javascript - 增加引导复选框的大小

问题描述

我正在使用官方引导文档中的代码创建一个简单的复选框：

<div class="custom-control custom-checkbox">
    <input type="checkbox" class="custom-control-input" id="customCheck" name="example1">
    <label class="custom-control-label" for="customCheck">Check this custom checkbox</label>
</div>

我想知道如何使复选框比现在大？我尝试编辑 csscustomCheck并更改 height 和 width 属性，但这不会增加框的大小。

解决方案

我添加了诸如引导开关之类*-sm, *-md, *-lg, *-xl的类。

在这里，我使用一个 @mixin切换了所有分辨率（@mixin 与 JS 函数非常相似，但它不返回任何内容）。
