Here's a text masking over a video effect in Webflow. This cloneable demonstrates a technique to allow you to clip a background video using text as the screened blending mode. There's also a demonstration using an image rather than a video.

Unfortunately Webflow's native component switches between tabs can be rough on the eyes and somewhat jarring. Using a bit of CSS this cloneable allows for a smooth transition between tabs with visual images by using a small snippet of CSS to override the default tab transition making for a milky smooth transition.
