If you want to learn more on that topic, Scott E. User can concentrate on the task (of finding an element). In this example, the animation shows how the menu opens and how the elements appear. The brain doesn’t have to interpolate the stares, so the interface feels less disruptive. This helps decreases the cognitive load for the brain. So, animation explicitly show users the in-betweens. And this drains resources from the brain, aka cognitive load. Then we flipped the notebook, creating a moving character animation? When change happened without transition, the brain tries to detail all the steps to understand the “what just happened between those two states?” The brain does the flipbook drawing. You know, when we were drawing stick humans in different positions in the right corner of a note book. And it’s a cognitive effort for our users. When abrupt change happen, the brain is trying to figure what happened between the states.
So, animations decrease cognitive load, by making state changes more natural.Ĭhange of states without animation is disruptive to human mental models and are hard to process. Today, the power of CSS brings a lot of animation options and possibilities directly in the browser. Operating systems, videos games, and more recently apps and websites also started using animations in the last years to build better product and make the user experience better.
But animations are not limited to cartoons. Those are Disney’s 12 animation principles illustrated. Most of the time when we say “animation”, people think about cartoons. So big warning: this talk and those slides contain a LOT of animations. ** Last Update: Novem** UX ❤ Animations – How and where animations can help users So you will also find here a transcript with CSS codepen and video examples and LOT of resources to dig further in specific topics and the replay of the talk at the end of the article.

I published the PDF version of the slides, but a PDF of a talk on animations is boring. And what you need to be careful about to build inclusive and accessible motion and avoid making some people sick. I explain how our brain works, why and how animations contribute to improving user experience.

With practical examples, I show why certain animations work better than others and how to find the best timing and duration to build UI animations that “feel right”. In the talk, I give a quick reminder of CSS syntax to build transitions and animations. But how do we make sure that our CSS animations and transitions will be meaningful to our users? That they will not be just some annoying “in-your-face” eye candy? How can CSS animations enhance your user experience? With CSS and JS progress, implementing animations on websites has never been easier. Remember that the following content might be outdated. contain: Resizes the image to the maximum size that can fit into the viewport without cropping.īackground-size: is often combined with background-position: center, which centers the image in the viewport and with background-repeat: no-repeat, which ensures a once-only display.This content is 2 years old.cover: Resizes the image to cover the viewport, sometimes necessitating stretching or cropping.percentage: Sets the image width and height as a percentage of the parent element.To create a full-page background, add the background-size: property to your main or body styling and then specify how you want the background to be filled. These backgrounds are especially ideal for high-resolution images that you want to display in a large-enough size without having the audience open them separately. Full-page backgrounds are a great choice for embellishing webpages, but be sure to pick images that are not overwhelming.
