我是引导程序的初学者,我无法理解这个概念。
下面的代码是什么意思less
?
// Creates wrapper for a series of columns
.make-row(@gutter: @grid-gutter-width) {
// Then clear the floated columns
.clearfix();
@media (min-width: @screen-sm-min) {
margin-left: (@gutter / -2);
margin-right: (@gutter / -2);
}
// Negative margin nested rows out to align the content of columns
.row {
margin-left: (@gutter / -2);
margin-right: (@gutter / -2);
}
}
