Drawing a grid using CSS

Answer 1

body { box-sizing:border-box; margin:0; height:100%; width:100%; background-size:100px 100px;
       background-image: repeating-linear-gradient(0deg, transparent, transparent 99px, #ccc 99px, #ccc 100px), 
       repeating-linear-gradient(-90deg, transparent, transparent 99px, #ccc 99px, #ccc 100px); 
     }
