Hi there

I am after some advice with responsiveness on Webflow. A page I create a while ago, I have just been told is not looking great on a lot of devices and laptops. The video above shows that but i have no idea how to make collums, Photo and text responsive on cms. I have looked online but whatever i try i cant get it to work.

Any ideas?
Many thanks
