Making Animated Dropdown Menu by Using Pure CSS Li

问题:

I'm working with my own project to build a stylesheet(CSS) as what bootstrap does. However, I try to use only PURE CSS - no javascript or jquery even flash to do that.

Now, I'm having trouble with the Animated Menu Dropdown when small resizing as what mobile version looks like.

What I want is:

First, When the browser resize less then 768 and 480 or (55%), the animated circle menu appears, animating and Menu is hidden. After that, on hover (<div class="acn-menu"></div>), the animated circle menu runs again. When user click or touch the animated circle menu, the animated circle menu stops and the dropdown menu appears and push the content below it with no scrollbar at the same time as the animated circle rolls back and stops.

Second, How to be compatible with all browsers (even, in IE).

Here's what I have done more than a week: (Sorry for my bad English): I have just uploaded the sample in this site below:

Animated menu

When the browser resize less then 768 and 480 or (55%), the animated circle menu appears

This i have done with a media query in css: @media screen and (max-width:768px) and setting an animation:

After that, on hover (), the animated circle menu runs again.

This is done with an transform: rotate(180deg); inside an :hover statement.

When user click or touch the animated circle menu, the animated circle menu stops and the dropdown menu appears and push the content below it with no scrollbar at the same time as the animated circle rolls back and stops.

The click is done with an input type="checkbox" element. This is for a special css pseudo selector :checked. This lets us change the style of an :checked. What we do is combine it with an sibling selector so #input:checked ~ .sibling. Now we can style .sibling while we click on the checkbox. In addition to this added a label for the checkbox. label for="#ID" And hide the actual checkbox with display:none;

Rolling back the circle is done with transform: rotate(180deg);.

Browser support should be ok but, I haven't added all the prefixes for all the transforms and animations.

Transition and animation is CSS3 so IE9 doesn't support it.
Should work in IE10 and above.(probably missing -ms- prefixes)
Tested in Chrome 40.0.
