How to display a blank div element?
提问by Xofo
I have a blank div class that is called spacer ... it has a blue background and a width of 100% of the container (the body) ...
我有一个空白的 div 类，称为间隔...它有一个蓝色背景和容器（主体）的 100% 的宽度...
What I have found is that the spacer will not DISPLAY unless I toss some character in it. I can color the character blue so it is hidden, but that is so inelegant.
我发现除非我在其中折腾一些字符，否则垫片不会显示。我可以将角色涂成蓝色以便隐藏，但这太不优雅了。
What is the CORRECT way to do this.

Give it a height.
给它一个高度。
Otherwise, with no content, it has zero height and is effectively invisible.
否则，如果没有内容，它的高度为零并且实际上是不可见的。
