、 Table nesting
使用Table布局,为了达到一定的视觉效果,不得不套用多个表格,这样不仅表格会很多,还很乱;所以使用table为了达到很好的视觉效果,就要嵌套很多表格,这就会有很多的代码,不利于搜索引擎抓取。
Using the table layout, in order to achieve a certain visual effect, you have to apply multiple tables, which will not only have many tables, but also be messy; Therefore, in order to achieve a good visual effect, many tables need to be nested, which will have a lot of code, which is not conducive to search engines.
如果使用DIV+CSS布局基本上不会存在这样的问题,从技术角度来说,DIV+CSS在控制样式时也不需要过多的嵌套,XHTML在控制样式时不需要过多的嵌套。
If you use div + CSS layout, there will basically be no such problem. From a technical point of view, div + CSS does not need too much nesting when controlling styles, and XHTML does not need too much nesting when controlling styles.

三、网页的速度
3、 Web page speed
使用了DIV+CSS布局的网页较Table布局减少了页面代码,浏览加载速度得到很大的提高;
The web page with div + CSS layout reduces the page code compared with table layout, and the browsing and loading speed is greatly improved;
四、SEO搜索引擎优化
4、 Seo search engine optimization
采用div-css设计的网站对于搜索引擎非常友好,很容能取得很好的排名,采用DIV+CSS避免了Table嵌套层次太多无法被搜索引擎抓取的问题;而且简洁、结构化的代码更加有利于突出和适合搜索引擎抓取。
The website designed with DIV CSS is very friendly to the search engine and can achieve good ranking. Div + CSS avoids the problem that there are too many nested levels of tables and can not be captured by the search engine; Moreover, the concise and structured code is more conducive to highlight the key points and suitable for search engine capture.
五、定位更准确
5、 More accurate positioning
div的代码的宽、高等都使用css或者页面的style来控制,也就是说在需要修改一个框的大小、位置时候,可以直接修改css的代码或者该标签的style代码即可实现,几乎不用修改其他代码,而且div可以精确的定位于网页的某一个地方,这点table是做不到的;
The width and height of div code are controlled by CSS or the style of the page, that is, when it is necessary to modify the size and position of a box, you can directly modify the CSS code or the style code of the label without modifying other codes. Moreover, div can be accurately located in a certain place of the web page, which table cannot do;
使用table的情况下,则可能会因为table的位置出现变动,有的时候不能精确的定位于网页的某一个地方,而影响到对整片代码的修改。
When using table, the location of the table may change, and sometimes it can not be accurately located in a certain place of the web page, which may affect the modification of the whole piece of code.
六、兼容性
6、 Compatibility
使用table布局,网页在不同浏览器的情况下就会发生错位,而DIV+CSS则不会,不论在什么浏览器下,网页都不会变形的
Using table layout, web pages will be misplaced in different browsers, while div + CSS will not. No matter what browser, web pages will not deform
