CSS animation is an incredibly useful and powerful tool. It can add interest or creative excitement, direct the user's eye, explain something quickly and succinctly, and improve usability. For that reason, recent years have seen more and more animation on sites and in app.

What is CSS animation?

CSS animation is a method of animating certain HTML elements without having to use processor and memory-hungry JavaScript or Flash. There's no limit to the number or frequency of CSS properties that can be changed. CSS animations are initiated by specifying keyframes for the animation: these keyframes contain the styles that the element will have.

Animated content reveal effects seem to be quite popular right now, and used properly they can capture user focus and engage your audience. You’ve seen this before: a block of  color grows from one side or another horizontally or vertically, and then retreats to the opposing side, this time revealing some text or an image beneath. It’s a concept that might seem tricky but really relies on just a few things.

With CSS3 transitions you have the potential to alter the appearance and behavior of an element whenever a state change occurs, such as when it is hovered over, focused on, active, or targeted.

Animations within CSS3 allow the appearance and behavior of an element to be altered in multiple keyframes. Transitions provide a change from one state to another, while animations can set multiple points of transition upon different keyframes.

Transitions

As mentioned, for a transition to take place, an element must have a change in state, and different styles must be identified for each state. The easiest way for determining styles for different states is by using the :hover, :focus, :active, and :target pseudo-classes.

Animations Keyframes

o set multiple points at which an element should undergo a transition, use the @keyframes rule. The @keyframes rule includes the animation name, any animation breakpoints, and the properties intended to be animated.

Clip-path

The clip-path property in CSS allows you to specify a specific region of an element to display, rather than showing the complete area

Using clip-path with CSS Shapes

The clip-path property is a great companion to the CSS Shapes properties, particularly the shape-outside property.

Using shape-outside you can change the way content flows around an element because the shape applied using shape-outside changes the geometry of the element’s float area. However, the shape does not change anything else about the element, like backgrounds and borders and such. This means that any borders and background images will not adapt to the shape created on the element. So, even though the element’s float area changes, the content around the element may end up being on top of the element’s background image.
