Athena/TopBarPrototype

So I was looking at [[Athena]], and that thing looks really cool, and I felt like fiddling with some css and js, so...

...fiddles with css and js...

...So now I've gotten as far as the pics at [[Athena]] let. I plan to try to maintain this and keep it up to date with
 whatever design documents and images get uploaded, as well as fiddle with it whenever I get an idea of my own. 

Summary of content: HTML, CSS, and JS for the top-bar, the bottom-bar, the "You" menu, and the footer. JS handles section 
expanding, the "sliding" of the top and bottom bars (with "locking" the bottom bar at the bottom of the page), search 
suggestions (with history suggestions), menu expanding. CSS also for non-signed-in-view. CSS background-images are limited 
to those uploaded by Jorm so far. No JS libraries used, assumed HTML is minimal. (Total JS 1.78Kb, CSS 1.7Kb)
Additional things at the bottom: JS for handling if there's ever a way to pull section content from the api based 
on an element's id in the page, and CSS and HTML for the login page.

I'm not in any position to be able to make this stuff go anywhere by myself (I don't know PHP, and don't have SVN access 
or whatever), but I'm going to keep fiddling with it anyway, even if it's probably useless. Meh.



So the CSS, HTML, and JS is below. If you want to sort of see what it looks like by viewing it on a desktop 
browser, go to a random mobile page (say, http://en.wikipedia.org/w/index.php?title=Zebra&useformat=mobile ), 
(make sure you're not using the "beta", you can use ?mobileaction=opt_out_mobile_site to opt-out) 
and copy the following line into a javascript console:


document.body.onmousedown=document.body.ontouchstart=window.onload=null;for(var i=0,h=document.getElementsByTagName('h2');i<h.length;i++){h[i].removeAttribute("onclick");h[i].removeAttribute("class")}document.body.innerHTML += '<style>#mw-top-bar{top:0px;height:45px;}#mw-bottom-bar{bottom:0px;height:40px;}#mw-top-bar,#mw-bottom-bar{position:fixed;width:100%;color:#FFFFFF;-webkit-transition:all 0.3s;border-spacing:0px;}#mw-top-bar,#bottom-bar-left,#bottom-bar-right{background:-webkit-gradient(linear,left top,left bottom,color-stop(0%,#3E3E3E),color-stop(14%,#393939),color-stop(32%,2E2E2E),color-stop(64%,#151515),color-stop(84%,#080808),color-stop(100%,#000000));background:-webkit-linear-gradient(top,#3E3E3E 0%,#393939 14%,#2E2E2E 32%,#151515 64%,#080808 84%,#010101 100%);background-color:#000000;}#mw-bottom-bar div{position:absolute;bottom:0px;font-size:10px;font-weight:bold;}#bottom-bar-left{left:0px;width:58px;height:45px;}#bottom-bar-center{background:-webkit-gradient(linear,left top,left bottom,color-stop(0%,#6D6D6D),color-stop(15%,#676767),color-stop(36%,#5A5A5A),color-stop(77%,#494949),color-stop(100%,#282828));background:-webkit-linear-gradient(top,#6D6D6D 0%,#676767 15%,#5A5A5A 36%,#494949 77%,#282828 100%);background-color:#6D6D6D;left:58px;right:112px;height:40px;box-shadow:0px -15px 15px #3A3A3A inset;-webkit-box-shadow:0px -15px 15px #3A3A3A inset;}#bottom-bar-right{right:0px;width:112px;height:45px;}#mw-bottom-bar.closed{bottom:-45px;}#mw-top-bar.closed{top:-50px;}#mw-you,#mw-logo,#mw-signin{font-size:10px;font-weight:bold;height:45px;width:63px;padding:0px;text-align:center;}#mw-logo a,#mw-bottom-bar span,#mw-interwiki,#mw-you a,#mw-signin a{display:block;color:#FFFFFF;height:15px;padding-top:30px;}#mw-bottom-bar a{float:right;width:50px;text-align:center;color:#FFFFFF;}#bottom-bar-center a{float:left;padding-top:22px;height:18px;}div #mw-interwiki{float:right;width:62px;}#mw-you,#mw-signin{height:15px;width:50px;padding-right:8px;padding-left:5px;}#mw-you.active div,#mw-signin div{background:-webkit-gradient(linear,left top,left bottom,color-stop(0%,#3964C0),color-stop(23%,#335FBE),color-stop(100%,#1044B5));background:-webkit-linear-gradient(top,#3964C0 0%,#335FBE 23%,#1044B5 100%);background-color:#3964C0;}#mw-you.active:after{position:absolute;right:28px;

Note that the "Languages" and "More" buttons won't work because I don't know what the menu is supposed to look like. 
Also, I didn't bother to duplicate the css prefixes for every major browser, so this will only work for Webkit browsers.
And of course, the links won't actually go to the correct pages.
