How do Static, Relative, Absolute, and Fixed Positioning Differ in CSS?

Static vs. Relative Positioning in CSS

Static positioning is the default positioning for HTML elements. Elements with static positioning are displayed according to the normal flow of the page, regardless of any left, top, right, or bottom rules.

Relative positioning, on the other hand, allows you to specify an offset relative to the element's normal position in the HTML flow. This enables you to move an element to a specific location while maintaining its place in the document's layout.

For example, you can use relative positioning to move a textbox within a div to a certain spot in relation to its normal position within the div.

In contrast, there is also absolute positioning, which allows you to specify the exact location of an element relative to the entire document or the first parent element that is relatively positioned. With absolute positioning, elements are removed from the HTML flow and can be placed anywhere on the page.

Additionally, fixed positioning restricts an element to a specific position in the viewport, even when the page is scrolled. Fixed-positioned elements are also removed from the HTML flow, but they are not bound by the viewport and will not scroll with the page.

To summarize, static positioning maintains the normal flow of elements, while relative positioning allows you to move an element within the flow and absolute positioning allows you to place an element at a specific location in the document. Fixed positioning removes an element from the flow and restricts it to a specific location in the viewport.
