Pulse loader ¶
Spécifications ¶
Creates a bouncing loader animation.
Creates a pulse effect loader animation using the animation-delay property.
-
Use @keyframes to define an animation at two points in the cycle. At the start (0%), the two <div> elements have no width or height and are positioned at the center. At the end (100%), both <div> elements have increased width and height, but their position is reset to 0.
-
Use opacity to transition from 1 to 0 when animating to give the <div> elements a disappearing effect as they expand.
-
Set a predefined width and height for the parent container, .ripple-loader and use position: relative to position its children.
-
Use animation-delay on the second <div> element, so that each element starts its animation at a different time.
