Study Notes
CSS Units
-
rem (root em) is a CSS unit that is relative to the font size of the root element (usually the
<html>element). - em is a CSS unit that is relative to the font size of the parent element.
HTML Elements
-
Inline elements do not start on a new line and only occupy as much width as necessary; examples include
<span>,<a>, and<strong>. -
Block-level elements start on a new line and by default occupy the full width available; examples include
<div>,<p>, and<h1>.
Display Properties
- The default display value of a block-level element is typically "block," which causes it to begin on a new line and extend the full width.
- In contrast to inline elements, block-level elements create line breaks before and after themselves, differentiating them visually in layout.
Default Font Size
- The default font size for the root element in CSS is commonly set to 12px, which can be used as a reference for calculating other font sizes using rem or em units.
