When a CSS animation is applied from the beginning of the page load, things are easy. You just use the animation property with appropriate parameters, and you’re done. However, what if the animation is applied on a certain state, e.g. :hover, :active, :focus or a JS-triggered class change? A naïve approach would be to try […]
For some reason, I seem to have a fascination with CSS loaders these days. After recreating the Google loader with clean CSS recently, I set off to recreate the classic spinner with CSS. Yes, I know this has been done zillions of times, but I wanted a clean, maintainable, reusable solution, not just a proof […]
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 […]
This is a very quick tip, about a pet peeve of mine in almost every CSS animation I see. As you may know, I’m a sucker for reducing the amount of code (as long as it remains human readable of course). I demonstrated a very similar example in my “CSS in the 4th dimension” talk, […]
¿What’s the animation-direction property?
¿Is alternate reverse and reverse alternate (either would be allowed) a better value for animation-direction over alternate-reverse?
¿If so, should redundant combinations of normal with alternate or reverse also be allowed, such as normal alternate?
¿Or maybe we should ditch it altogether and replace it with animation-reverse, accepting values of none, all, even, odd?
It all started a few months ago, when Chris Coyier casually asked me how would I move an element along a circle, without of course rotating the element itself. If I recall correctly, his solution was to use multiple keyframes, for various points on a circle’s circumference, approximating it. I couldn’t think of anything better […]
A while ago, I posted about how to use steps() as an easing function to create a typing animation that degrades gracefully. Today I decided to simplify it a bit and make it more flexible, at the cost of browser support. The new version fully works in Firefox 1+ and IE10, since Opera and WebKit […]
What kind of transitions can you create with only one property? This is what my new experiment, animatable aims to explore. It’s essentially a gallery of basic transitions. It aims to show how different animatable properties look when they transition and to broaden our horizons about which properties can be animated. Hover over the demos […]
steps() is a relatively new addition to the CSS3 animations module. Instead of interpolating the values smoothly, it allows us to define the number of “frames” precisely. So I used it to create headers that have the well-known animated “typing effect”: As you can see, the number of characters is hardcoded in the steps() function, […]
