There is a known method of creating a different shapes using CSS clip-path property. Unfortunately, it still not supported by Edge and IE11 browsers.
Here is a method that will let you create highly customizable hexagon shape in Webflow. It can be filled with colors and gradients as well as with images and videos.
Main shape/form will be created by 3 rectangles-divs. Each of them we will turn in a certain angle, but main goal is get a 60 deg angle between hexagon's sides.
External div (hex).
Proportion between width and height of this div will define the angle of the hexagon itself:
After you decide your hexagon's angle and add the 1st div hex with its size, make it position: relative. Then go to Transforms settings and Rotate it on -30deg on Z-axis.
First internal div (hex-1).
Inside the div hex create the div hex-1 and apply settings:
(All next divs will have the same position and size).
Then go to Transforms settings and Rotate hex-1 on 60deg on Z-axis.
Now if you will go back to the hex and set its overflow: hidden you will see how it will start to create hexagons sides
Second internal div (hex-2).
Inside the div hex-1 create the div hex-2 and again apply settings:
Then go to Transforms settings and Rotate hex-2 on -120deg on Z-axis.
With settings overflow: hidden applied to hex and hex-1 you will get a hexagon shape
Make hex-2 overflow:hidden and now you can style it by adding some colors or gradients. You also can add additional div inside the hex-2 for the content (text, image, bg-video) but don't forget that it needs to be rotated 90deg on Z-axis as well as have position: absolute. Width and height of that div or content can be adjusted accordingly to your needs
