baseUnit
DOM module to replicate the vmin/vmax CSS unit. Take a look at an example.
Example
I commonly use this to set the base font-size on HTML in conjunction with rem units in my CSS. Here's an example of the JS:
`
var baseUnit = require('baseunit')
var head = document.getElementsByTagName('html')[0]
function setUnit () { var size = baseUnit() head.style.fontSize = size + '%' }
setUnit() window.addEventListener('resize', setUnit, false)
