Why does marquee not conform to Web standards?

In the classic forum to see the Netizen Jeanjean20 mentioned marquee how to modify to meet the standard. I looked at the friends of the thread feel very good, moderator GREENGNN indicated that marquee is not in line with the standard has been discarded. Have a friend big dozen uneven say feel go to unreasonable, originally very good effect now changed. Also have a friend said go to good, look at bored. Everyone has their own understanding of the angle, but how we understand it is one thing, but we have to figure out why, here I greengnn the conclusion to revise and add some content, I hope you understand and can think.

The first thing to correct is: Marquee was abandoned by the "." This sentence is actually wrong, why, because marquee has never been regarded as a formal label use. The label has never been developed, and there is no "abandonment". It's like saying divorce before you get married. In fact, marquee, like many other labels, is privately made by companies such as Microsoft and Netscape, and the company has not recognized the label for a long time. This money company is unreasonable, but this unprofitable organization is better debater!

Why has the marquee not admitted to the Internet? To say that this label in the eyes of the vast number of Web designers is also a screwdriver Ah! In the early years, we thought of technical force as a conspicuous capital. But now do not claim to use (here to digression: Many people say that the limited use of the big, this is wrong, the people's rights limit you don't use or can not use. ), why do we have to be clear about what this standard is. Standards are not a technology, standards are just a specification and a proposition. We are still using the original HTML4.0 label, the standard does not add to our XHTML what label, but gives what is recommended to use (example: P,div,ul,dl,span,em ...), which is not used (example: Font,b,u,i ...), and advocated the semantics and the use of norms. Of course, the standard is not just XHTML but also includes CSS and DOM and scripting language. Many people think that CSS is the standard after the production, in fact, not, CSS is very early, the standard is the same as CSS, advocates do not use some browser manufacturers to develop some CSS, such as CSS filters.

In the standard there is also a very important point, that is functional separation. Divided into three parts of structure, style, and behavior, these three sections include, respectively, the structure (XHTML, XML), the sample (CSS), the behavior (DOM, ECMAScript). Here we come back to think about why the marquee was not recognized by the big-man, I think all of them should understand. He is no longer a structural label like the font and B tags. They have the style and behavior characteristics, and then draw them into the structure of the category is obviously more redundant. Anshan Dermatosis Hospital which good www.0412pfk.org

Therefore, we hope that the effect of marquee can be preserved or realized will need to pay more attention to JavaScript, scripting language must be able to get your Web page to move up. If you want to make the place you specify, it is important to focus on the ID and class used in the tag.
