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, so I'll be doing whatever routine stuff until some new images get uploaded or I find some new area to fiddle with.

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. 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.

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 ), and copy the following line into a javascript console:

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.

and JS and the bottom:

pageLoaded

Other stuff:

1: Load section content from the api. Assumes simple Title <h2 id="...etc...

API action=query&prop=sectioncontent returns [h2.id, section html] JS:

var sectionLoaded = {};

function toggleSection( header ) { header.className = header.className ? '' : 'expanded'; if( !sectionLoaded[ header.id ] ) { header.parentNode.insertBefore( document.createElement("div"), header.nextSibling ) .appendChild( document.createElement("img") ) .src = "loading.png"; // not a real file // Alternatively: // .appendChild( document.createTextNode("Loading...") ); requestSection( header.id ) }	window.updateFooterScroll && updateFooterScroll; }

function requestSection( id, isAnchor ) { sectionLoaded[ id ] = true; var xmlHttp = window.XMLHttpRequest ? new XMLHttpRequest : new ActiveXObject( 'Microsoft.XMLHTTP' ); xmlHttp.onreadystatechange = function { if ( xmlHttp.readyState == 4 && xmlHttp.status == 200 ) { var response = (window.JSON && JSON.parse ? JSON.parse : eval)( xmlHttp.responseText ); if(!response || response.length === 0) { return; }			var h = document.getElementById( response[0] ); if( h && h.nodeName == "H2" ){ if( isAnchor ) { h.className = 'expanded'; h = h.parentNode.insertBefore( document.createElement("div"), h.nextSibling); h.innerHTML = response[1]; var a = document.getElementById( id ); a && a.scrollIntoView; } else { h = h.nextSibling; h.innerHTML = response[1]; }				sectionLoaded[ response[0] ] = true; window.updateFooterScroll && updateFooterScroll; }		}	}	xmlHttp.open( 'GET', apiUrl + '?action=query&titles='+wgPageName+'&format=json&prop=sectioncontent&sectionid='+id, true ); // mw escapes ids automatically, so no need to worry afaik xmlHttp.send; }

function revealForHash( hash ) { var node = document.getElementById( hash = hash.substr(1) ); if( node ) { for(node && node.nodeName != "H2" ; node = node.previousSibling ) { while( node && !node.previousSibling ) { node = node.parentNode; }		}		if( node && node.className != 'expanded' ) { toggleSection( node ); }	} else { sectionLoaded[ hash ] || requestSection( hash, true ); } }

2: Login screen styles:

label { display: block; font-weight: bold; font-size: 13px; margin: 4px; }	border: #7E7E7E solid 1px; height: 26px; width: 217px; padding: 0px 5px; box-shadow: 0px 3px 5px #BBB inset; margin-left: 13px; margin-bottom: 5px; }
 * 1) mw-login-username, #mw-login-password {

<form style="padding: 10px;"> <label for="mw-login-username">Username: <input id="mw-login-username" /> <label for="mw-login-password">Password: <input id="mw-login-password" /> <input type="submit" style="line-height:1em;display:block;padding:9px 7px;color:white;font-size:14px;font-weight:bold;border:#545454 solid 1px;border-radius:3px;margin-top: 15px;background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#5277C7), color-stop(19%,#4C72C5), color-stop(72%,#315DBE), color-stop(100%,#2756BB)); background: -webkit-linear-gradient(top, #5277C7 0%,#4C72C5 19%,#315DBE 72%,#2756BB 100%)" value="Login ►" />

3: Search box stretches to max width on focus:

CSS:

-webkit-transition: width 1s,max-width 1s,color 1s,right 1s; } .searchfocused #mw-logo, .searchfocused #mw-you { width: 5px; max-width: 0px; } .searchfocused #mw-logo a, .searchfocused #mw-you a { width: 0px; color: transparent; } .searchfocused #mw-searchbutton { right: 20px; }	left: 8px; right: 16px; }
 * 1) mw-searchbutton, #mw-logo, #mw-you, #mw-logo a, #mw-you a {
 * 1) mw-results {

JS: (in document.onclick) -		search.onblur = closeSlider; +		document.body.className="searchfocused"; +		search.onblur = function{ +			closeSlider; +			document.body.className=""; +		};
