To specify an element's font size, use the CSS
Remember from our Fundamentals of Length lesson that we can use pts, px, %, em, or vw.
Use pts and px if you want to be exact, and use %, em, or vw to have your font be relative to another element. Additionally, we can use vw and vh for the size to be relative to the user's viewport window.
Text size should almost never be specified in pixels. Rather, we should use a relative unit (eg. em), to ensure proper contrast. Remember the magic formula:context / default = result
