Introduction

In this article, we will see how to create a loading screen.
Step 1
 The first step is to create an Index.html file and put the following code in it.
Index
In the preceding HTML file, we have added three divs. In the last div we have added five divs. In these five divs we are loading text as content that will be displayed as an output.
But currently, if we view this Index.html in a browser, it will look like this.

Step 2
The next step is to add some styles and for that create a CSS file “container” and specify the CSS file address in the HTML file.

In the container.css file write the following:
container
Refresh the page.
Refresh the page
Our elements shifts 200px vertically and horizontally.
Set the padding-left to 70px.
Set the padding
Refresh the page.
page
Our container is now shifted 70px from the left.
Step 3
The next step is to add some CSS rules for the inner-container.

It will shift the elements more to the right and downward.

Step 4
The next step is to add some styles for our load div.
  1. /*.load > div means we want to select only the div that sits directly after the loaded container. This will not take any child element present in the inner div.
  2. */
  3. .load > div{
  4. /*give a font-size of 20px*/
  5. font-size: 20px;
  7. /*add a line-height of 90px. It will shift the element downwards.*/
  8. line-height: 90px;
  10. /*It will shift the element to the center*/
  11. text-align: center;
  13. /*set the background color to white*/
  14. background-color: white;
  16. /*set the float property to left which will float elements from left to right*/
  17. float: left;
  19. /*set the margin-left property to 150px, it will shift the elements 150px from the left*/
  20. margin-left: 150px;
  22. /*set the width to 20px for each elements*/
  23. width: 20px;
  25. /*set the opacity to 1 which is nothing but the visibility level*/
  26. opacity: 1.0;
  28. /*Set the transform scale to 0.8 that will reduce the scale of the elements*/
  29. -webkit-transform: scale(0.8);
  31. /*this "load" is a keyframe that we want to bind to a selector*/
  32. -webkit-animation-name: load;
  34. /*animation duration*/
  35. -webkit-animation-duration: 1.20s;
  37. /*set the iteration to infinite if you want the animation non-stop*/
  38. -webkit-animation-iteration-count: infinite;
  39. }
Refresh the page. The elements scale will reduce to 0.8. But no animation will happen.

Step 5
The next step is to add a keyframe with a named load and we will bind this keyframe to the .load selector.
keyframe
Since we have already bound this keyframe to the selector.
  1. /*this load is a keyframe that we want to bind to a selector*/
  2. -webkit-animation-name: load;
Refresh the page and you will see all the five loading contents. Now the animation is from a scale of 1.2 to 0.7 with an opacity of 1 to 0.1.
loading contents
But all the contents animate at the same time. Now let's say we want each of the contents to animate one by one in a linear way and for that, we need to set an animation-delay for all the elements.
Step 6
animation
Refresh the page and you will see the elements animate one after another.
So, we have learned how to create a simple loading screen using CSS but there are many more things you can do with this. So keep exploring.
