There are many ways of doing the same thing in html. For most of our cache pages we use the paragraph tag <p> </p>
<p> sample text </p>
You need to put the <p> at the beginning and </p> at the end of your paragraphs. If you want a blank row just put a <p></p> on the line you want blank or a <br> as other folks have mentioned.
Hope that helps.
