You have two Subpage Templates, which you can use throughout your site as many times as you'd like.

• Subpage Default - This is the default template for your site. This is a two column layout, with the page content on the left and a sidebar on the right. If the page is added to the site navigation, then an auto-generated navigation will display in the sidebar. With this layout, you can use both sidebar and fullwidth sections.
• Subpage Fullwidth - This layout displays your content fullwidth on the page and includes 9 full-width sections

Go to Content > Pages > Add a New Page (or select an existing page)

When creating a new page, the "Template" field will have the "Subpage Default" template selected as the default. You can select the dropdown menu to change to the "Subpage Fullwidth" template, if needed.

The page will automatically display in the header image area. The checkbox "Hide Page Title" removes the title from the page. 

The page description field is optional and can also be used to help with SEO. 

This fields allows you to manually add a class to change the header/billboard options. If more than one class is used, you must include a space in between the classes.  Lowercase is required.

• overlay - adds a dark overlay to your header image or video
• large - changes to a larger header image and the size requirements will increase to 2,732px wide by 1,564px tall
  
• right - moves the header text box to the right
  
• left - moves the header text box to the left

This will add content overtop of your static header image or background video. This works the same as the page content field, so you can include text, buttons, etc. The text will display centered as the default.

If this field is used, the page title and header tagline will automatically be hidden.
