Understanding the Concept of Absolute and Relative Positioning in CSS
Absolute positioning allows you to place an element at a specific location relative to its nearest positioned ancestor or the document. On the other hand, relative positioning moves an element from its normal position but keeps it within the flow of the document.
Differences Between Absolute and Relative Positioning
- Absolute positioning The positioned element is removed from the normal document flow.
- Relative positioning The positioned element remains within the normal flow of the document but is adjusted to an offset relative to its original position.
- Absolute positioning Requires a value for both the top and left properties to be set.
- Relative positioning Only requires setting the position property, and the offset properties (top, right, bottom, left) are relative to its original position.
- Absolute positioning Can cause layout issues if not used carefully as the positioned elements can overflow their containing block and affect other elements on the page.
- Relative positioning Doesn’t have such layout implications, as it only moves the element from its original position without affecting the rest of the layout.
