It is possible to add in columns. Probably the best way to go about that is with a plugin like Column Shortcodes (https://wordpress.org/plugins/column-shortcodes/). This one adds a new button to your editor that lets create columns of various sizes. That’s how I would go about creating them.
I see now at the top of the page to edit that there is a button I can click to decide how many columns and where to place the column but I must be doing something wrong. It doesn’t seem to be changing anything. I’ve tried placing the code both before and after what I want in a particular column. Can you help?
Thank you. I’m not sure I’m doing this in the right section. I’ve attached a picture of the page I’m working on. I see the little button on the top next to add media. Do I click there? I only see one third first and one third last. Nothing for the middle … that I can see.
