按钮设置边框

Bootstrap 5 也可以设置按钮多边框，鼠标移动到按钮上添加突出到效果：

<template>
    
  <div class="container mt-3">
    <h2>按钮设置边框</h2>
    <button type="button" class="btn m-1 btn-outline-secondary">次要按钮</button>
    <button type="button" class="btn m-1 btn-outline-success">成功</button>

    <button type="button" class="btn m-1 btn-outline-danger">危险</button>

    <button type="button" class="btn m-1 btn-outline-light text-dark">浅色</button>
  </div>  
</template>

不同大小的按钮

Bootstrap 5 可以设置按钮的大小，使用 .btn-lg 类设置大按钮，使用 .btn-sm 类设置小按钮：

<template>
  <div class="container mt-3">
    <h2>按钮设置边框</h2>
    <button type="button" class="btn m-1 btn-outline-secondary btn-lg">大按钮</button>
    <button type="button" class="btn m-1 btn-outline-success">普通按钮</button>
    <button type="button" class="btn m-1 btn-outline-primary btn-sm">小按钮</button>
  </div>  
</template>

块级按钮

通过添加 .btn-block 类可以设置块级按钮，.d-grid 类设置在父级元素中：
如果有多个块级按钮，你可以使用用 .gap-* 类来设置：

<template>
  <div class="container mt-3">
    <p>通过添加 .btn-block 类可以设置块级按钮，.d-grid 类设置在父级元素中：</p>
    <div class="d-grid gap-3">

      <button type="button" class="btn btn-primary btn-block">100% 宽度的按钮</button>
      <button type="button" class="btn btn-primary btn-block">100% 宽度的按钮</button>
    </div>
  </div>
</template>
