Any idea to make my html page look better?
===

I create a web page to control my TV (See the figure below). When I click the button, the server receives the POST request and translates it to IR signals.

It works. But the UI looks ugly. I'm newbie of the web front-end. Is there any CSS library can make the buttons look better, or and some dynamic appearance with JS library?

BTW, the web server is hosted on Arduino, which has 2K memory, 16MHz CPU and 30k flash. So there isn't enough memory to save the internal CSS. I want the html page as small as possible. What I'm looking for is the CSS which I can link.
