getComputedStyle

One task I needed to deal with the past week is to find a way to set a child’s height based on the parent’s CSS min-height.

Problem is that there is no DOM property to get this minHeight.

A quick search and I came across a DOM API called getComputedStyle and it returns the computed style of the component based on the different classes and styles and CSS properties including the minHeight that I needed.

1getComputedStyle(element);
2getComputedStyle(element, pseudoElt);
