Help with theme development

You need to research html and css. The mods are going to tell you they don’t give support over this type of thing. Which is for good reason. Just go to W3c and research divs on the html and css side. You can always use Google too.

As a tip here is a simple example, but please research what I mentioned above.

<article class="post">
 <h2>Title</h2>
 <div class="datemeta">date by admin</div>
 <p>
 postbody
 </p>
</article>

.post {
 width: 100%;
 display block;
 background: #EEE;
 border-bottom: #CCC 1px dashed;
}

.datemeta {
 width: 100%;
 background: #333;
 display: block;
 margin: 5px 0;
 padding: 5px;
}

.post p {
 margin: 4px 0;
}

I’m not saying this is the answer. It is just an idea of what to look for and what to be thinking like. This is very over simplified.
