In the first of what I am sure will be many posts regarding HTML, I would like to bid farewell to my old friends <B> and <I>.
Some people may think that the proper usage is to replace <B> with <strong> and <I> with <em>. In most cases that is correct, but not for the reason they are thinking. Although many browsers default to displaying <strong> as bold text, the reason to use <strong> over <B> is that semantically you are marking that bit of data as important. The same is true with <em>, you are trying to emphasize that bit of data so you surround it with the <em> element.
You should not rely on the browser's default for styling these two elements. Proper use of CSS will ensure that these two tags appear the way you want them to, but that is a CSS discussion. Remember, HTML should only contain data. HTML is not the place for style or functionality.
