Don't mix up html, css and javascript. Put the css and javascript into separate files and externally reference them from the html files, this will:

• clean up your html files

• allow the browser to cache the css and javascript so the files don't have to be re-downloaded for each page visit in your site

Don't use ` elements if you don't want to link something:

Talk

Instead, I'd suggest to link to /talk/, or, if that is not reasonable, use the tag. Links to #` are to use when you want to link to the top of the current page.
