Your Subpage templates allows up to 8 content sections (there are also 6 sidebar sections available on the default two column template).  Each section can contain text, images, etc.

Content > Sections

Content - This is the main content block and supports the content/styles of the page content.

Background Color (HEX) - This color allows you to set the background color of the section and should be a html hex value.  A good reference is https://www.w3schools.com/colors/colors_picker.asp.

Background Image - This serves as the section background image.  This image should be 1,280px in width by the desired height.  The height will depend on the amount of content in the section.  A recommended height would be between 600px and 1,200px (double for retina).

Dark Background - Selecting this checkbox displays the content in white color on top of the site default section background color or dark background image.  

Parallax Background - This option turns the Background Image into a parallax background.

Heading - This content displays above the section content with a white background.  Typically the heading 2 tag would be used, but this section supports all normal content tags, buttons, etc.  To add an icon to a heading 2 tag you will go to the html view you will add the "i" tag with an icon class.  A full list of available icons can be found at http://gbcommunitychurch.monkpreview3.com/_assets/fonts/icons/ (use http://gbcommunitychurch.com/_assets/fonts/icons/ when your site goes live).  Example html: <h2 style="text-align: center;">From the Blog <i class="icon-rss"></i></h2>
