SVGs, or Scalable Vector Graphics, are an image type that’s entirely composed of coding language. A remarkable part of working with SVGs is their responsive properties more natural and manageable. They can also be animated & interactive.
CSS is often used for animating SVG elements. Here’s a brief guide on how to do that:
Step 1. Create an SVG Image
Firstly, you need to create or have your SVG image. You can use an online SVG editor like vectr.com or design software like Adobe Illustrator for creating SVG images. A basic SVG may look something like below:
```
```
This will generate a circle.
Step 2. Applying CSS
The SVG object can be animated by applying CSS. Below is an example of a circle that changes its radius on mouse hover using CSS.
```
```
Step 3. More Complex CSS Animation with keyframes
For more complex animation, we can use CSS keyframes. The following is an example animation that makes the circle pulsate:
```
```
In this example, the circle’s radius shrinks to `20` and expands to `40` in a loop, creating a pulsating effect.
Remember that each SVG element has unique properties! For example, a rectangle has `width` and `height`, whereas a circle has `r` (radius). Be sure to animate the correct property for each SVG element.
Web browsers widely support SVG and CSS animations. However, for complex animations or animations trying to run at a smooth 60 FPS, JavaScript libraries like GSAP or Snap.svg are good options.
