Using HTML Templates

I’m not 100% sure if this is what the site is trying to do, but when I view the localhost version I see things like [column_text] and [/column_text] being displayed in the browser.

I’ve seen similar syntax before that relates to using html templates for quick/easy markup, but I don’t know what to include in the localhost to display this properly without showing code. The localhost has the entire WP backup file structure same as production.
