Once you've uploaded your theme, it's time to make it your own. While all of your products, collections, pages, and navigation will be configured in the Shopify admin, any changes you make to the look and feel of your store will happen in the theme editor. You'll access it by navigating to Online Store > Themes and then clicking the Customize button beside the theme.
Once inside, you can see that the theme editor is divided into two tabs: Sections and Theme settings.
The Sections tab contains all of the sections that are available to you in Atlantic. Essentially, sections are the building blocks of your store, allowing you to assemble pages from customizable, moveable components. You can add, remove, and reorder sections, as well as access the customization features for each from the Sections tab.
The Theme settings tab lets you make global changes to the look of your store, through settings such as Typography, Colors, and Social media.
Most of the time you spend in the theme editor will be on either the Sections or Theme settings. There are a few other helpful tools to note, as well.
The Theme actions menu attached to your theme name contains a few handy links.
View theme will open a new tab or window to see how the saved content will display from the customer's point of view. This will be called Preview theme if the theme is still in the draft stage.
If you're fluent in Liquid (Shopify's templating language) you can kick your customizations up a notch by digging into the theme's code by selecting Edit code. If not, our support team will be more than happy to put you in touch with someone who is.
Finally, Edit languages lets you both change the language of your theme and checkout, as well as customize the terminology that is used throughout your store.
Above the right-side preview, you can change the device view. This allows you to get a sense of how your store appears in mobile (left), desktop with settings sidebar (center), and full-window desktop (right).
