使用css写带纹理渐变背景图的示例代码

html,body{
  background: #000;
  min-width: 1024px; 
  background-image: linear-gradient(to right, #000 -6%, #703ccc, #000 110%);
}

.Diffuse{
    min-width: 1024px;
    height: auto;
    position: relative;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    background-color: transparent;
    background-image: url("data:image/svg+xml,%3Csvg width='6' height='6' viewBox='0 0 6 6' xmlns='http://www.w3.org/2000/svg'%3E%3Cg fill='%23000000' fill-opacity='0.61' fill-rule='evenodd'%3E%3Cpath d='M5 0h1L0 6V5zM6 5v1H5z'/%3E%3C/g%3E%3C/svg%3E");
    }
