CSS Animation Tutorial | CSS Speed Coding

Hey everyone! Welcome to yet another exciting tutorial. In today’s tutorial, we will be creating an animation in which a cat is watching the night sky. To create is amazing animation, we will need HTML and CSS. No images or javascript are needed at all. Also, the animation we will be creating will be a pretty basic one. So even beginners can try out this one.
 
If you would like to learn animations, I have a bunch of tutorials on my youtube channel. You can check them all in this playlist here. Also, don’t forget to subscribe to my youtube channel, where I post regular HTML, CSS and Javascript tutorials.
 

Video Tutorial:

In case you prefer to code along with me, you can check out the video tutorial here down below.

HTML:

Let us first create the project folder structure required for this tutorial. We start by creating a folder called – Cat Animation. Within this folder, we have two files. The first is index.html and, the second is style.css. They are the HTML file and the stylesheet respectively.

We begin with the HTML code. First, copy the code provided below and paste it into your HTML file.

We first need to create a basic layout of divs that will be further styled and animated. The HTML consists of the main div with a class name container. Within the container, we have a div with a class name window. The window div comprises mountain-1, mountain-2, kitty, moon and star.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Cat Animation</title>
    <!-- Stylesheet -->
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <div class="container">
      <div class="window">
        <div class="mountain-1"></div>
        <div class="mountain-2"></div>
        <div class="kitty">
          <div class="ear"></div>
        </div>
        <div class="moon"></div>
        <div class="star"></div>
      </div>
    </div>
  </body>
</html>

CSS:

Now to style these divs into required shapes, we use CSS. Firstly copy the code below and paste it into your stylesheet. If you don’t know how to create various shapes using CSS, check out this tutorial here.

After shaping and positioning the divs, our CSS art is ready. Now to add animation to this art we use animations and keyframes. We name the animation as tail and set the animation duration to 4 seconds. We also set the transform-origin to the top.

At 50% of keyframes, the tail rotates by 10deg. This creates the effect of a wagging tail. To add the final touch we add twinkle animation to the stars. At 50% of keyframes duration, we reduce the opacity of the star by 40%.
