Dividers is a great way to break up different sections of your website page. Remember you do not want to keep adding dividers to page just so you can add all of your content to one page. Keep website design in mind and if you find you are having to continue to scroll down your page and add more content and dividers, it might be time to look at how you can divide the content up in to different pages.
This section shows how when you change the section background color, it will change the color of the divider lines.
I also added two dividers, so you can see this is also a design opion.
