Question

我正在尝试在产品页面的下拉框下方移动一个按钮。这样一来，每行便会显示一个信息。我尝试在按钮周围放置一个div标签，以查看该标签是否被视为位于上一个元素下方的单独元素，但是该标签不起作用，所以我迷失了将购买按钮置于尺寸和1以下的操作盒子。

Answer 1

这里有很多错误。

<br>标签不应用于元素定位。这应该严格保留用于文本。
如果您不希望元素显示行，则不建议初学者将其display属性设置为inline-block可能是个好主意。
甚至还有一些语法错误（例如，过多的</div>标签，而没有）。通常，我建议您以某种形式的linter编写代码，因为它存在一些可读性问题。

我做了最起码的删除多余的<br>标记的操作，并将clear:both添加到.Buy类格式中。产生期望的结果。
