Is there a vr (vertical rule) in html?

Question

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?

Answer 1

Today is possible with CSS3

hr {
  background-color:black;
  color:black;
  -webkit-transform:rotate(90deg);
  position:absolute;
  width:100px;
  height:2px;
  left:100px;
}
