To make an element sticky and relative in Webflow, you can follow these steps:
1. Select the element you want to make sticky and relative.
2. In the Style tab of the right-hand panel, locate the position property.
3. Change the position property from its default value of static to relative.
Note: Making an element relative is important as it defines the initial position of the element before it becomes sticky.
4. Next, locate the interaction settings by clicking on the plus icon next to the element or by going to the Interactions tab.
5. Create a new interaction by clicking on the "+" sign and select "While scrolling in view" as the trigger.
This trigger allows you to add interactions that are triggered as the element enters or leaves the viewport.
6. Under the "Start" section of the interaction, select "Affect different element" and choose the element you want to affect. This will typically be the same element so that it affects itself.
7. In the "Affect" dropdown, select "Move" and choose the option "Element is sticky".
This option enables the sticky functionality for the element when it is within the viewport.
8. Set the desired position for the sticky element. You can choose to make it stick to the top, bottom, left, or right of its parent container.
For example, if you want the element to stick to the top of its parent container, choose "Top" in the "Position" dropdown.
9. Adjust the offset if necessary. The offset determines when the element becomes sticky, for example, when it is 100 pixels scrolled into view or at the very top of the viewport.
10. Optionally, you can add animations or styling changes under the "Finish" section of the interaction. For example, you can fade in the element or change its background color when it becomes sticky.
11. Finally, preview your site and scroll to see the sticky behavior in action. The element you made sticky should now stick to its relative parent container according to the specified position and offset.
Remember to test the behavior across different devices and screen sizes to ensure a consistent experience.
