Editing Pages
Most day-to-day changes use a page's Headline, Content, Excerpt, Files, Social media settings and Tags. You do not need to edit theme code.
Open Website pages, find the page by its name or slug, and check that you are editing the intended website. The current development website shares the public theme project with other examples.
Use Page fields and images to find the field you need, then follow the relevant module guide. For a new landing page, start with Building a page from modules.
