极客教程Bootstrap 5按钮概要
Bootstrap 5提供了一系列的类，可以用来在我们的项目中创建轮廓按钮，即没有背景颜色的按钮。轮廓按钮类删除了应用于按钮的任何背景颜色或背景图片样式。我们将使用.btn-outline-*类来创建轮廓按钮，其中*被替换为颜色名称。
按钮大纲类：
- .btn-outline-primary
- .btn-outline-secondary
- .btn-outline-success
- .btn-outline-danger
- .btn-outline-warning
- .btn-outline-info
- .btn-outline-light
- .btn-outline-dark
语法:
<button type="button" class="btn btn-outline-*">
*
</button>
例子1：在这个例子中，我们将使用按钮轮廓类来创建轮廓按钮。
