I am using Template Toaster to create WordPress templates. Now that my template is exported into WordPress I would like to edit the content of my WordPress page to have multiple columns. I can see in Template Toaster in the content section there can be multiple columns. It also looks like I can edit the template for these columns by going into Post Properties > Columns. I do not want to reinvent the wheel with the CSS if I do not have to, but I'm having trouble finding the CSS that describes using columns in the content of the page so that I can use it in my HTML when editing my WordPress page.
Any advice on how the CSS for using columns in the content/post is labeled would be appreciated.
