CSS3 Animation

• Safari 4.0: 11/06/2008
• Chrome 1.0: 02/09/2008
• Firefox 5: 20/04/2011
• IE 10: 09/2011

Example properties that can be animated

left, right, top, bottom, margin, border, padding, opacity
transform: rotate, rotateX, rotateY, rotateZ, translateX, translateY, translateZ, scale, skew
transform-style: preserve-3d, flat

Easing Function Overview: http://easings.net/

• animation-timing-function: ease
• animation-timing-function: ease-in
• animation-timing-function: ease-out
• animation-timing-function: ease-in-out
• animation-timing-function: linear
• animation-timing-function: cubic-bezier(0.1, 0.7, 1.0, 0.1)
• animation-timing-function: step-start
• animation-timing-function: step-stop
• animation-timing-function: steps(4, end)

animation: cubeanimation linear infinite 14s;

@keyframes cubeanimation {
    to { transform: rotateZ(1080deg) rotateX(360deg) rotateY(360deg); }
}

CSS3 2D transformation

• Safari 3.2: 13/11/2008
• Firefox 3.5: 30/06/2009
• Chrome 1.0: 02/09/2008
• Opera 10.5: 02/03/2010
• Internet Explorer 9: 09/2010

transform: rotate, translate, scale, skew

CSS3 3D transformation

• Safari 4.0: 11/06/2008
• Chrome: 28/08/2010
• IE 10: 09/2011
• Firefox: 27/10/2011

transform: rotateX, rotateY, rotateZ, translateX, translateY, translateZ

The transform-style CSS property determines if the children of the element are positioned in the 3D-space or are flattened in the plane of the element.

perspective( 500px );

To activate 3D space, an element needs perspective.

transform-style: preserve-3d;

3D transforms use the same transform property used for 2D transforms.

• rotateX( angle )
• rotateY( angle )
• rotateZ( angle )
• translateZ( tz )
• scaleZ( sz )

Example 01 - Move tile

helper.js changes begin and end css class.

#slide1 {
 // transition goes here
}

#slide1.begin {
  left: 350px;
  top: 50px;
}

#slide1.end {
 left: 50px;
 top: 50px;
}

Add your first transition

transition: 500ms ease-out;
transition-property: all;

Try different transitions and build your own

transition-timing-function: cubic-bezier(0.86,0.22,0.12,0.59);
transition-duration: 500ms;
transition-property: all;

Example 02

#tile.begin { left: 20px; top: 20px; } 
#tile.end { left: 220px; top; 220px; }

Example 03

#tile.begin { left: 20px; top: 20px; } 
#tile.end { left: 220px; top; 220px; }

Example 04

#tile.begin { left: 20px; top: 20px; } 
#tile.end { left: 220px; top; 220px; }

Example 05 - Walking Character

.character {
    transform: translateX( 1044px );
    transition: transform 12s linear;
    animation: walk 1s steps(12) infinite;
}

@keyframes walk {
    from { background-position: 0px; }
    to { background-position: -1044px; }
}

Example 06 - Rotating Cube

.stage {
    perspective: 500px;
}

.cube {
    transform-style: preserve-3d;
    animation: cubeanimation linear infinite 14s;
}

figure {
    transition: 0.5s linear;
}

.front  { transform: translateZ(  150px ) }
.back   { transform: translateZ( -150px ) }
.left   { transform: translateX( -150px ) rotateY(	 -90deg ); }
.right  { transform: translateX(  150px ) rotateY(	  90deg ); }
.top    { transform: translateY( -150px ) rotateX(	 -90deg ); }
.bottom { transform: translateY(  150px ) rotateX(	  90deg ); }

@keyframes cubeanimation {
    to { transform: rotateZ(1080deg) rotateX(360deg) rotateY(360deg); }
}

Example 07 - Carousel

.stage {
    perspective: 1100px;
}

.carousel {
    transform: translateZ( -412px );
    transform-style: preserve-3d;
    transition: transform 1s;
}

figure:nth-child(1) {
    transform: rotateY(   0deg ) translateZ( 412px );
}

Math.round( ( 300 / 2 ) / Math.tan( Math.PI / 9 ) ) = 412;
