Relative Length Units

For some reason I am having trouble understanding this...

Select the link with the class 'more'. Using the rem unit, set its font size back to the base font size of the root html element.

@Jake -

Here's a great article on ems and root ems

Here's a good article on viewport-sized typography

Once you get REM units down, I recommend looking into viewport units; Treehouse's blog has a good write-up about them.

Make sure you provide a px fallback using REM, viewport units, or both. This can be easily done by creating custom functions called mix-ins with CSS preprocessors such as SASS or LESS.

Yeah, REM isn't so bad after all... It's only now since joining treehouse this morning that I actually realized the benefits of using REM units, and I am keen on viewport units.

Going to check it out later today, Thanks Kevin!

Hi All,

I have some issues as well to understand the relative length units. I do believe the video goes over the concepts just that little too fast without going far enough to let the student understand the concept. I have replayed the video so many times now, but it just doesn't help me.

Thanks.
