Mobile full screen expand menu II

Author: Dynamic Drive

An alternate rendition of Mobile full screen menu, this one uses CSS3 scale() to collapse the full screen menu initially, expanding to fill the screen when expanded. It uses the popular CSS checkbox adjacent sibling technique to toggle the menu between open and closed when the drawer style toggler is clicked on. The menu works across all modern browsers and mobile devices, while in IE8, a more limited interface is presented that's at least functional for those users.

For the font this menu uses "Bitter", a Google custom font.

The CSS:

<link href="http://fonts.googleapis.com/css?family=Bitter&subset=latin" rel="stylesheet" type="text/css"> <style> body { /* webkit adjacent sibling bug fix: https://css-tricks.com/webkit-sibling-bug/ */ -webkit-animation: bugfix infinite 1s; } @-webkit-keyframes bugfix { from {padding:0;} to {padding:0;} } input[type="checkbox"]#togglebox { /* checkbox used to toggle menu state */ position: absolute; left: 0; top: 0; visibility: hidden; } label#navtoggler{ /* Main label icon to toggle menu state */ z-index: 9; display: block; position: relative; font-size: 8px; /* change font size to change label dimensions.

The HTML:
<div class="menuwrapper"> <input type="checkbox" id="togglebox" /> <label for="togglebox" id="navtoggler"></label> <nav id="expand-fullpagemenu"> <label for="togglebox" id="closex">Close</label> <ul> <li><a href="http://www.dynamicdrive.com">Home</a></li> <li><a href="http://www.dynamicdrive.com/new.htm">DHTML</a></li> <li><a href="http://www.dynamicdrive.com/style/">CSS Library</a></li> <li><a href="http://www.dynamicdrive.com/forums/">Help Forums</a></li> <li><a href="http://www.cssdrive.com">CSS Gallery</a></li> <li><a href="http://www.javascriptkit.com">JavaScript</a></li> <li><a href="http://www.cmsroundup.com">CMS Roundup</a></li> </ul> </nav> </div> <p> <a href="#" onClick="expandfullscreenmenu('open')">Arbitrary Open Menu link</a><br /> <a href="#" onClick="expandfullscreenmenu('close')">Arbitrary Close Menu link</a><br /> <a href="#" onClick="expandfullscreenmenu()">Arbitrary Toggle Menu link</a> </p>

Like version I, the menu comes with a companion JavaScript function that lets you toggle the state of the full screen menu beyond the built in interface, from anywhere on the page as you see fit. Just call the function:

expandfullscreenmenu(action)

with the "action" parameter being one of the following three choices: "open", "close", or empty. When called with no (or empty) parameter, the function will toggle the state of the full page menu. Here's an example:

<a href="#" onClick="expandfullscreenmenu()">Arbitrary Toggle Menu link</a>
