CSS Position Properties

The Position property in CSS is used to represent the location information of an element.

There are three values: static, Absolute, relative. If the element is not explicitly configured with the Position property, the default position value for that element is static.

1, Static: This is to indicate that the element is arranged and nested in the order and the rule should be in the position, at this time set Top,right,left, the bottom property is invalid;

2, Absolute: The location reference point is the most recent configuration of the Position property value is non-static parent node element, if all of its parent nodes are not explicitly configured position property, then the browser window location as a reference, at this time set Top,right,left, Bottom property value is valid;

3, relative: Position reference point is its original position (the element position is configured as static position), at this time set top,right,left, bottom attribute value is valid;

The Z-index property is used to specify the value of the z-coordinate in three-dimensional coordinates (x, y, z), which is 0 by default, can be set to a positive number, or negative, and the higher the value, the higher the z-axis direction.

Note: This property must be valid only if the element is configured with the Position property value of Relative/absolute.
