I stated earlier that the doctype needs to be the very first thing in your HTML documents. Well, that is in fact a slightly simplified version of the truth. There is also the XML declaration to consider. This is called an XML Declaration, and when it is present it needs to be inserted before the doctype.
Internet Explorer version 6 has a problem with that—this causes it to switch into Quirks mode, and as I explained earlier you most likely do not want that. The probability of all that happening all at once is quite slim, so the easiest way to solve the Internet Explorer problem is to simply omit the XML declaration. Always include one of the doctypes mentioned here as the very first thing in all of your HTML documents. It will make sure that validators know what version of HTML you are using, so they can correctly report any mistakes you have made.
It will also make sure that all recent web browsers use their Standards mode, which will give you more consistent results when you are styling the document with CSS. Jump to: navigation , search.
