How can I resolve the issue with the slider mask in Webflow, where it is currently taking the height of the tallest slide and causing empty space in certain slides? I have tried using the CMS feature for the slider, but it is not available yet. I also tried using the finsweet CMS slider, but the height issue still exists.

The slider mask in Webflow typically inherits the tallest slide’s height, which can cause unwanted empty space on shorter slides. Since Webflow’s native CMS Slider isn’t available yet and Finsweet’s CMS Slider doesn't solve the height mismatch, you’ll need to apply a workaround to make the slider height dynamic based on each visible slide.

​

1. Set the Slider Mask Height to Auto

​

• Select the Slider Mask element (inside the Slider component).
• In the Style panel, set Height to Auto instead of Fixed or 100%.
• Also ensure the Overflow is set to Hidden to prevent content spilling.

​

2. Make Slides Expand Based on Content

​

• Select each Slide and ensure:
• Display is set to Block or Flex (vertical).
• Align Items is set to Stretch (if using Flexbox).
• Remove any fixed height setting from the Slide unless absolutely necessary.

3. Use the Slider as a Flexbox Container (Optional Enhancement)

​

• On the Slider element (not the Mask), set:
• Display to Flex.
• Flex Direction to Horizontal.
• Overflow to Hidden.
• This helps the slides maintain their natural height as long as transitions are properly handled.

​

4. Enable Smooth Height Transitions Using Custom Script

​

Since Webflow doesn’t animate slide height based on content by default, inject a small script to adjust the mask height each time the slide changes:

​

• In the Page Settings → Before </body> tag, add a script that:
• Listens to slider change events.
• Sets the Slider Mask’s height to match the active slide.
• Example inline explanation (do not paste raw code):
• The script should: (a) detect the active slide’s height with JavaScript, (b) apply that height to the mask using .style.height, (c) optionally transition the height with CSS (e.g., transition: height 0.3s ease).

​

5. Remove Fixed Slide Layout Settings

​

• Double-check each Slide for:
• Min-height, Max-height, or unnecessary padding/margin that adds vertical space.
• Nested elements (like rich text or images) that may be causing inconsistent slide heights.

​

Summary

​

To make your Webflow slider's mask height adapt to individual slide content, set the Mask’s height to Auto, allow each Slide to size based on its content, and optionally use custom JavaScript to dynamically update height on slide change. Native CMS Slider functionality isn't available yet, and Finsweet's workaround still requires this manual height management.
