Code interpretation

To define the DOM, there are only 1 elements:

<p class= "Loader" ></p>

Center display:

body {    margin:0;    HEIGHT:100VH;    Display:flex;    Align-items:center;    Justify-content:center;    Background:radial-gradient (Darkgreen 30%, forestgreen);}

Define Container Dimensions:

. loader {    width:10em;    Height:10em;    font-size:20px;}

2 groups of dots are drawn with Box-shadow:

. loader::before,.loader::after {    content: ';    Position:absolute;    Width:1em;    Height:1em;    Background-color:currentcolor;    Box-shadow:        0 0, 2em 0, 4em 0, 6em 0,        0 2em, 2em 2em, 4em 2em, 6em 2em,        0 4em, 2em 4em, 4em 4em, 6em        4em, 0 6em, 2em 6em, 4em 6em, 6em 6em;    border-radius:50%;}. Loader::before {    color:gold;}. loader::after {    color:dodgerblue;}

Defining animations:

@keyframes Round {    0% {        transform:translatex (0) translatey (0);    }    25% {        Transform:translatex (3em) translatey (0);    }    50% {        Transform:translatex (3em) Translatey (3em);    }    75% {        Transform:translatex (0) Translatey (3em);    }}

Finally, apply the animation effect to the dot matrix:

. loader::before,.loader::after {    animation:round 2s ease infinite;}. Loader::after {    animation-delay: -1s;}

Done!
