Animations should look smooth and also perform well.
Badly designed animations can make websites slow and feel laggy.
In this lesson, you will learn how to create animations that are both beautiful and fast.
Transform and opacity animations are the fastest and smoothest.
They do not cause heavy layout recalculations in the browser.
Opacity changes are also very efficient for animations.
They work smoothly even on low-end devices.
This is a real-world performance friendly animation.
