TUTORIAL how to create a preloader with CSS.


How To Create a Loader


Step 1) Add HTML:

Example

<div class="loader"></div>
Step 2) Add CSS:

Example

.loader {
    border: 16px solid #ff4000; /* */
    border-top: 18px solid #ff4000; /* Blue */
    border-radius: 50%;
    width: 120px;
    height: 120px;
    animation: spin 2s linear infinite;
}

@keyframes spin {
    0% { transform: rotate(0deg); }
    100% { transform: rotate(360deg); }
}

Example Explained

The border property specifies the border size and the border color of the loader. The border-radius property transforms the loader into a circle.

The blue thing that spins around inside the border is specified with the border-top property. You can also include border-bottom, border-left and/or border-right if you want more "spinners" .

The size of the loader is specified with the width and height properties.

At last, we add an animation that makes the blue thing spin forever with a 2 second animation speed.

Note: You should also include -webkit- and -ms- prefixes for browsers that do not support animation and transform properties. Click on the example to see how.
