interpolate values in a css string
npm install lerp-css-string
Interpolates the values between two CSS strings, returning a new string.
``js
var lerp = require('lerp-css-string')
lerp('10px', '0px', 0.5) // -> '5px'
lerp('100%', '50%', 0.5) // -> '75%'
lerp('100px 25%', '50px 20%', 0.5) // -> '75px 22.5%'
lerp('360, 50%, 25%', '200, 100%, 50%', 0.5) // -> '280 75% 37.5%'
`
#### lerp(str1, str2, alpha)
Lerps between str1 and str2 based on the given alpha (typically 0.0 to 1.0), returning a new string with interpolated values and their units. Numbers and units are expected to be tightly packed (e.g. 50px`).
