I know about html, css validation and some rules in pagespeed about css performance. Is there any all in one tool for checking? May be it can check some best practice for html markup.
It yells at me for not including `summary` attributes in my `<table>` tags. Why is that?

Have a look at The W3C QA Toolbox (for Markup, Links, CSS validation) and the popular YSlow Firefox extension, PageSpeed (another Firefox extension) and SpeedTracer (sort of like YSlow!, but for Google Chrome) which are more performance oriented.

Use this Html Validator 0.8.5.8 with firefox .
https://addons.mozilla.org/en-US/firefox/addon/249
It will show error and will give best suggestion
And this CodeBurner for Firefox 1.0 https://addons.mozilla.org/en-US/firefox/addon/13048
