CAUTION

 Don’t use headings to display text in boldface type or to make   certain parts of your page stand out more. Although the result might look cool in your browser, you don’t know what it’ll look like when other people use their browsers to read your page. Other browsers might number headings or format them in a manner that you don’t expect.

Tools to create searchable indexes of web pages might extract your headings to indicate the important parts of a page. By using headings for something other than an actual heading, you might be foiling those search programs and creating strange results.
