Maker - Using the theme editor
Once you've uploaded your theme, it's time to customize it to suit your needs. 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. Access in your store admin Online Store > Themes and then clicking the blue Customize theme button in the top right of your screen.
The Theme editor is divided into to two tabs; Sections and General settings.
Sections are the building blocks of your store, allowing you to assemble pages from customizable, re-orderable components. You can add, remove, and reorder sections, as well as access the customization features for each from the Sections tab.
The content on your homepage is made up of dynamic sections, meaning you can add and arrange as many as you want and fixed sections for elements like the header and footer.
The General settings is where you can configure the design styles for the store, including layout settings, typography and colors. You can also find layout settings and connect social media accounts.
Maker comes packaged with three different theme styles that have pre-defined colors, fonts, and styles - check out the demos Books, Food and Kickstarter.
To select the theme style you would like to use in your store, click over to the General settings tab, then scroll all the way to the bottom to the Change theme style button. Here, you can preview the theme styles and select the one that's right for your store.
Note that applying and saving a new theme style will overwrite your current style settings, however you will not lose any content from your store. It's always a good idea to make a backup copy of your theme before you start making customizations. Use the duplicate copy as your working version until you're ready to publish it.
