The table summary attribute should be used to describe
the table structure. It is very helpful for people using
non-visual browsers. The scope and headers attributes for
table cells are useful for specifying which headers apply
to each table cell, enabling non-visual browsers to provide
a meaningful context for each cell.

service for checking URLs for accessibility.

You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier maintain
compared with using <FONT> elements.
