Modern browsers can animate four things really cheaply: position, scale, rotation and opacity. The SolutionĪs I briefly mentioned before, when it comes to animating cheaply in modern browsers today, we really only have four options. All of our tests will be run at 6x slower, even our final performant code, to compare evenly. This is pretty unacceptable, even with the GPU performing at six times slower. When our tree first loads with the “bad” animation, we are getting a horrifying 10 FPS:Īt some points though, like in our bottlenecks above, we are getting 0 - 1 FPS. In terms of frames per second, users like to have at least 60 FPS. Yes, that is just milliseconds, however, if we take longer than 16 ms to render a frame, the people will notice. This particular bottleneck is taking 94.85 ms. I slowed the CPU down six-fold to attempt to simulate a chugging MacBook (I would have put it lower if I could have). As the great Lewis and Irish say in their article, “High performance animations”: Modern browsers can animate four things really cheaply: position, scale, rotation and opacity. With CSS in modern browsers, you really only have four options when it comes to animating with no problems. If we check out the performance panel in our devtools for Chrome, we see bottlenecks in our load time! You're probably asking (in your best enraged angry developer voice), “What could cause this?!” Well, turns out our animations are no bueno. It simply takes some awareness rather than a haphazard slapping around of animations. Do we even have other options? Can we even animate without crashing browsers in this world of 2018? I wanted to go over the different options we have. The animation, a Christmas tree and snow drawing, are obviously not performant-so much so that we can’t even use them. Not that my newest MacBook fared much better, the fans sounded like we were prepping to go into outer space when the animation ran for more than a few minutes. However, we had to comment out the animation and Christmas tree because it was causing our older MacBook laptop to crash. I found this lovely animation online and cleaned it up a bit for a Secret Santa app me and my husband worked on for the holidays. Dependencies: none.Learn how to improve animation performance in CSS with a holiday-themed example from Alyssa. These are used to create more complex visual effects, such as turbulence and displacement in the pond’s water. The code includes SVG elements with filters. For example, the blur filter is used to create a blur effect on the pond’s surface, and the drop-shadow filter is used to create a shadow effect for the quote. The code also makes use of CSS filters to create interesting visual effects. The rule is used to specify the behavior of these animations. The animation property is used extensively throughout the code to create dynamic effects, such as the movement of the fish and the ripples in the pond. The CSS part of the code is used to style these HTML elements. These div elements are nested and classed to represent different components of the scene, such as a pond, fish, ripples, and a quote. The HTML part of the code primarily consists of div elements, which are used to create a visual scene. The provided code snippet is a fascinating example of how HTML and CSS can be used to create dynamic and visually appealing web content.
