How to know the right DTD to use in my site? I’m trying to improve my new site (in CSS) applying some Jquery effects, and I found a article that says this:

“DOCTYPES are a key component of compliant web pages: your markup and CSS won’t validate without them. It is also essential to proper rendering and functioning of web documents in compliant browsers like Mozilla, IE5/Mac and IE6/Win.“

For those that are interested in the article, the link is this: http://www.alistapart.com/articles/doctype

This gay (Zelman) is great! He offers a list of the DOCTYPES that really works and it is because of this list I have doubts. What is the difference between XHTML STRICT – TRANSITIONAL OR FRAMESET?


I never notice to this line. I thought that if you apply CSS, then you change de DOCTYPE to XHTML, in contrary way, you just need to put HTML strict or transitional.

The article was nice ... on DTD I used it in my site ..
