问题 I have a web page with two dropdowns. Selecting an option in one dropdown will update the list of options in the other dropdown through a script that's triggered by the blur event.

问题 Today I though I'd redesign my website and approach it from a different way. Instead of focusing on typography I though I'd just add a big image and little text. I simply done: html { background: url(../img/background.png) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; filter: blur(10px); -webkit-filter: blur(10px); -moz-filter: blur(10px); -o-filter: blur(10px); -ms-filter: blur(10px); } ..
