To reduce the text size of a heading on scroll in Webflow, you can utilize the scroll trigger feature in Webflow's interactions. Here's a step-by-step guide on how to achieve this effect:
1. Select the heading element you want to resize on scroll.
2. Go to the Interactions panel, usually located on the right side of the Designer interface.
3. Click the "+" icon to create a new interaction.
4. Choose the scroll trigger option from the "Trigger" dropdown menu.
5. Set the desired scroll offset. This determines at what point of scrolling the interaction should trigger. You can define whether the offset should be based on the top or bottom of the viewport.
6. Select the "Affect different element" option from the "Affect" dropdown menu.
7. In the following input field, select the same heading element you initially chose. This ensures the interaction affects the heading.
8. Set the initial state styles of the heading element. Here, you can specify the initial font size of the heading. It should be the size you want to start with before the scroll trigger takes effect.
9. Add another step to the interaction by clicking "+ Action".
10. Choose the "Set" option from the "Action" dropdown menu.
11. Specify the styling property you want to modify, in this case, the font size.
12. Set the target value for the font size when the scroll offset is reached. You can make it smaller than the initial state to create a reduction effect.
13. Adjust the easing and duration settings to control the speed and smoothness of the transition.
14. Preview the interaction and adjust the scroll offset and font size values as needed until you achieve the desired effect.
By following these steps, you can create a similar text size reduction effect on scroll, just like the Webflow website. Remember, you can also apply this technique to other elements and modify various properties based on your design requirements.
