CSS web page layout significance and side effect
Along with the WEB2.0 standardization design idea’s popularization, the many domestic large-scale open-door web sites already use the DIV+CSS manufacture method. From the practical application situation, this method is better than the method of using form to create web sites.
Now the majority of websites still use the way of form nesting content to manufacture the website. Although this method is quite familiar to us, It actually hinders one kind of website design method of better, more compatible, more nimble, moreover function more formidable, which is DIV+CSS.
The CSS web page layout’s significance manifests in the following aspect:
First, causes the page to load quickly.
Because the majority page codes are written in the CSS, it causes the page volume capacity becomes smaller. Relative to the form nesting way, DIV+CSS makes the page independent in more regions. When opening page, it loads stage by stage. It is not like the form nesting which circles the entire page in a big form, causing the load speed to be very slow.
Second, reduce the current capacity expense.
The page volume changes smaller. The browsing speed changes quicker. This causes the website controlling main engine current capacity to have the biggest superiority.
Third, make revising designs more effective.
Because of using the DIV+CSS manufacture method, when revising pages, it is easier and time-saving. According to the region content mark, it finds corresponding ID in CSS, which causes revising pages more convenient and also not to destroy other pages’ layout style.
Fourth, maintain visual uniform.
One of DIV+CSS most important superiority: maintain visual’s uniformity. The form nesting’s manufacture method will cause the show effect to the deviation between page and page, or between the region and region. DIV+CSS manufacture method uses CSS file to control all the pages, or all regions which has avoided the effect deviation between the different zones or the different pages.
Five, make web pages included well by the search engine.
Because the majority of HTML code and the content style have read in the CSS document, this causes in the homepage the textual material to be more prominent obviously, which is advantageous by search engine gathering including.
Sixth, have the affinity to web surfer and the browser. Because CSS contains rich style, it can make pages more flexible. It according to different browsers display can achieve the unity and no deformation of the show effect.
We say so many CSS layout significance and advantages, but also cannot despise CSS layout effects:
One, even for the web design expert it is also very easy to create problems, not mention the beginners.
Two, CSS web design elements are usually put in one external file, or several files. There may be quite complex, even if the CSS file is huge. So if the css files abnormal calls are abnormal, the whole website will become too horrible.
Third, although DIV+CSS solve most browsers’ compatibility problems, it also has abnormal in some browsers such as in Firefox browser.
Four, whether the DIV + CSS on search engine optimization, depends on the web design professional level, rather than DIV + CSS itself. DIV + CSS web design cannot guarantee to be helpful for search engine optimization, and even cannot guarantee to have more simple design code than HTML website, not mention that the search engine includes and ranks the websites not based on whether using the form and the CSS positioning. This is why many websites created by traditional form layout rank in the front of the search results, while many websites using CSS and web page standard still rank in the below.
Synthesizing the above discussion of DIV + CSS advantages and slightly, I think that we should not just follow the others. How to more effectively and more reasonability use WEB2.0 design standards takes a long time to learn and exercise. But how to use DIV+CSS better, I feel it needs practice and examination. After we accumulated the rich design experience, we can master well the skill.
