Website Animations - GSAP Guide

[mostakimvip06]

There are many ways to add spectacular animations to our website. In this post, we will focus on one approach that will allow us to quickly achieve really interesting visual effects. We will take a look at the GSAP library - GreenSock , and then discuss the basic concepts and approaches that will allow us to make eye-pleasing animation. The version of the library discussed in this article is version 3.

Summary
What is GSAP?
It's a library that provides us with methods to easily add and manage animations on our website . Most of the functionality is provided for free, but for some really cool stuff, like advanced SVG animations, you need to have a license. However, we'll focus on the free parts of this library.

Animating DOM elements
The first method we will learn about is gsap.to() . It takes three arguments, the first of which is the animated element. We can provide it as a selector or a DOM element. The second argument takes an object with the configuration russia telemarketing data of our animation. The third argument is responsible for the position of the animation call relative to the timeline.


When configuring our animation we can use options such as:

x - change of object in x axis,
y - change of object in y-axis,
z - change of object in z axis,
rotation - changing an object by rotating it,
transformOrigin - change the pivot point,
scale - change the size of the object,
skew - changing the size of an object,
perspective - change of perspective,
opacity - changing the transparency of an object,
delay - animation delay,
duration - determines the time in which our animation will be performed,
Ease - determines the pace of animation execution.
Detailed descriptions and other features can be found at this address .

Timeline
If we want to compose several animations one after another, it is worth using the gsap.timeline() method. Thanks to it, we can sequence the execution of our animations. Without this method, in order to achieve a similar effect, we had to use the delay property . The approach using the timeline significantly simplifies our code. On the other hand, the optimization of our code contributes to its easier maintenance.

The gsap.timeline() method takes as its first argument a configuration object in which we can set the time after which the next animations will be executed or set the animation to loop.


The third argument is responsible for at what point in our animation sequence the animation should be executed. Passing the value “-=1” will execute it 1 second before the previous one finishes, while passing the value “+=1” will execute the animation 1 second after the previous one finishes.

Animation pace

All these values ​​and how the elements behave after they are applied can be checked at this address . We can also use the tool at the link above to create our own animation tempo.
