padding in em and px

Hosun  wrote Hi, Q1. (red arrows) I set each for em and px padding: 0.5em 1.5em; padding: 8px 24px; Where does the difference come from? I think the second button shoul be like the first one. Q2. (blue arrow) How to make a enough space between the paragraph and the button. Link EmRem-Church Hosun Kang

The second button will never be like the first one because you have explicitly set the padding in px and that never changes from device to device, it will always default to the specified px padding, unless you specifically change it using a media query.

I always use px because I personally find em and rem too freaking complex and I don't always want elements to be sized in 'ratio-aspect' to each other on smaller devices so I go in, look at the layout visually and then apply a size I think looks correct. But thats just me.

Its a little more work but I think the overall result looks more pleasing
