@keyframes at-rule

The @keyframes at-rule sets keyframes (waypoints) for an animation. A keyframe represents various properties of our CSS element, such as position, size, color, etc., that are applied to the element at a specified time.

Syntax

@keyframes animation name {
	keyframes
}

Example

Setting keyframes:

<div id="elem"></div>

@keyframes anim {
	from {
		margin-left: 0px;
	}
	to {
		margin-left: 400px;
	}
}

#elem {
	animation: anim 3s infinite;
	border: 1px solid black;
	width: 50px;
	height: 50px;
}

Example

Now let's move our square using animation from top to bottom:

<div id="elem"></div>

@keyframes anim {
	from {
		margin-top: 0%;
	}
	to {
		margin-top: 10%;
	}
}

#elem {
	animation: anim 2s infinite;
	border: 1px solid black;
	width: 50px;
	height: 50px;
}

Example

Let's increase the width of our shape using animation, setting key points in percentages:

<div id="elem"></div>

@keyframes anim {
	from {
		width: 10%;
	}
	to {
		width: 40%;
	}
}

#elem {
	animation: anim 2s infinite;
	border: 1px solid black;
	width: 50px;
	height: 50px;
}

Example

Now let's change a transparency of our shape:

<div id="elem"></div>

@keyframes anim {
	from {
		background-color: #467CBC;
	}
	to {
		background-color: #C2DDFD;
	}
}

#elem {
	animation: anim 2s infinite;
	border: 1px solid black;
	width: 50px;
	height: 50px;
}
