We present warning sub-sections summarized under each topic. Several pitfalls are so large as to warrant a topic of their own. These are some examples:
Accidentally closing </SCRIPT> tags within the script itself
Interpreting punctuation as tags
Quotes can be a problem
Hiding scripts from old browsers
Line breaks in document.write() methods
Browser detection for handling layers
The topic names (and hence their lexical order in this reference) are summarized in the See Also list.
