HTML tricks

When I write & in Code View in a URL, Dreamweaver MX replaces it with &. The solution is either to write %26 in the URL, or to edit the URL in Design View. In URLs, I can also use space = %20 (or +) =   and ? = %3F = ?.
The pre element does not work like verb or verbatim in TeX. The best way to include HTML code is to use Design View!
The id attribute may be used to create an anchor at the start tag of any element. Instead of <h2><a name="X">Y</a></h2>, I can write <h2 id="X">Y</h2>.
Use ° to get the degrees symbol, as in 10°.
