Let's start

So, start with basic HTML structure. And after that, create a <div> with class loading-box it will contain our loader. And inside that, create another <div> with class loader.

<div class="loading-box">    <div class="loader"></div></div>

And for styling first, give basic style.

*{    margin: 0;    padding: 0;    box-sizing: border-box;}body{    width: 100%;    height: 100vh;    display: flex;    justify-content: center;    align-items: center;    background: #fefefe;}.loading-box{    position: relative;    width: 400px;    height: 50px;    border-radius: 50px;    border: 2px solid #ededed;    overflow: hidden;}

In above CSS, we are using flex box to center our loading box.

Output

Now, style loader.

.loader{    width: 100%;    height: 100%;    position: absolute;    border-radius: 50px;    background: linear-gradient(45deg, #b6b5ff, #ff9797);    left: 0%;}

Output

You can see we are done with the loader, Now let's animate this. As you can notice, we have left property set to 0% change it to -100% and give animation.

.loader{    left: -100%;    animation: load 3s linear infinite;}@keyframes load{    0%{        left: -100%;    }    100%{        left: 100%;    }}

Output

So, it's done. I hope you understood each and everything. If you have doubt or I missed some point let me know in the comments.
