CSS Borders: Distance from Object Edge?

Question

Quick question. I was writing out some code and was curious if there is a way to add a border on a div that is 5px within the object - as in not on the actual edge of the di

Answer 1

I've never come across any property that resembles this, so I'd have to say, simply, 'no.'

But then I'd feel bad for that, so all I could really suggest is wrapping the div you wish to 'sew on' within another div and styling the parent with the same background-color to emulate the look you're after. Here's some css for a possible take:

.wrap {
    border-width: 0;
    background-color: #ffa;
    width: 50%;
    padding: 0.5em;
}

.wrap #panel {
    background-color: inherit;
    height: 6em;
    border: 5px dashed #f90;
    text-align: center;
}

And some html:

    

        
This panel should look kinda sewn-on.
    

And, finally, A JS Fiddle demo

Okay, having just rediscovered this answer (thanks to the up-voter!), I can, now, provide an actual CSS-only no-extraneous-elements solution, using box-shadow:

#panel {
    background-color: #ffa;
    height: 6em;
    border: 5px dashed #f90;
    text-align: center;
    width: 50%;
    margin: 30px auto 0 auto;
    box-shadow: 0 0 0 15px #ffa;
}​

JS Fiddle demo.

The fourth parameter is the key, it defines the, uh, 'spread' of the shadow (the third parameter defines the 'fuzziness'/'diffusion' which in this case is 0), using the same background-color as the element itself gives the illusion that the border is within the element, while it's actually a shadow of the element extending out from the element.
