Web Browser Zoom: Design consequences

There are two different zoom modes.

Font zoom, this resizes the font size and all elements that are coupled with it.

Full page zoom, resizes the whole page and all elements. Only supported in modern browsers.

In your case I believe it's the font zoom that affects all sizes given in em. That means some elements on your page get resized and others not.

The simplest way around it is to give all dimensions in em instead of px, cm, pt.
