Answer 3

I think you need to look at the Web Developer Toolkit and Firebug plugins. Between them you can do just about anything you need to do in terms of debugging html and css.

Answer 4

Firefox addon:

HTML Validator

W3C:

W3C Validator

Answer 5

Not sure what you're referring to specifically. If you're talking about W3C validation you can access the validator tool here.

If something isn't displaying right you could install firebug (Firefox addon) to see what's happening, though this is more of a CSS issue than html.

Without knowing the specifics of your problem it is hard to give more specific advice than that.

Answer 6

HI, You should use firebug for this will help to developer to know about error or mistake. and

http://validator.w3.org/ is also help to know mistakes and some software as dreamweaver and notepad++ will help.

Answer 7

If you're using Java on the server side, you can add the JTidy servlet to your web.xml to validate all HTML generated by your web application.
