javascript - 如何将购买按钮移到下拉框下方？

标签 javascript html css

我想在我的产品页面的下拉框下方移动一个按钮。以便每行显示一个信息。我尝试在按钮周围放置一个 div 标签，看看它是否被视为位于前一个元素下方的单独元素，但这不起作用，所以我不知道该怎么做才能使购买按钮位于 size 和 1 下方盒子。

最佳答案

这里有很多错误。

  1. <br>标签不应该用于元素定位。这应该严格保留用于文本。
  2. 如果您不希望您的元素显示一行，最好不要设置它们的 display。 inline-block 的属性(property)对于初学者。
  3. 甚至还有一些语法错误(例如过多的</div> 标签等等)。一般来说，我建议您使用某种 linter 编写代码，因为它存在一些可读性问题。

我做了最低限度的删除不必要的 <br>标记并添加 clear:both到 .Buy类格式化。产生期望的结果。
