min-width on inline (not inline-block) behaving element

Question

I would like to set the min-width on a contenteditable div with some other elements next to it that must stay inline with the div.

Every solution I've seen uses inline-block, but I can't use inline-block behavior. When inline-block starts wrapping, it still behaves like a block element, and I need the div to behave as an inline element. I would imagine the solution would require more than just CSS, but it seems very difficult to set any event for when the div's text changes. A solution involving javascript and/or jQuery would be welcome.

EDIT: Here's a simplified version of what I'm trying to do. If the user would type more text than the page is wide, there is a difference in behavior between inline-block and block, and that's what I am concerned with.

<style type="text/css">
label {
    width: 40px;
    height: 40px;
}
#container {
    font-size: 32px;
}
#content {
    display: inline;
    min-height: 37px; /* doesn't work on inline elements */
    min-width: 80px; /* also doesn't work on inline elements */
}
</style>

<div id="container">
    <input type="radio" />
    <label>
        <span></span>
    </label>
    <span>(A)</span>
    <div id="content" contenteditable="true" unselectable="off">test</div>
</div>

Answer 1

Okay, here's the answer I came up with (in jQuery). Can anyone give me suggestions on leaving out some of these events that might not change the div's content or place a border around the div? (I'm also concerned with cut/paste).

$('#content').bind('blur focus load resize scroll click dblclick ' +
        'mousedown mouseup mousemove change ' +
        'select keydown keypress keyup', function () {
    if($(this).width() <= 80) {
        $(this).css("display", "inline-block");
    }
    else {
        $(this).css("display", "inline");
    }
})
