 1 | # Mega Nav in CSS
 2 | 
 3 | A simple mega nav menu in pure CSS.
 4 | 
 5 | 
 6 | ### Mega Wut?
 7 | 
 8 | Mega navs are an effective feature for large menu content and surprisingly easy to implement. If you've wanted to put one together but didn't know where to start, this quick walkthrough is for you.
 9 | 
10 | 
11 | ### How'd You Do It?
12 | 
13 | This implementation uses just CSS and nothing else. After creating a menu list, add `<div class="mega-menu">` to the menu item where the mega nav should display. The following `mega-menu` class will hide the menu:
14 | 
15 | ```css
16 | .mega-menu {
17 |   background: #fff;
18 |   border: 1px solid #ddd;
19 |   border-radius: 0 0 3px 3px;
20 |   opacity: 0;
21 |   position: absolute;
22 |   transition: all .3s ease .15s;
23 |   visibility: hidden;
24 |   width: 100%;
25 | }
26 | ```
27 | 
28 | The mega nav is hidden until you hover over the menu item:
29 | 
30 | ```css
31 | li:hover > .mega-menu {
32 |   opacity: 1;
33 |   overflow: visible;
34 |   visibility: visible;
35 | }
36 | ```
37 | 
38 | And voila...
39 | 
40 | ![Mega nav image 1](img/menu.png)
41 | 
42 | This implementation uses ARIA [landmark roles](http://www.w3.org/TR/wai-aria/roles#landmark_roles) following [WCAG 2.0](http://www.w3.org/TR/WCAG/) compliance for accessibility. Keyboard-only navigation isn't include.
43 | 
44 | 
45 | ### Support
46 | 
47 | Current versions of Chrome, Firefox, Safari, Opera, Edge, and IE8+.
