The new rich text box with columns is awesome but I want to control column breaks. It shoule work with css, break-inside and break-after, see https://developer.mozilla.org/en-US/docs/Web/CSS/break-inside. So I put this into my custom code for my classes but it wont work. If I take a look at the published page with the inspector the break-properties has a strikethrough and it says unknown property. Anybody knows how to use these css properties with webflow?
