Query style menu with CSS3 : 제이쿼리 스타일 스타일시트 메뉴바, 네비게이션바

Query style menu with CSS3

Here’s a quick experiment I did with CSS3. Again I was just mucking about with CSS3 transitions which could one day replace all the fancy jQuery animation tricks people use. The outcome was a really simple animated sliding verticle menu.

If you want to view the demo you’ll need the lastest Safari version or even better go get the latest nightly build of webkit. This might even work in Chrome but I haven’t checked it. Oddly enough it didn’t seem to like it on OSX Tiger in Coda but in Leopard it was fine? This is all a long way off anyway but good fun to play with!

Menu Demo

First off in the demo you might notice the gradient which is CSS too. Really easy to do that with this….

body { background: -webkit-gradient
           (linear, left top, left bottom, from(#ccc), to(#fff));
}

Now we’ll style the un-order list with some padding and a background image to create a ridge like effect that our menu items will appear out of. The cool thing about this is by using -webkit-background-size’ the image is stretched if you add more items to it making the whole thing a bit more dynamic.

ul#nav {
    list-style: none;
    display: block;
    width: 200px;
    position: relative;
    top: 100px;
    left: 100px;
    padding: 60px 0 60px 0;
    background: url(shad2.png) no-repeat;
    -webkit-background-size: 50% 100%;
}

Everything else is pretty bog standard really. A simple un-ordered list and that’s about it. The styling for the list item anchor tags is where it all happens. The addition of the ‘-webkit-transition:’is going to allow us to animate to the ‘:hover’ state.

ul#nav li a {
    -webkit-transition: all 0.3s ease-out;
}

It says ‘all’ animatable properties should animate over 300ms using ‘ease-out’, similar to jQuerys easing functions.

Next we’ll add the styling for the anchor tags with some fancy -webkit-border-radius and -webkit-box-shadow to give it some shape and depth and complete it with a backgroung image for each item to enhance our interface effect, making them look like their coming from underneath the ridge.

ul#nav li a {
    -webkit-transition: all 0.3s ease-out;
    background: #cbcbcb url(border.png) no-repeat;
    color: #174867;
    padding: 7px 15px 7px 15px;
    -webkit-border-top-right-radius: 10px;
    -webkit-border-bottom-right-radius: 10px;
    width: 100px;
    display: block;
    text-decoration: none;
    -webkit-box-shadow: 2px 2px 4px #888;
}

The properties we’re going to style are color, background-color and left-padding so let’s add them to the hover: state.

ul.nav li a:hover {
    background: #ebebeb url(border.png) no-repeat;
    color: #67a5cd;
    padding: 7px 15px 7px 30px;
}

That’s about it really. No javascript and exactly the same effect. Probably be easy to make this degrade nicely for “certain” browsers. Now all you have to do is wait!
