Your store can have two different fonts.
This font will be most of the text on your website, including paragraphs, links, button text, and badges. The default size for this text is 16px, but you can adjust that to be from 14px - 18px using the range slider setting. In section settings throughout the theme, you'll sometimes have options to make the text larger or smaller for different use cases.
This font will be used for titles throughout the site, and it is always going to be larger than the default text size. Under the "Size" setting for the heading, you can choose a size for the main heading (x-large, large, medium, small), which is the largest a heading will ever display. In section settings throughout the theme, you'll sometimes have options to make the heading text larger or smaller for different use cases.
You also have the option to make heading text all capitalized by selecting the checkbox "Make heading all caps". We recommend that you choose a smaller heading size, like medium or small, if you decide to display your headings in all caps.
