HTML - Not A Valid Doc Type, Please Help

Conflict between Mime Type and Document Type...

Morning - I have recently been learning CSS and have been upgrading my site to Semantically correct code. The first templat I am building is the following page

http://www.colletts.co.uk/colletts_n...ndexflash.html

and validates here

validates... sort of. Should I be worried about the mime type, what effect will this have on the page. If I follow the instructions and change the file extension to xhtml all hell breaks loose - http://www.colletts.co.uk/colletts_n...dexflash.xhtml IE Error - can't open thios document etc... What am I doing wrong???

Best,

Mas

Hi,

Currently my website is valid XHTML but I am planning on re coding the whole thing. I wanted to use HTML because to me it's a little easier and more basic. If I just start out with the html and head tags and no DOCTYPE and use the basic tags...do you think it would still work ok?

I just dont want to go through the whole validation thing. I know other sites who use plain HTML without validating and their site works fine. Also I was wondering if it matters about uppercase tags? like < HTML > and < A > or < a > does caps make any difference?

I guess I should probably just try it and then test it on major browsers to see for myself. Any advice would be appreciated! I just want to use plain HTML without worrying about validation....but I also want to make sure that people can use it on all different monitor sizes and browsers (at least all major browsers). I know thats the whole point of validation, but pretty much my question is: if I use plain HTML tags, including deprecated ones such as the < font > tag if it would still be usable on major browsers?

I'm wondering because I've noticed that even though the W3C claims they are deprecated, some of them still work anyways? Sometimes I wonder if the W3C is right about that?

Thanks!

Hi I am quite happy with my designed page and before I set about applying it to the whole site I wanted to Validate the Page - this is the first time I have set about validating a form and am at a loss - looking at W3's reccommendations I just got more confused

W3 Validator

Can anyone point me in the right direction to create an in page form that is Valid?

Cheers,

Ok I have used one of these social bookmarking generators to make links to add to del.icio.us and other sites but the links don't validate. Look:

HTML Code:

<ul>
  <li><a href="http://del.icio.us/post?url=http://johnsonsroofingllc.com&title=Johnsons Roofing LLC">del.icio.us</a> </li>
  <li><a href="http://myweb2.search.yahoo.com/myresults/bookmarklet?t=Johnsons Roofing LLC&u=http://johnsonsroofingllc.com">Yahoo MyWeb</a> </li>
  <li><a href="http://www.google.com/bookmarks/mark?op=edit&bkmk=http://johnsonsroofingllc.com&title=Johnsons Roofing LLC">Google</a> </li>
  <li><a href="http://www.stumbleupon.com/submit?url=http://johnsonsroofingllc.com&title=Johnsons Roofing LLC">StumbleUpon</a> </li>
</ul>

How do I make this valid?
