CSS Units of Measurement [rem, em, vw, vh, px, %]

There are about 15 CSS units of measurement compatible with most browsers. We are going to cover all of the ones that you will use in real life. We'll cover absolute units like pixels (px) and relative units like percent (%), viewport width (vw), viewport height (vh), and the ones that I get the most questions about, rem and em. I'll clearly explain how they work and when you should and should not use them.

There is a CSS unit that I left out of the video, and that is fractional units (fr). These are specific to CSS Grid. I have a video on that subject that goes into detail on fr units.

# rem
5:49 => 1 rem (default font size of most browsers is 16px);
6:31, 6:41 => change the default html font size to 10px (better to set it in rem);
8:37 => rem is accessibility friendly;
9:00 => the reason why it is accessibility friendly;

# em
8:06 => relative to the font size of the element (the more nested, the crazier it would be);
