Get CSS property value with JS

Get CSS property value with JS

Just a little reminder to myself about reading the value of a CSS property (variable) using javascript:

getComputedStyle(element).getPropertyValue('--myprop')

Of course, if the value is numeric, it’s going to have its unit attached, such as ‘10px’

Just strip it to have the pure number:

getComputedStyle(element).getPropertyValue('--myprop').replace('px', '')
