1. static: the default value, which means no special positioning is performed and the document flow is arranged normally.
2. relative: relative positioning, indicating positioning relative to the element's position in the document flow.
3. Absolute: Absolute positioning means positioning relative to the nearest non-static positioned ancestor element.
4. fixed: fixed positioning, indicating positioning relative to the browser window.
5. sticky: sticky positioning, which means that the element is positioned in the document flow according to the scroll position until it becomes fixed positioning after the scroll reaches a certain threshold.

When using these positioning methods, you can also adjust the position and size of the element through a series of attributes. The specific attributes include:

1. top, right, bottom, left : Indicates the offset of the element relative to the anchor point. It is only applicable to relative, absolute, fixed and sticky positioning methods.
