Direct answer
Using Edwin Martin’s jQuery plugin for shadow animation, which extends the .animate
method, you can simply use the normal syntax with “boxShadow” and every facet of that – color, the x- and y-offset, the blur-radius and spread-radius – gets animated. It includes multiple shadow support.
$(element).animate({
boxShadow: "0px 0px 5px 3px hsla(100, 70%, 60%, 0.8)"
});
Using CSS animations instead
jQuery animates by changing the style
property of DOM elements, which can cause surprises with specificity and moves style information out of your stylesheets.
I can’t find browser support stats for CSS shadow animation, but you might consider using jQuery to apply an animation-based class instead of handling the animation directly. For example, you can define a box-shadow animation in your stylesheet:
@keyframes shadowPulse {
0% {
box-shadow: 0px 0px 10px 0px hsla(0, 0%, 0%, 1);
}
100% {
box-shadow: 0px 0px 5px 0px hsla(0, 0%, 0%, 0);
}
}
.shadow-pulse {
animation-name: shadowPulse;
animation-duration: 1.5s;
animation-iteration-count: 1;
animation-timing-function: linear;
}
You can then use the native animationend
event to synchronise the end of the animation with what you were doing in your JS code:
$(element).addClass('shadow-pulse');
$(element).on('animationend', function(){
$(element).removeClass('shadow-pulse');
// do something else...
});
