在html中是否存在vr(垂直规则)? [英] Is there a vr (vertical rule) in html?
问题描述
我知道html中有一个hr(横向规则),但我不相信有一个vr(垂直规则)。我错了,如果没有,为什么没有垂直的规则?
不,没有垂直规则。 / p>
拥有一个并不合乎逻辑。 HTML是按顺序分析的,这意味着你从上到下布局你的HTML代码,从左到右你希望它从上到下,从左到右出现(通常)。
一个vr标签并不遵循这个范例。
然而,使用CSS很容易。例如:
< div style =border-left:1px solid#000; height:500px>< DIV>
请注意,您需要指定高度或填充容器的内容。
I know there is a hr (horizontal rule) in html, but I don't believe there is a vr (vertical rule). Am I wrong and if not, why isn't there a vertical rule?
No, there is no vertical rule.
It does not make logical sense to have one. HTML is parsed sequentially, meaning you lay out your HTML code from top to bottom, left to right how you want it to appear from top to bottom, left to right (generally)
A vr tag does not follow that paradigm.
This is easy to do using CSS, however. Ex:
<div style="border-left:1px solid #000;height:500px"></div>
Note that you need to specify a height or fill the container with content.
