Note that we’ve offset the parent and pseudo element’s animations with a delay to tell the box that hides our text to reveal it only after the element itself has fully scaled into view. Finally, string together the animations, using either the timing functions or delays to offset each. Next, we'll use a pseudo element to mask our parent, setting the transform origin to the opposing option. Since we want the element hidden initially, we’ll use a scale transform along the appropriate axis to shrink it. We’ll also define a transform origin, in the case of the parent element we want to use the starting position. In text cases it’s best to allow automatic height and width, although a bit of padding doesn’t hurt. It’s a concept that might seem tricky but really relies on just a few things.įirst, we’ll set up our element positioning ( download the full code here) – define it as relative (only static will fail in this case). You’ve seen this before: a block of colour 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.
The big revealĪnimated content reveal effects have proved popular, and used properly they can capture user focus and engage your audience. This creates a nice, eye-catching effect. We now have a card that turns to face our mouse while the sheen effect moves in the opposite direction on top. Lastly, we set these offset values to our CSS variable properties, and the browser's renderer does the rest. We multiply this number by 800 as we want it to scale up to a maximum of 400px, which is how far we set the sheen pseudo-element outside the card. To achieve this we create a number between -0.5 and 0.5 that changes in the opposite direction by calculating the ratio by -1. Our pseudo-element looks best when it moves in the opposite direction to the mouse.
It's a great effect to start with because very little HTML is needed: įirst, we position the demo and set perspective for our 3D transform. It could be useful when you want to draw attention to an element on your page. This is a fun CSS effect that follows your mouse around.
