Question

Is there some way to keep a set width/height for a DIV, and pad the content without the DIV growing? See example below. I want all the boxes to be exactly 140×140.

HTML:

<div class="box1">Howdy.</div>
<div class="box2">Howdy.</div>
<div class="box3">Howdy.</div>​

CSS:

.box1 {
    width: 140px;
    height: 140px;
    background: #f66;
}

.box2 {
    width: 140px;
    height: 140px;
    background: #66f;
    padding: 1em;
}

.box3 {
    width: 140px;
    height: 140px;
    background: #6f6;
    border: 1em solid #000;
}

Answer 1

Yes you can use

-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box;    /* Firefox, other Gecko */
box-sizing: border-box;         /* Opera/IE 8+ */

to change the box model to make borders and padding internal to your width/height, but margins are still added.

and your updated Fiddle
