Style problem in the .entry-content class.

Hi!
Some time ago I have applied this special style for links in .entry-content:

.entry-content
a {
color: #FF0000;
text-decoration: underline;
}
.entry-content
a:hover {
text-decoration: underline;
color: #FF0000;
font-weight: bold;
}

But now I have found that this style doesn't work. What to do?
Thanks for your help!
