CSS Float: Floating an image to the left of the text

Check out this sample: http://jsfiddle.net/Epgvc/1/

I just floated the title to the left and added a clear:both div to the bottom..

Just need to float both elements left:

.post-container{
    margin: 20px 20px 0 0;  
    border:5px solid #333;
}

.post-thumb img {
    float: left;
}

.post-content {
    float: left;
}

Edit: actually, you do not need the width, just float both left

I almost always just use overflow:hidden on my text-elements in those situations, it often works like a charm ;)

.post-container {
 margin: 20px 20px 0 0;
 border:5px solid #333;
}
.post-thumb img {
 float: left;
}
.post-content {
 overflow:hidden;
}

Is this what you're after?

• I changed your title into a h3 (header) tag, because it's a more semantic choice than using a div.

Live Demo #2 (with header at top, not sure if you wanted that)

HTML:

<div class="post-container">                
    <div class="post-thumb"><img src="http://dummyimage.com/200x200/f0f/fff" /></div>
    <div class="post-content">
        <h3 class="post-title">Post title</h3>
        <p>post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc post desc </p>
