Height of a div - css

Question

Height of a div
I'm trying to set the size of a div according to its content.
See the complete code here.
Basically my problem is in the div: content
In the HTML code look for the comment: wrongly
There had to add a tag p, I'm giving it a clear that the div align to the end.
Without this clear, the div will cut the image.
Actually I wonder just a better way to do this task.
There seemed a good a place p with nothing in it only with a clear class so that this problem does not happen.
What do you recommend me? There is a better way to do this task?
The goal is not to let the rope div content:
Html
<div id="header">
<div class="headerLeft" />
</div>
<div id="waycontact">
<div class="contactPaula">
<p>paulaMACHADO</p>
<p>crea 11111/D-MG</p>
<p>[phone]</p>
</div>
<div class="contactBeatriz">
<p>beatrizDAMAS</p>
<p>crea 22222/D-MG</p>
<p>[phone]</p>
</div>
<div class="address">
<p>av. xxxxxxxl, yyy, sl. zzz, centro - belo horizonte - mg</p>
<p>cep: 00000-000 - telefax: [phone]</p>
<p>xxxxx#yyyy.com.br</p>
</div>
</div>
<div id="content">
<img class="left" alt="Arquitetura" src="http://cdn.archdaily.net/wp-content/uploads/2009/05/1265154380_107-silos-090511-west-view-a4-allard-architecture-528x304.jpg" />

Answer 1

Add a "overflow:hidden;" to the div#content so it will look like the following. You won't need a separate clear property and a p tag. Good luck :)
div#content
{
margin:auto 40px;
width:200;
border:2px solid red;
overflow:hidden;
}

Answer 2

To make a container expand to fill floated elements, give it an overflow property:
div.wrapper {
overflow: auto;
}

Answer 3

A better method than using an empty <div class="clear"> is to use the 'cearfix' method.
This is an example borrowed straight from HTML5Bolierplate
, just apply it to the div that is giving you trouble.
In your case #content will become #content.clearfix
/* The Magnificent Clearfix: Updated to prevent margin-collapsing on child elements.
j.mp/bestclearfix */
.clearfix:before, .clearfix:after { content: "\0020"; display: block; height: 0; overflow: hidden; }
.clearfix:after { clear: both; }
/* Fix clearfix: blueprintcss.lighthouseapp.com/projects/15318/tickets/5-extra-margin-padding-bottom-of-page */
.clearfix { zoom: 1;
