我想用LESS生成这个CSS代码:
.navbar-default .navbar-nav > .active > a,
.navbar-default .navbar-nav > .active > a:focus,
.navbar-default .navbar-nav > .active > a:hover {
background-color: blue !important;
}
但目前我用LESS生成这个CSS代码:
.navbar-default .navbar-nav > .active > a {
background-color: blue !important;
}
.navbar-default .navbar-nav > .active > a:focus {
background-color: blue !important;
}
.navbar-default .navbar-nav > .active > a:hover {
background-color: blue !important;
}
这是我的LESS代码:
.navbar-default {
//& always refers to the current selector.
.navbar-nav {
& >.active {
& > a {
background-color: blue !important;
&:focus {
background-color: blue !important;
}
&:hover {
background-color: blue !important;
}
}
}
}
}
答案 0 :(得分:2)
应该是:
.navbar-default {
.navbar-nav {
& >.active {
& > a {
&, &:focus, &:hover {
background-color: blue !important;
}
}
}
}
}
您可以将其简化为:
.navbar-default .navbar-nav >.active > a {
&, &:focus, &:hover {
background-color: blue !important;
}
}
两者都将输出以下内容:
.navbar-default .navbar-nav > .active > a,
.navbar-default .navbar-nav > .active > a:focus,
.navbar-default .navbar-nav > .active > a:hover {
background-color: blue !important;
}
