Technologies for creating web animations
So, you already know the most amazing and popular website animation styles and types. Now, it’s time to learn how you can add them to a website. Once designers have created or chosen the animation, they forward it to front-end developers – programming magicians who should put it on a site. Here we will consider the best technologies and frameworks used for web animation.
CSS
The first thing worth mentioning is the CSS animation. It helps front-end developers make transitions between different states using keyframes. This type of animation is lightweight, high-performing, and doesn’t require any external libraries for implementation.
Developers can add animation to a web page by using DOM (Document Object Model) and setting customized properties. Another advantage of CSS animations is excellent compatibility with different screen sizes, which is the number one factor that makes a great website. The only disadvantage is that you can imitate realistic motion using this animation type.
JavaScript
This powerful programming language is also beneficial when it comes to website animation. It gives much more flexibility compared to CSS animations.
JavaScript’s only con is that it implements all animation through external libraries, impacting animation performance and loading time. It is mostly applied when you need to pause, slow down, or stop the animation.
SVG
Do you know what the abbreviation SVG means? It’s Scalable Vector Graphics. You can understand even from the name that SVG is a perfect solution for creating easily scalable animation. It looks excellent on a website, even if you zoom on it since SVG doesn’t have pixel restrictions.
Developers can use CSS to make SVG elements. Also, it has its own animation functionality that allows creating more complicated animations.
Canvas
Canvas is great for implementing complicated animations and rendering large-scale visuals. It’s a pixel-based solution empowering you to make complicated images with different shades, colors, and motion. And what’s most important – it doesn’t affect the animation performance.
WebGL
WebGL is usually used to generate sophisticated animation effects and 3D rendering. The most impressive fact about WebGL is that it can render animation at 60 frames/second (just imagine!). For WebGL, developers should also use Canvas, but it’s quite a complicated process.
