With em , the child element inherits the value of its parent and up to the grandparent. This alters the supposed pixel value as the inherited value is put into consideration. To calculate the padding value of the. The section having page-wrapper class inherits the font size of the parent html element 16px. It multiplies that value by the font size 1. Apparently, the value of the padding specified on the container class will inherit from the parent element.
If the container class specifies a font size in em unit, the calculation will be extended further to use that value. To override this inherited value, you need to explicitly set the unit of the element being styled to px. Note that the font size value of the div with container class above is computed based on its parent element, not the root. The interesting thing here is that the Parent and Child in the HTML above do not have the same font size irrespective of the fact that they share the same class name.

On the other hand, if we use pixels, users needing bigger sizes will have to zoom at first but the page will still work correctly afterwards; if elements stop fitting on the screen, media queries will do their work. But the 16px default in the browser is far too small to read large amounts of text comfortably. Images, et al, all display well next to this font.
I have always preferred a slightly larger text that the default, even before 4K, due to the fact the I speed-read; overly small fonts make reading harder. When I zoom these sites the most common anomaly is that images are oversized. This is certainly true in Firefox, and Brave the browsers I use for daily browsing. So, yes, you are missing something.
