尝试这个:
background-image: -webkit-repeating-linear-gradient(-45deg, rgba(0, 0, 0, .1), rgba(0, 0, 0, .1) 25%, transparent 25%, transparent 50%, rgba(0, 0, 0, .1) 50%);
background-image: -moz-repeating-linear-gradient(-45deg, rgba(0, 0, 0, .1), rgba(0, 0, 0, .1) 25%, transparent 25%, transparent 50%, rgba(0, 0, 0, .1) 50%);
background-image: -ms-repeating-linear-gradient(-45deg, rgba(0, 0, 0, .1), rgba(0, 0, 0, .1) 25%, transparent 25%, transparent 50%, rgba(0, 0, 0, .1) 50%);
background-image: -o-repeating-linear-gradient(-45deg, rgba(0, 0, 0, .1), rgba(0, 0, 0, .1) 25%, transparent 25%, transparent 50%, rgba(0, 0, 0, .1) 50%);
background-image: repeating-linear-gradient(-45deg, rgba(0, 0, 0, .1), rgba(0, 0, 0, .1) 25%, transparent 25%, transparent 50%, rgba(0, 0, 0, .1) 50%);
-webkit-background-size: 4px 4px;
-moz-background-size: 4px 4px;
-o-background-size: 4px 4px;
background-size: 4px 4px;
/* Background size must be an even number! */
