title: Create a dimmed background on-click
body: <p>Hopefully not too vague. All I want to do is make the entire page go dim after clicking a link. I would imagine having <code>div style="height:100%; width=100%;"</code> with a high <code>z-index</code>. to cover the webpage. My question is toggling this div. I'm not sure what I should even use to accomplish this.</p>
