When to use EM of REM?


I am new here and come from a completely different work sector, so perhaps my questions are a bit easy to answer. ;) I am now working on CSS with great enthusiasm, but I still have a few questions about EM/REM:

  • I can't find a clear answer to when you're using EM or REM?

  • When do you add the above in the writing process? Right at the start or doesn't it matter?

Thanks in advance!

If you can check the MDN Web docs,under the heading CSS values and units. I t explains clearly the EM & REM. EM is the same font-size of the current element.( 1em=16 pixels.) EMs are the most common relative units that you will use in Web Development.

REM-The rem (root em) works exactly the same as the em,except that it will always equal the size of the default base font-size. Just check the MDN Website.
