Loading... Effeckt.css. Minimal Monkey - Hello my name is Stephen Burgess. Using CSS3 transitions are great.
Supporting old browsers, not so great. As I stated in a tweet recently I think that for non-essential animations it’s fine to use CSS3 without a JavaScript fallback. If the user is viewing in an old browser like IE8, then stuff will just pop/snap without transitions. They still get to see all the content, we’re not depriving them of that, they just don’t get the nice transitions. Let’s take a simple image gallery like the one below. This gallery works great in modern browsers but when we remove CSS opacity and transition support there is an obvious issue – the user will continuously see the last image. The other fallback is to use a negative margin, e.g. margin-left: -99999px; That sort of works but in modern browsers there’s no fadeout transitions, or rather the transition happens, but off the page. It’s close but not as smooth as it could be by having the images crossfade. Flexible Google-style loader with CSS.
So, for a while I had noticed the nice sutble loader Google apps use and I was wondering if it would be easy to make with CSS and CSS animations: Yesterday, I realised that you can get this effect by increasing border size until about the middle of the element, as long as the total width stays the same (by using box-sizing: border-box): However, as you can see above, after the midpoint, the border is not curved any more, so does not produce the desired effect.
However, what if we split the background colour in half, and animated border-left until 50% of the width and then border-right from 50% of the width? That worked, but only gave us 25% of the effect. This is the finished result: The dimensions are all set in ems so that you can change the size in one place: Just change the font-size and the loader scales perfectly. And yes, it’s not super useful as-is, there are tons of spinners on the Web that you can use instead. Animatable: One property, two values, endless possiblities.

Generated content means pseudo elements added to the page via the ::before and ::after.
The support for applying transitions or animations to these in the current browser landscape is not great.

On mobile, on Safari on iOS 6.1 and down they didn't work, but they do on Safari on iOS 7. Why does this matter? Pseudo elements are really really useful. There is no reason that browsers shouldn't support this. Detect Pseudo-Element Animation Support. A while back I posted an interesting tidbit from Daniel Buchner which allows developers to detect DOM node insertions with JavaScript and CSS animations; an awesome trick driven by CSS animations.
Lea Verou recently posted another detection snippet driven by CSS animations: detecting pseudo-element animation support. Here's how she did it! The CSS The test case can use any pseudo-element; in this case we'll use :before: A simple color animation is assigned to the pseudo-element and a spot-check of generated content will tell you if animation is supported (green) or not (red). JavaScript Detection Thanks to a tip from Ahmed El Gabri, I can present a method to detect pseudo-element animation: var color = window.getComputedStyle( document.querySelector('.testElement'), ':before').getPropertyValue('color') if(color == 'rgb(0, 255, 0)') {} The same principal applies; if the color is green, the animation worked.
