Difference between offset() and position() Method:
| offset() Method | position() Method |
|---|---|
| The offset() method in jQuery returns the first found position of HTML element with respect to the document. | The position() method in jQuery returns the current position of HTML element with respect to its offset parent. |
| The jQuery UI offset() is relative to the document. | The jQuery UI position() is relative to the parent element. |
| When you want to position a new element on top of another one which is already existing, its better to use the jQuery offset() method. | When you want to position a new element near another DOM element within the same container, its better to use jQuery position() method. |
| The offset() method is mostly used in drag-and-drop functions. | The position() method is used to position an element relative to document, window or other elements like mouse or cursor. |
