title: How to center an element in the middle of the browser window?
body: <p>How can I place some HTML element (say, a <code>&lt;div&gt;</code>, for example) in the middle of a browser window (not page, not screen)? Not depending on browser window size, screen resolution, toolbar layout, etc. E.g. I want it to be in the middle of the <strong>browser window</strong>.</p>
