You can add a glow highlight effect - where the background briefly flashes yellow then returns to normal - to elements using CSS animations.

Click me to highlight!
@keyframes highlight {
 	0% {
 		background: #ffff99; /* lovely yellow colour */
 	}
 	100% {
 		background: none;
 	}
}

.highlight {
    animation: highlight 2s;
}

This is triggered by adding a class to the target element with Javascript:

document.getElementByID('highlightDemo').classList.add('highlight');

If you're targeting browsers which don't support animations, you'll need to use a support library such as jQuery UI which has a built-in highlight effect.
