Why does HTML Validator require closing tags for “dt” and “dd”?
In CSE HTML Validator Professional v4.51, AI Internet Solutions decided to require closing tags for the “dt” and “dd” elements. This is to help developers generate better HTML that is more compatible with XHTML and that is more trouble free. Furthermore, there has been a report that closing these tags may fix some display problems in the Opera browser. If, however, you want to change this back to optional closing tags, then you can do so using the Configuration Editor. Go to the Configuration Editor, Tag Names tab. Select dd (023) in the Tag Name Being Configured drop down list. Select the Optional closing tag radio button. Do the same for dt (022) and save the configuration.
