语法:
@for <variable> from <expression> to <expression> { ... }
或
@for <variable> from <expression> through <expression> { ... }
如果使用 to,则排除最终数字;如果使用 THROUGH,则包含它。
SCSS
$base-color: #036;
@for $i from 1 through 3 {
ul:nth-child(3n + #{$i}) {
background-color: lighten($base-color, $i * 5%);
}
}
编译为 CSS 结果:
CSS
ul:nth-child(3n + 1) {
background-color: #004080;
}
ul:nth-child(3n + 2) {
background-color: #004d99;
}
ul:nth-child(3n + 3) {
background-color: #0059b3;
}
