Theming

TutorialKit allows you to customize its appearance to match your brand or preferences. This guide explains how to modify various elements of the interface using CSS variables and file replacements.

Logo

You can customize the logo in the top left corner of the TutorialKit UI by replacing the logo.svg file in the public directory of your TutorialKit project. Supported extensions for the logo are .svg, .png, .jpg, and .jpeg.

If you want to use a different logo for dark mode, you can add a logo-dark file in the public directory. This file is optional, and if it’s not provided, TutorialKit will use the logo file for both light and dark mode.

Styling

In order to customize the appearance of TutorialKit, you can use CSS variables to change the colors of various elements. To do this, you can create a theme.css file at the root of your TutorialKit project and add the CSS variables you want to customize. You need to define the colors for both light and dark mode.

:root[data-theme='light'] {
  /* Light mode colors */
}

:root[data-theme='dark'] {
  /* Dark mode colors */
}

Within these two root selectors, you can define any of the CSS variables mentioned in the following sections.

These tokens can be used to style the colors of the tutorial on a high level. For more detailed customization, you can use the tokens for the individual elements.

Token	Description
--tk-elements-app-textColor	The text color of the TutorialKit app.
--tk-elements-app-backgroundColor	The background color of the TutorialKit app.
--tk-elements-app-borderColor	The border color of the TutorialKit app.

If you want to start with a theme.css file that includes all the available CSS variables you can use the following snippet:

theme.css

:root[data-theme='light'] {
  --tk-background-primary: theme('colors.gray.0');
