When writing an article for your website, it can happen that you need to structure your text content for example into multiple columns or into a table. You can achieve this by using special templates that you can find in the text editor of your posts.
Before you start writing the text that you need to separate into two or three columns, click on the Insert Template icon in the administration panel of your text editor. That will open a new window with the option of separating your text into one to three panels, where you can even choose different widths of your columns when using a two panels option. So all you need to do is choose the template you want to use and then click Insert.
After you're done creating your templates and other improvements of your text, don't forget to use as much of the text typography principles as possible.
