CSS Transitions, Transforms, Animations
- 1. CSS Transitions, Transforms & Animations Tuesday February 23, 2011
- 2. transitions
- 3. Ch-ch-ch-ch-changes Class .a arrow === css3 transition == ZOMG Class .b
- 4. What (are CSS3 transitions)? Sometimes we change CSS properties dynamically by changing or adding a class. e.g. $(‘input’).addClass(‘error’); CSS3 Transitions allow us to animate the change in these CSS properties… easily!
- 5. Transitions defined & browser support -browser-transition: {property} {duration} {easing} {delay}; easing defaults: linear, ease-in, ease-out, ease-in-out -webkit-transition: (Safari 3.1+, Chrome since forever) -moz-transition: (FF 4+) -o-transition: (Opera 10.doYouCare) -msie-transition: (apparently NOT ie9 )
- 6. animations
- 7. from { left: 100px; width: 100px; height: 100px; animation-timing: ease-in; } to { left: 200px; width: 50px; height: 50px; } keyframes but what’s going on in the middle? changing multiple styles at different times over an interval 7
- 8. keyframes (cont.) from { ... } to { transform: rotate(180deg); left: 200px; } 60% { left: 100px; } 30% { left: 200px; width: 50px; height: 50px; } 8
- 10. typeArg (string)
- 15. animationEnd
- 18. GPU vs. CPU hardware acceleration It’s the difference between... GPU’s are very good BitBLIT Operations 11
- 19. Animation Builders developers don’t want to code animations Banner Ads Purely Native Web Apps Native-Like Interfaces Immersive Sites (Sencha Animator) into the mainstream 12

- 24. transforms
- 25. transform: rotate(x) rotate(45deg) rotate(180deg) rotate(0deg)
- 26. transform: scale(x) scale(2) scale(1)
- 27. transform: translate(x, y) translate(0,0) translate(200px, 100px)
- 28. transform: skew(x, y) skewX(25deg) skewY(25deg) skew(0deg, 0deg)
- 29. transform: skew(x, y) 25° 25° skewX(25deg) skewY(25deg) skew(0deg, 0deg)
- 30. transform: skew(x, y) skew(25deg, 25deg) skew(0deg, 0deg)
- 31. transform: matrix(a,b,c,d,e,f) ???
- 32. transform: matrix(a,b,c,d,e,f) a ce bdf 0 0 1 = matrix(a,b,c,d,e,f) 3x3 matrix
- 33. transform: matrix(a,b,c,d,e,f) 1 0 0 0 1 0 0 0 1 = matrix(1,0,0,1,0,0) 3x3 matrix
- 34. transform: matrix(a,b,c,d,e,f) 2 0 0 0 2 0 0 0 1 = matrix(2,0,0,2,0,0) 3x3 matrix
- 35. transform: matrix(a,b,c,d,e,f) = matrix(2,0,0,2,0,0) scale(2)
- 36. transform: matrix(a,b,c,d,e,f) 1 0 tx 0 1 ty 0 0 1 sx 0 0 0 sy 0 0 0 1 scale translate 1 tan(a) 0 tan(a) 1 0 0 0 1 cos(a)-sin(a) 0 sin(a) cos(a) 0 0 0 1 rotate skew
- 37. transform: matrix(a,b,c,d,e,f) -1 0 0 0 1 0 0 0 1 1 0 0 0 -1 0 0 0 1 -1 0 0 0 -1 0 0 0 1 flip horizontal flip vertical flip both
- 38. transform-origin: x, y transform-origin: 50% 50% transform-origin: top left
- 39. Browser Support -moz-transform: rotate(45deg); // FF3.5+ -webkit-transform: rotate(45deg); // Saf3.1+, Chrome -o-transform: rotate(45deg); // Opera 10.5 -ms-transform: rotate(45deg); // IE9 transform: rotate(45deg); filter: progid:DXImageTransform.Microsoft.Matrix( M11=0.7071067811865476, M12=-0.7071067811865476, M21=0.7071067811865476, M22=0.7071067811865476, sizingMethod='auto expand'); // IE6 – IE9
