The store's logo provides branding for a site and also a link to return to the home page.
Add a logo to the header
By default, Grid will display your store name as your logo. To replace it, click the Select image button and select the file you'd like to use. An image that is 200 x 200px and in JPG or PNG format is ideal for this feature.
Choose a logo layout option
Under Logo layout, you'll select the positioning of your header contents. As you can see, the Default layout centers your store's name/logo and navigation and stacks them one above the other.
The Compact center option centers your store's name/logo and aligns your navigation to the left.
The Compact left option aligns your store's name/logo to the left and centers your navigation.
Include logo when sticky header enabled
If the sticky header option is enabled, you can Show logo image in sticky header as well. This is a smaller version of your logo that will appear to the left of your navigation in your sticky header and provide a link back to the home page.
