Awesome CSS3 animated header

You can now create stunning animations with CSS3. But, I bet you know that. The keyword when it comes about CSS3 animations is the CSS3 @keyframes rule and in this article you will learn how to create an awesome CSS3 animated header using it.

The HTML

The markup is minimal and quite self explanatory. Please, don’t blame me for divitis. :)

<div class="header">
    <div class="wrapper">
        <div class="christmas-tree tree1"></div>
        <div class="christmas-tree tree2"></div>
        <div class="christmas-tree tree3"></div>
        <div class="snowman"></div> 
        <div class="christmas-tree tree4"></div>
        <div class="christmas-tree tree5"></div>
        <div class="christmas-tree tree6"></div>
    </div>
</div>

The CSS

As you read at the beginning of this article, the @keyframes rule does all the magic. Also, to keep the following code as clean as possible, I will not add the prefixed versions too (-moz-, -webkit-, -ms-).

You can find the full CSS3 code when viewing page source for the demo.

Header background

To achieve the snow effect, you will need to animate the background-position property for the first .header background. As a quick note, for the browsers that do not support multiple backgrounds, the snow will not be visible for this example.

.header{
    margin: 0 0 30px;
    background: url(header-bg.png);
    background: url(snow-bg.png) repeat-y center, url(header-bg.png);
    animation: animate-snow 9s linear infinite;        
}

@keyframes animate-snow
{
    0% { background-position: center 0, 0 0;}
    100% { background-position: center 885px, 0 0;}
}

Header wrapper

The .wrapper element basically holds all our Christmas trees together with the snowman. Please note the position: relative declaration:

.wrapper{
    width: 960px;
    height: 315px;
    margin: auto;
    overflow: hidden;
    position: relative;
    background: url(wrapper-bg.png) no-repeat bottom;
}

Animated header example

For the Christmas trees, the animation-duration value was randomly changed in order to create a cool effect:

@keyframes animate-drop {   
    0% {opacity:0;transform: translate(0, -315px);}
    100% {opacity:1;transform: translate(0, 0);}
}   

.christmas-tree,
.snowman {
    position: absolute;
    animation: animate-drop 1s linear;
}

.christmas-tree {
    width: 112px;
    height: 137px;
    background: url(christmas-tree.png);
}

.snowman {
    width: 115px;
    height: 103px;
    top: 195px;
    left: 415px;
    background: url(snowman.png);
    animation-duration: .6s;
}   
    
.tree1 {
    top: 165px;
    left: 35px;
    animation-duration: .6s;       
}

.tree2 {
    left: 185px;
    top: 175px; 
    animation-duration: .9s;       
}

.tree3 {
    left: 340px;
    top: 125px; 
    animation-duration: .7s;       
}

.tree4 {
    left: 555px;
    top: 155px; 
    animation-duration: .8s;       
}

.tree5 {
    left: 710px;
    top: 170px; 
    animation-duration: .7s;       
}

.tree6 {
    left: 855px;
    top: 125px;
    animation-duration: .6s;       
}

Browser support

Here’s the support at this time: Firefox 5+, IE 10+, Chrome 6+, Safari 5+. For non-supported browsers, you don’t have to worry, everything will be just fine as long as you provide decent fallbacks.

Why to use animations?

Simple answer: to draw the user’s attention. Get inspired by another example, here is one of my previous articles, where I also used CSS3 keyframes: Cool notification messages with CSS3 & jQuery.
