I'm trying to create a css reset that targets only my control. So the HTML will look something like this:

<body>
  <img class="outterImg" src="sadkitty.gif" />
  <div id="container" class="container">
    <img class="innerImg" src="sadkitty.gif" />
    <div class="subContainer">
      <img class="innerImg" src="sadkitty.gif" />
    </div>
  </div>
  <img class="outterImg" src="sadkitty.gif" />
</body>

The CSS is what I'm having trouble with, but I'm currently working with this:

img 
{
  // Bad style declarations for the entire page
  border: solid 3px red;  
  width: 50px;
}

.container img, .container div, .container etc.
{
  // Style reset for specific elements within my control "container"
  border: solid 3px blue;
  width: 100px;
}

.innerImg img
{
  // The target style for the specific class/element within the control
  border: solid 3px green;
  width: 200px;
}

The problem is that ".innerImg img" does not override ".container img" as I would expect. So, what would be the best method for resetting the style of all elements within the "container" element, and then placing styles on classes within that element?

A: 

I suspect this results in close to what you wanted.

img  
{  
  border: solid 3px red;  
  width: 50px;  
}  
.container .innerImg, .container div  
{  
  border: solid 3px blue;  
  width: 100px;  
}  
.container .subContainer  
{  
  border: none;  
}  
.subContainer .innerImg  
{  
  border: solid 3px green;  
  width: 200px;  
}

The selector .innerImg img refers to an img element inside an element with the class innerImg. There's nothing like that in your document.

What you probably want there is img.innerImg .

Beyond that, there is a short calculation for selector specificity that determine which rule is followed. (That link contains my new favorite qualifier in any document: "in a number system with a large base")
