Style Guide

This website is a React app built on the Next.js framework with TailwindCSS. I've made it easy for you to duplicate my styles. You can copy and paste the CSS variables into the globals.css file of your codebase. You'll need to have shadcn/ui set up for semantic styling of components to work out-of-the-box. Not using a framework? I've included agnostic tokens you can use for your own styling.

Themes

Dark mode

This website uses next-themes to manage light & dark styles and match them to system preferences. The useTheme hook is used to set and access the current theme and a ThemeProvider is used to wrap the root layout.

CSS variables

Syntax

CSS variables are defined without the hsl() colour space function according to TailwindCSS guidelines.

Paste desired variables into your code

globals.css

Semantics

For the following CSS variables:

Primary button colours (dark)

button-primary

--primary: 263.4 70% 50.4%;
--primary-foreground: 210 20% 98%;

The background variable is used for the background colour of the button and the foreground variable is used for the text colour.

Naming

The background suffix is omitted when the variable is used for the background colour of the component.

The background colour of the following Button styled with Tailwind utility classes will be hsl(var(--primary)) and the foreground colour will be hsl(var(--primary-foreground)).

Check the shadcn/ui Theming docs for full details on the semantic use of variables.

Custom variables

The selection variable is used for the background colour of the selection highlight. The selection-foreground variable is used for the text colour of the selection highlight.

Want HEX or RGB colours instead?

🤓 I thought you'd never ask.

Tips

Click a cell value to copy the colour to your clipboard. Toggle between light and dark themes in the header or mobile menu to see the relevant colours.
