CSS question

[pc]

There are few ways to accomplish this, but all is related and works the same way.
If your recips are just simple links then you can add a.class to a link like this

<a href="http://www.domain.tld" title="title" class="class">Title anchor</a>

and in the css file you just specify this class

a.class{
font-size:normal;
font-seight:400;
color:black
etc etc
}
a.class:hover{
font-size:normal;
font-seight:700;
color:red
etc etc
}

or you can specify certain div elements to behave differently like ex:

<div id="container"><a href="http://www.domain.tld" title="title">Title anchor</a></div>

#conatiner a{
font-size:normal;
font-seight:400;
color:black
etc etc
}
#conatiner a:hover{
font-size:normal;
font-seight:700;
color:red
etc etc
}

Make note that I used id to the div but most common practice and safe would be using classes. ID's could be additional elements inside of a class elements to specify dynamic actions ex using Jquery.

Usually if I don't know something regarding coding then Google is my friend , like this

Hope that helps.
