My current issue involves trying to obtain the font size of an element in the following manner:
getComputedStyle(MyTargetElement , "").getPropertyValue('font-size')The result is coming back as 16px, when it should actually be 14px. Why is this discrepancy occurring?
<RootElement /> fontsze:14px
<GranParent /> fontsze:1rem
<Parent /> fontsze:1em
<MyTargetElement /> fontsze:1em
Where did I go wrong in this scenario?
The main element of a ReactJS application is not the actual root HTML element (<html>), which serves as the foundation for rem calculations. Instead, you need to mount your application within another element, often not even a direct descendant of the <body> element.
If you haven't specified a font-size for the <html> element, the browser will default to its own stylesheet, resulting in a computed value of 16px for the 1rem-1em-1em chain.
