Descendant selector: You can use a space to denote a descendant selector. This matches all elements which are descendants of a specified element.
Child selector: Use a greater than symbol (>) to select all elements that are immediate children of a specified element.
Adjacent sibling selector: Use a plus sign (+) to select all elements that are adjacent siblings of a specified element. They must have the same parent and immediately follow this element.
General sibling selector: Use a tilde (~) to select all elements that are siblings of an element.

Static: the default positioning of HTML elements.
Fixed: Element is positioned relative to the viewport and stays in the same place even if the page is scrolled. It’s also removed from the document flow. So elements in the DOM pretend like it’s not even there!
Relative: Element is positioned relative to its normal position.
Absolute: Element is positioned relative to the nearest relatively positioned ancestor. If no ancestor with position of relative is found, the element positions against the document body.
