Generic elements that can be addressed by CSS:
In conjunction with the id and class attributes div and span offer a generic mechanism for adding structure to documents.
Instead of using non-semantic mark-up such as <bold>to emphasize a word or phrase-use a heading. Consider the logic of where the heading lies in the document structure. Is it the most important piece of information that needs to be conveyed? 2nd? Then give it the appropriate heading of <h1> or <h2>.
