It turned out to be like this, I added a padding and it became like this

I added a sentence

.archive-header p{float:left;padding: 15px 20px;}

The original code is like this:

		<header class="archive-header"> 			<h1><a href="http://192.168.1.148/?cat=5">2222</a></h1>			<p>42342342343</p></header>

I just want the subtitle at the back to be vertically aligned in the center. Could you please tell me how to change it?
