Highlight one cell in a table, using a colored border and blinking text. In this case, create an ID rule such as this one:
#topartist { border: 3px solid #990000; text-decoration: blink; }
<TD ID=topartist>Johnny Cash</TD>
The ID rule can be used with only one type of element on a page.
The CSS rules look like this when combined at the top of the page:
<STYLE TYPE=text/css>
<!--
TD { background-color: #ffe4c4; }
.newfont { font-family: impact; }
#topsong { border: 3px solid #990000; text-decoration: blink; }
-->
</STYLE>
