How to build a blog.
Use the content button from the black menu bar to create a new blog.
Start with a good headline and then bring content blocks into the page.
You can choose either narrow or wide field by clicking on the blue customize button.
Center Style
I like to make it easy for my audience to read my blog by using a narrowed, center style. I get this style by dragging the three column block onto the page, deleting two and stretching the remaining one to the center.
