Changing a Section’s Background Color on Scroll in Webflow Using Scroll-Based Interactions

 

To dynamically change a section's background color when scrolling in Webflow requires leveraging Webflow's interactions and animations system. This guide will take you through a step-by-step process to achieve this effect efficiently.

 

Prerequisites

 

• An active Webflow account with a project containing a section you wish to animate.
• Basic familiarity with Webflow Designer, including the use of the Style panel and Interactions panel.
• A basic understanding of CSS and how styles are applied to elements.

 

Setting Up Your Webflow Project

 

• Log in to your Webflow account and open the project you’re working on.
• Navigate to the Designer where you wish to apply the scroll interaction.
• Ensure your page has at least one section or div block that you want to affect using scroll interactions.

 

Creating the Section and Initial Styles

 

• Choose the section you want to apply the background color change to or create a new section.
• In the Style panel, give it a class name (e.g., “Scroll-Section”) if you haven’t already.
• Set an initial background color for this section according to your design needs.
• Ensure the section has a sufficient height so that the scroll effect is noticeable.

 

Configuring Scroll-Based Interactions in Webflow

 

• Click on the Interactions panel (lightning bolt icon) in the upper toolbar of the Webflow Designer.
• For the element trigger, you will use the ‘While Scrolling in View’ interaction.
• Click on the element (e.g., “Scroll-Section”) to select it and then click on the “+” to create an interaction.
• Select “While Scrolling in View” from the dropdown menu.

 

Creating the Scroll Interaction

 

• Add a new animation by clicking “+” on the steps section.
• Name your new animation (e.g., "Background Color Change on Scroll").
• Inside the animation timeline, add a “Background Color” change action.
• To do this, click the “+” in the actions and select “Background Color”.

 

Defining Animation Keyframes

 

• Set your first keyframe:
  • Position the scrubber at the start of the timeline (e.g., 0%).
  • Set your initial background color (the same color you set in the Designer initially).
• Add your second keyframe:
  • Move the scrubber to another position on the timeline (e.g., 100%).
  • Set your desired background color at this point of the scroll.
• Optimize the timing and transition to suit the required scroll length and effect.

 

Testing Your Interaction

 

• Exit the interaction builder and switch to preview mode to test the scroll interaction.
• Scroll through the page to observe how the background color transitions as expected.
• Tweak the duration, easing, and scroll position in the Interactions panel if the transition is too fast or too slow.

 

Deploying Your Interaction

 

• Publish your site once the interaction functions correctly in preview mode.
• Check your live site across different devices to ensure the scroll interaction works consistently across various screen sizes.
• Consider optimizing image and script sizes, ensuring that the section’s background effects do not impact page load speeds significantly.

 

By following these steps, you can successfully apply a scroll-based background color change interaction to a section in Webflow. This technique enhances user experience and adds an engaging visual element to your webpage.
