Theme: colours, fonts and page width
Pick a ready-made palette or set your own colours and fonts once, and the whole storefront follows. Add a favicon, then publish.
The theme holds the colours, fonts and page width that every page uses. Change a value once and the whole storefront follows, so your buttons, links and backgrounds always match. It also holds your favicon, the small icon in the browser tab.
Before you start#
- Use a desktop-size screen, at least 1024 px wide. The theme editor shows a message on smaller screens.
- You need design edit permission to change the theme, and design publish permission to publish it.
Open the theme editor#
Open Design, find the Store theme card (it says Theme & colours or Theme settings), and press it. You can also open it from the builder: More > Theme colours and fonts.
Choose colours#
- 1
Look at the palettes
Under Ready-made palettes pick a look in one click. Use the palette group filter, and Preview palettes in Light or Dark.
- 2
Use one
Press Use this palette. It fills in every colour for light and dark mode. Nothing goes live until you publish.
- 3
Or start from a preset
Start from a preset fills in the colours, fonts and page width of a ready-made look. Other values you already set stay.
- 4
Adjust by hand
Open Customize colours (or Advanced: adjust colours yourself) and change single values. Switch Colour mode between Light and Dark to set each one.
- 5
Publish
Press Publish. If there is nothing new, the editor says "Nothing new to publish".
What a value can look like#
| Kind of value | Allowed |
|---|---|
| Colours | #hex, rgb(), hsl() or a colour name |
| Fonts | font names and commas |
| Sizes | a number with px, rem, em or % |
A value that is not allowed is refused with a message, so a typo cannot break your storefront.
Favicon#
Under Favicon (browser tab icon) pick a square PNG, JPEG, WebP, GIF or ICO picture from your media library. Without a favicon, browsers show no icon. Remove favicon takes it away again.
Custom CSS#
Advanced users can add Custom CSS. It applies only to your live storefront, after publishing. These parts are removed when you publish: @import, remote fonts, scripts and outside images. Images must come from your media library. The editor lists what was removed.
Common problems#
The theme editor will not open
It needs a screen at least 1024 px wide. Use a computer or a tablet held wide.
My colour was refused
Write colours as #hex, rgb(), hsl() or a colour name. For sizes use a number with px, rem, em or %.
My custom CSS partly disappeared
Imports, remote fonts, scripts and outside images are removed on publish. Upload pictures to your media library and use those.
