![]() Keep transitions and animations to only transform and opacity, and you’re certain to achieve the best possible performance, and with that, the best possible user experience. Why bother?Įven if your desktop likely handles animating box-shadow without any issues, your phone may not, and even your desktop may start to stutter when animating a more complex layout. That’s certainly a lot of CSS to achieve the same effect as simply animating box-shadow, just with improved performance. This is the critical difference between the two techniques, stripping out all of the other layout styles: We minimize the amount of repaints (and work that your browser has to do) by sticking to only changing these two properties during the animation. Why are we seeing this effect? There are very few CSS properties that can be animated without constantly triggering repaints for every frame, namely opacity and transform. There are clearly more re-paints when hovering the cards on the left side (animating box-shadow), compared to hovering the cards on the right side (which animate the opacity of their pseudo-element). ![]() To start, choose a color for the drop shadow and press OK. A new window will open where you can adjust the drop shadow's settings. Heres what the result will look like with. You can also choose Layer > Layer Style > Drop Shadow from the menu. And then I show you how to customize the effect by choosing a border and shadow color directly from the image itself. Find the Ellipse shape you created in the layer list and click the circle on the right side to select that shape. Then from the list of options, choose Drop Shadow, and you'll see different adjustments you can make. To do this, navigate to your Layers tab on the right side of the interface. If you bring up your developer tools and hover one of these items, you should see something similar to this (green bars are paints less is better): The first thing we need to do is make sure that our teal circle is selected. On the left we’re animating box-shadow on hover, and on the right we’re adding a pseudo-element with :after, applying the shadow to that, and animating the opacity of that element. The default settings in Figma are as follows: 0px 4px 4px rgba(0, 0, 0, 0. Follow for more Figma tips 0 AS IS in Figma. Let’s look at how you can do shadows the correct way. The only difference is how we apply and animate the shadow. The default (drop) shadow settings in Figma don’t really feel right. If the two examples look the same to you, that’s the point. Have a look at the demo and compare the two different techniques we’ll be exploring. There’s an easy way of mimicking the same effect, however, with minimal re-paints, that should let your animations run at a solid 60 FPS: animate the opacity of a pseudo-element. Animating a change of box-shadow will hurt performance. ![]() How do you animate the box-shadow property in CSS without causing re-paints on every frame, and heavily impacting the performance of your page? Short answer: you don’t. ![]()
