Discover the power of the CSS Bottom Property, a versatile tool that modifies an element’s vertical position. This property is instrumental in defining the distance of an element from the viewport’s bottom, offering precise control over your webpage layout.
- If the position value is fixed or absolute, then the element adjusts its bottom edge with respect to the bottom edge of its parent element or the block that holds it.
- If the position value is relative then the element is positioned with respect to its own current bottom edge.
- If the position value is sticky then the element adjusts the position which is relative when the element is inside the viewport & its position will be fixed it is outside of the viewport.
- If the position value is static then the element does not have any effect due to the bottom property.
Syntax:
bottom: auto| length| %| initial| inherit;
Property values:Â
- auto: This is the default value of the bottom property. It sets the bottom property based on the browser ie., the browser will decide the bottom edge position.
- Length: It sets the bottom edge position in px, cm also negative values are allowed.
- Percentage: It sets the bottom edge position in % of the containing element. It accepts the negative values.
- initial: Itis used to set an element’s CSS property to its default value. The initial keyword can be used for any CSS property, and on any HTML element.
