<p>Is it possible to create, for instance, a box model hack while using in-line CSS?</p>

<p>For example:</p>

<p><code>&lt;div id="blah" style="padding: 5px; margin: 5px; width: 30px; /*IE5-6 Equivalent here*/"&gt;</code></p>

<p>Thanks! </p>

The most appropriate answer is
don't
. (Edit: to be clear, I mean don't do it inline, I don't mean don't use CSS hacks.)
Edit: This doesn't work, IE ignores the conditional comment. Leaving the answer here to not be a bastard.
The next most appropriate answer is conditional comments:
```
```
<div id="blah" style="padding: 5px; margin: 5px; width: 30px; <!--[if lte IE 6]> ... <![endif]-->">
```
```
