用萨斯骑行浏览颜色列表

如果纯CSS有可能，Sass也有可能。这将适用于多种颜色：

$colors: red, orange, yellow, green, blue, purple;

@for $i from 1 through length($colors) {
    li:nth-child(#{length($colors)}n+#{$i}) {
        background: nth($colors, $i)
    }
}

输出：

li:nth-child(6n+1) {
  background: red;
}

li:nth-child(6n+2) {
  background: orange;
}

li:nth-child(6n+3) {
  background: yellow;
}

li:nth-child(6n+4) {
  background: green;
}

li:nth-child(6n+5) {
  background: blue;
}

li:nth-child(6n+6) {
  background: purple;
}
