Talking about the importance of structure from "DIV+CSS"

As we all know, web standards in the early days of China's dissemination, people use "div+css" to describe the Web standards, seems to be a bit of truth, according to the domestic web designer's coding level, it seems to use a div with CSS to replace the table layout.

But the people who have studied the Web standard for a while know that this is a misunderstanding, then some people put forward, abandon Div+css's argument, advocate Xhtml+css, because to use two languages to structure the Web page, but this name is also inaccurate, incomplete, Because only the XHTML1.0 standard and the CSS2.0 (CSS2.1) specification are mentioned.

In fact, the Web Standard is the Web standard, called the other is not right, he is the web development of some of the set of standards, xhtml,xml,css,dom,ecmascript, to develop these standards for better constraints, the Web platform (browser) developers, And we follow web standards development, also for their own sake, through the efforts of the public, forcing rogue developers to follow the uniform standards, reduce the difficulty of developers, so that our works better cross-platform, across the browser barriers (Ie,ff,opera, etc.), across the barriers to equipment (PCs, handheld devices, mobile phones, Printing equipment, etc.), across user barriers (color blindness, anomalous trichromatism, poor eyesight, physical disability, etc.).

Why follow Web standards for design and development? The previous paragraph has also been macro mentioned, Cross-platform unified in a standard, and ultimately reduce the difficulty of development. The concrete implementation certainly does not have a boss so great to join the standard cause, the businessman always according to the interest drive, is which interest drives them to apply the Web standard?

Less code and components, easy to maintain

Lower bandwidth requirements (more concise code) and lower cost.

more likely to be searched by search engines

Easy revision, no need to change page content

To provide a printed version without copying content

Improve the usability of the website.

When the end owner sees the code in the application Web Standard is very concise, there have been many never met Div, and then you show him, can be arbitrary revision, a variety of devices compatible, a variety of browser compatible, very good, the boss is very appreciative, so many benefits, we fully support the Web standards, and lead to the results, The Web Standard technical talent is hot, the application Web Standard development project increases, the development efficiency becomes the question, the development pattern is still groping, inside appears, in the Web standard application some wrong method, Div's abuse, class's abuse, the structure is messed up, The emphasis on CSS is much more than the emphasis on XHTML.
