Ever-increasing specificity is how CSS works, to call that "emulating !important" is misleading. I'm suggesting using CSS as intended, the cascading part of cascading style sheets, instead of relying on a troublesome override.

Edit: Take this example:

    div {font-size: 60% !important;}

If I can't control the order the CSS is loaded, and I can't change that line directly, how do I modify it? Like this:

    html div {font-size: 70% !important;}

The use of !important isn't some simple way of bypassing ever-increasing specificity. In many cases it just makes things more complex.
