如何修复 col-lg-8 中的按钮元素?

How can I fixed element a button in col-lg-8?

我想要它,就像我在下面的图片中分享的那样,但我无法设置它。我正在分享我在下面写的代码。我该如何解决这个问题?

我的代码:

#mybtn{
    position: fixed;
    bottom: 10px;
    right: 10px;
}
<div class="row">
    <div class="col-lg-8" style="position: relative;">
        <p>this is my content</p>
        <button id="mybtn">My Fixed Button</button>
    </div>
    <div class="col-lg-4">
        <p>content area</p>
    </div>
</div>

您可以将 button 包裹在 div 中,然后在 div

上使用 d-flex justify-content-end

<div class="row">
  <div class="col-lg-8 bg-danger">
    <p>this is my content</p>
    <div class='w-100 d-flex justify-content-end'>
      <button id="mybtn" class='btn btn-primary btn-sm'>Button</button>
    </div>
  </div>
  <div class="col-lg-4">
    <p>content area</p>
  </div>
</div>
