you can also define a custom css style for certain blocks of text, useful for headers and other areas that need to be eye catching.
for example:
body {
font-family:Verdana,Arial,Helvetica;
font-size:10px;
}
.blueBold {
font-weight:bold;
color:#003366;
}
so there i defined the default body text as the verdana family at size ten, then created a custom style for a header, making the text blue and bold.
then, you can call the .blueBold style at anytime in your html by using:
<span class="blueBold">My bold blue text is in here!</span>
hope that helps.
