Replace presentational tags with structural markup

You can use find and replace (and regular expressions), but the easiest way to do it might be to view your existing page in a browser and copy and paste the text from there into your HTML editor.

Think about the structure of your document! Merely replacing <b> tags with <strong> tags is not enough.

What is the most important header? Mark it up with an <h1> tag. Mark your subheads with <h2> tags and so on. Mark up paragraphs with <p> tags. Mark up your navigation as unordered lists.

Choose a DOCTYPE and use it. (We recommend XHTML transitional, unless you're hard core, in which case, go for it and use XHTML strict.)
