Create a class called something like “subheader” and put in the attributes you want it to have. Like this:
#lowerheader {
background: #c0c0c0;
border-bottom: double 3px #000;
border-left: solid 1px #000;
border-right: solid 1px #000;
border-top: solid 1px #000;
text-align: center;
font: italic normal 75% 'Times New Roman', Times, serif;
letter-spacing: 0.1em;
padding: 15px 60px 15px 60px;
margin-left: 13em;
margin-top: 0;
margin-right: 13em;
}
Then after your header in your main template page, put in the text.
<h2 id="lowerheader"><?php bloginfo('description'); ?></h2>
Will return your tagline as the text. Of course, you could also just put whatever text you want to include.
<h2 id="lowerheader">Your Text Here</h2>
