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

HTML5 custom elements (or pure CSS)

1. javascript

Register your element.

var vr = document.registerElement('v-r'); // vertical rule please, yes!

*The - is mandatory in all custom elements.

2. css

v-r {
    height: 100%;
    width: 1px;
    border-left: 1px solid gray;
    /*display: inline-block;*/    
    /*margin: 0 auto;*/
}

*You might need to fiddle a bit with display:inline-block|inline because inline won't expand to containing element's height. Use the margin to center the line within a container.

3. instantiate

js: document.body.appendChild(new vr());
or
HTML: 

*Unfortunately you can't create custom self-closing tags.

Don't want to mess with javascript?

Simply apply this CSS class to your designated element.

css

.vr {
    height: 100%;
    width: 1px;
    border-left: 1px solid gray;
    /*display: inline-block;*/    
    /*margin: 0 auto;*/
}

*See notes above.
