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

For each post box, I want the thumbnail to float to the left and the text to float to the right. I do not want the thumb to wrap around the text.

Here is my html code:

<div class="post-container">                
   <div class="post-thumb"><img src="thumb.jpg" /></div>
   <div class="post-title">Post title</div>
   <div class="post-content"><p>post description description description etc etc etc</p></div>
</div>

I've tried a few ways and still can't get it to work... the text won't show on the right...

Here's my CSS code:

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

.post-thumb img {
    float: left;
    clear:left;
}

.post-content {
    float:right;
}

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 #1
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>
   </div>
</div>

CSS:

.post-container {
    margin: 20px 20px 0 0;  
    border: 5px solid #333;
    overflow: auto
}
.post-thumb {
    float: left
}
.post-thumb img {
    display: block
}
.post-content {
    margin-left: 210px
}
.post-title {
    font-weight: bold;
    font-size: 200%
}

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
