Grainy texture using CSS gradients

Create a random-style background (grainy texture) using a few lines of code.

grainy background texture

html {
--s: 6px; /* control the size */

--g: repeating-conic-gradient(#774F38 0 25%,#ECE5CE 0 50%) 0/;
var(--g) calc(1*var(--s)) calc(7*var(--s)),
var(--g) calc(2*var(--s)) calc(5*var(--s)),
var(--g) calc(3*var(--s)) calc(3*var(--s)),
var(--g) calc(5*var(--s)) calc(2*var(--s)),
var(--g) calc(7*var(--s)) calc(1*var(--s));
