Фон неровный

Я ищу эффект фона, как это (в чистом CSS), как я могу это сделать?

html,
body {
  height:100%;
  background-color:#3D3D3D;
  display:flex;
}

div {
  height: 100px;
  width:100px;
  margin:10px auto;
  background-image: linear-gradient(45deg, #868686 25%, transparent 25%, transparent 75%, #868686 75%, #868686), linear-gradient(45deg, #868686 25%, transparent 25%, transparent 75%, #868686 75%, #868686);
  background-position: 0 0, 51px 51px;
  background-color: #222222;
  background-size: 2px 2px;
}

Решение

Вот чистое решение CSS создать 4 linear-gradients как это с repeat-x и соответствующее позиционирование.

body {
  margin: 0;
  height: 100vh;
  background:
    linear-gradient(to right, #868686 50%, #3d3d3d 50%) 0 0 / 50px 25px repeat-x,
    linear-gradient(to right, #3d3d3d 50%, #222    50%) 0 0 / 50px 50px repeat-x,
    linear-gradient(to right, #3d3d3d 50%, #868686 50%) 0 0 / 50px 75px repeat-x,
    linear-gradient(to right,    #222 50%, #3d3d3d 50%) 0 0 / 50px 100px repeat-x;
}

Затем повторите linear-gradient много много раз. Демо-версия:

body {
  margin: 0;
  height: 100vh;
  background:
    linear-gradient(to right, #868686 50%, #3d3d3d 50%) 0 0 / 50px 25px repeat-x,
    linear-gradient(to right, #3d3d3d 50%, #222    50%) 0 0 / 50px 50px repeat-x,
    linear-gradient(to right, #3d3d3d 50%, #868686 50%) 0 0 / 50px 75px repeat-x,

Конечно, вы можете использовать любой язык программирования или какой-либо CSS-препроцессор для генерации CSS-свойств этого монстра.

Но если честно, я бы использовал SVG для этой вещи с 8 квадратами. Демо-версия:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 20 40">
  <rect x="0" y="0" width="10" height="10" fill="#868686"/>
  <rect x="10" y="0" width="10" height="10" fill="#3d3d3d"/>
  <rect x="0" y="10" width="10" height="10" fill="#3d3d3d"/>
  <rect x="10" y="10" width="10" height="10" fill="#222"/>
  <rect x="0" y="20" width="10" height="10" fill="#3d3d3d"/>
  <rect x="10" y="20" width="10" height="10" fill="#868686"/>
  <rect x="0" y="30" width="10" height="10" fill="#222"/>
  <rect x="10" y="30" width="10" height="10" fill="#3d3d3d"/>
</svg>

Демонстрация с SVG (работает только в Chrome, вам нужно использовать внешний SVG (предпочтительный способ) или избежать разметки SVG):

body {
  background: url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 20 40"><rect x="0" y="0" width="10" height="10" fill="#868686"/><rect x="10" y="0" width="10" height="10" fill="#3d3d3d"/><rect x="0" y="10" width="10" height="10" fill="#3d3d3d"/><rect x="10" y="10" width="10" height="10" fill="#222"/><rect x="0" y="20" width="10" height="10" fill="#3d3d3d"/><rect x="10" y="20" width="10" height="10" fill="#868686"/><rect x="0" y="30" width="10" height="10" fill="#222"/><rect x="10" y="30" width="10" height="10" fill="#3d3d3d"/></svg>') 0 0 / 40px 80px repeat;
}

Демо с экранированным встроенным SVG, работает везде, но менее ремонтопригодно:

body {
  background: url('data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A//www.w3.org/2000/svg%22%20viewBox%3D%220%200%2020%2040%22%3E%3Crect%20x%3D%220%22%20y%3D%220%22%20width%3D%2210%22%20height%3D%2210%22%20fill%3D%22%23868686%22/%3E%3Crect%20x%3D%2210%22%20y%3D%220%22%20width%3D%2210%22%20height%3D%2210%22%20fill%3D%22%233d3d3d%22/%3E%3Crect%20x%3D%220%22%20y%3D%2210%22%20width%3D%2210%22%20height%3D%2210%22%20fill%3D%22%233d3d3d%22/%3E%3Crect%20x%3D%2210%22%20y%3D%2210%22%20width%3D%2210%22%20height%3D%2210%22%20fill%3D%22%23222%22/%3E%3Crect%20x%3D%220%22%20y%3D%2220%22%20width%3D%2210%22%20height%3D%2210%22%20fill%3D%22%233d3d3d%22/%3E%3Crect%20x%3D%2210%22%20y%3D%2220%22%20width%3D%2210%22%20height%3D%2210%22%20fill%3D%22%23868686%22/%3E%3Crect%20x%3D%220%22%20y%3D%2230%22%20width%3D%2210%22%20height%3D%2210%22%20fill%3D%22%23222%22/%3E%3Crect%20x%3D%2210%22%20y%3D%2230%22%20width%3D%2210%22%20height%3D%2210%22%20fill%3D%22%233d3d3d%22/%3E%3C/svg%3E') 0 0 / 40px 80px repeat;

Вариант 1: проще, гибче и эффективнее было бы использовать base64, который вы можете легко создать с http://www.patternify.com/ (или что-то подобное). Будет создан base64, который вы можете реализовать как background-image URL с repeat,

Вариант 2: только CSS решение от CSS3 Pie. Приспособьте свои цвета по мере необходимости.

Не совсем требуемый фон, но я думаю, что он прост и удобен в использовании.

div{
