title: Tailwind Classes
|
|
description: Icons system breakdown. Copy values of Icons.

|
|
|
|
Supabase is migrating to use tailwind classes that use CSS properties.
|
|
This is to support the concept of theming, so that:
|
|
|
|
1. It is easy for the team to update the theme without changing 100s of files.
|
|
2. We could offer custom or additional themes in future.
|
|
|
|
## Primitives
|
|
|
|
We (the Supabase Design team ✨) define primitive color values using Figma Variables.
|
|
|
|
- `background`
|
|
- `foreground`
|
|
- `border`
|
|
- `brand`
|
|
- `destructive`
|
|
- `warning`
|
|
|
|
These values are exported from Figma as a .json file and transformed into tailwind utilities through some scripts under `packages/ui/internals/tokens`.
|
|
|
|
Any of these colors are available on any tailwind utility that accepts color. For example:
|
|
|
|
```jsx
|
|
// this uses the default foreground color
|
|
<span className="text-foreground"></span>
|
|
|
|
// this uses the 'light' foreground color
|
|
<span className="text-foreground-light"></span>
|
|
|
|
// this uses the default warning color
|
|
<span className="text-warning"></span>
|
|
|
|
// this uses the '500' warning color
|
|
<span className="text-warning-500"></span>
|
|
```
|
|
|
|
## Shorthands
|
|
|
|
We support shorthand classes for `background`, `foreground` and `border`. For example:
|
|
|
|
- `text-muted` is the same as `text-foreground-muted`
|
|
- `bg-surface` is the same as `bg-background-surface-100`
|
|
- `border-strong` is the same as `border-border-strong`
|
|
|
|
This will stop you from needing to 'double type' the same utlity name.
|
|
|
|
You might notice we use `foreground` and `background` as prefixes, this is only because it is a Design Token standard, where as tailwind uses `bg` and `text`.
|
|
|
|
## Mixing colors
|
|
|
|
Even with shorthands, remember you can use any color. For example, `foreground-light` can also be applied on borders and backgrounds as `border-foreground-light` and `bg-foreground-light`, if needed.
|
|
Similarly, background and border primitives can be used on other tailwind utilities.
|
|
|
|
```jsx
|
|
// use the text light color for some text
|
|
<span className="text-light"></span>
|
|
|
|
// we can use the same color for a background
|
|
<div className="bg-foreground-light">
|
|
<span>I have the same color background as the left example</span>
|
|
</div>
|
|
```
|
|
|
|
## Opacity support
|
|
|
|
All the colors are generated using tailwind opacity, like `hsl(--background-default) / var(--tw-bg-opacity)`.
|
|
This means all the color options in our themes can support opacity rules. For example:
|
|
|
|
```jsx
|
|
<div className="flex gap-3">
|
|
<div className="w-4 h-4 rounded-full bg-surface-300"></div>
|
|
<div className="w-4 h-4 rounded-full bg-surface-300/90"></div>
|
|
<div className="w-4 h-4 rounded-full bg-surface-300/80"></div>
|
|
<div className="w-4 h-4 rounded-full bg-surface-300/75"></div>
|
|
<div className="w-4 h-4 rounded-full bg-surface-300/50"></div>
|
|
</div>
|
|
```
|
|
|
|
## Usage
|
|
|
|
The following tailwind classes are a combination of tailwind utilities and our primitives. They're under development and are likely to change but most are now in use and will probably be permanent fixtures.
|
|
|
|
### Foreground (Text)
|
|
|
|
| Value | Usage |
|
|
| ---------------------- | -------------------------------------- |
|
|
| `foreground-{DEFAULT}` | Default text (**DEFAULT** is optional) |
|
|
| `foreground-light` | Light text |
|
|
| `foreground-lighter` | Lighter text |
|
|
| `foreground-muted` | Muted text |
|
|
|
|
Examples:
|
|
|
|
```jsx
|
|
<div className="text-foreground">/div>
|
|
<div className="text-foreground-light">/div>
|
|
<div className="text-foreground-lighter">/div>
|
|
<div className="text-foreground-muted">/div>
|
|
<div className="bg-foreground-light">/div>
|
|
```
|
|
|
|

|
### Background
|
|
|
|
| Value | Usage |
|
|
| ----------------------------- | ------------------------------------------------------------ |
|
|
| `background-{DEFAULT}` | Main body background (**DEFAULT** is optional) |
|
|
| `background-surface-100` | Panels and surfaces on the same level of the main background |
|
|
| `background-surface-200` | Surfaces that overlap the main content (ex. dropdowns) |
|
|
| `background-surface-300` | Surfaces that are stacked above background-surface-200 |
|
|
| `background-alternative` | Alternative background (inverted) |
|
|
| `background-overlay` | Overlays, Dropdowns, Popovers |
|
|
| `background-control` | Inputs, Radios, Checkboxes |
|
|
| `background-button-{DEFAULT}` | Button default |
|
|
|
|
The `background` part can be omitted when used on the `bg` tailwind utility.
|
|
|
|
Examples:
|
|
|
|
```
|
|
bg-surface-100
|
|
bg-overlay
|
|
bg-alternative

text-background-surface-100
