CSS positioning is a complex topic, but at its core, there are five key position values: Static: This is the default value, and elements are positioned according to the normal flow of the page. Relative: This positions the element relative to its normal position. Fixed: This positions the element relative to the browser window. Absolute: This positions the element relative to its nearest positioned ancestor. Sticky: This is a hybrid type; it's relative until the viewport reaches a specified point and becomes fixed. Understanding these states is critical for controlling the layout of your page.
