Syntax:
transition: <property> || <duration> || <timing-function> || <delay> [, ...];
Note that the duration must come before the delay, if the latter is specified.
Individual transitions combined in shorthand declarations:
-webkit-transition: height 0.3s ease-out, opacity 0.3s ease 0.5s;
-moz-transition: height 0.3s ease-out, opacity 0.3s ease 0.5s;
-o-transition: height 0.3s ease-out, opacity 0.3s ease 0.5s;
transition: height 0.3s ease-out, opacity 0.3s ease 0.5s;
Or just transition them all:
-webkit-transition: all 0.3s ease-out;
-moz-transition: all 0.3s ease-out;
-o-transition: all 0.3s ease-out;
transition: all 0.3s ease-out;
Here is a straightforward example. Here is another one with the delay property.
Edit: previously listed here were the compatibilities and known issues regarding transition
. Removed for readability.
Bottom-line: just use it. The nature of this property is non-breaking for all applications and compatibility is now well above 94% globally.
