问题描述
您好我正在尝试学习SASS / SCSS并试图重构我自己的mixin for clearfix
Hi I'm trying to learn SASS/SCSS and am trying to refactor my own mixin for clearfix
我想要的是mixin基于什么我是否通过了一个宽度的混合。
what I'd like is for the mixin to be based on whether I pass the mixin a width.
到目前为止的想法(伪代码,因为我将包括其他mixins)
thoughts so far (pseudo code only as I will be including other mixins)
@mixin clearfix($width) {
@if !$width {
// if width is not passed, or empty do this
} @else {
display: inline-block;
width: $width;
}
}
这是我以为我可以称之为它的方式,但它是不工作。
here's how I thought I might call it, but it's not working.
@include clearfix();
或
@include clearfix(100%)
或
@include clearfix(960px)
我很感谢你在最佳或正确的方式上提供任何帮助!
I'd appreciate any help on the best or right way to do this!
推荐答案
你可以试试这个:
$width:auto;
@mixin clearfix($width) {
@if $width == 'auto' {
// if width is not passed, or empty do this
} @else {
display: inline-block;
width: $width;
}
}
我不确定你的预期结果,但是设置默认值应该返回false。
I'm not sure of your intended result, but setting a default value should return false.
