Obsidian Style Settings Plugin

This plugin allows snippet, theme, and plugin CSS files to define a set of configuration options. It then allows users to see all the tweakable settings in one settings pane. Style Settings allows both toggling classes on and off the body element, as well as setting numeric, string, and color CSS variables.

This CSS Snippet can be used to adjust every CSS variable of the default Obsidian theme.

Configurable settings are defined by comments within CSS files beginning with /* @settings. These comments must contain YAML with name, id, and settings properties. Style Settings will scan all CSS loaded by Obsidian for these comments.

For example, adding this to a CSS snippet in your vault:

/* @settings

name: Your Section Name Here
id: a-unique-id
settings:
    - 
        id: my-title
        title: My Settings
        type: heading
        level: 3
    - 
        id: accent
        title: Accent Color
        type: variable-color
        format: hsl-split
        default: '#007AFF'
    - 
        id: text
        title: UI font
        description: Font used for the user interface
        type: variable-text
        default: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen-Sans, Ubuntu, Cantarell, "Helvetica Neue", sans-serif

*/

will result in:

Each setting definition must be separated by a dash (-). There are 7 setting types.

All settings definitions must have these parameters:

id: A unique id for the setting parameter
title: The name of the setting
description (optional): a description of the setting
type: The type of setting. Can be one of:
- heading: a heading element for organizing settings
- class-toggle: a switch to toggle classes on the body element
- class-select: a dropdown menu of predefined options to add classes on the body element
- variable-text: a text-based CSS variable
- variable-number: a numeric CSS variable
- variable-number-slider: a numeric CSS variable represented by a slider
- variable-select: a text-based CSS variable displayed as a dropdown menu of predefined options
- variable-color: a color CSS variable with corresponding color picker

`heading`

headings can be used to organize and group settings into collapsable nested sections. Along with the required attributes, headings must contain a level attribute between 1 and 6, and can optionally contain a collapsed attribute:

/* @settings

name: Your Section Name Here
id: a-unique-id
settings:
    - 
        id: this-is-a-heading
        title: My Heading
        type: heading
        level: 2
        collapsed: true

*/

`info-text`

info-text displays arbitrary informational text to users. The description may contain markdown if markdown is set to true.

/* @settings

name: Your Section Name Here
id: a-unique-id
settings:
    - 
        id: my-info-text
        title: Information
        description: "This is *informational* text"
        type: info-text
        markdown: true

*/

`class-toggle`

class-toggles will toggle a css class on and off of the body element, allowing CSS themes and snippets to toggle features on and off. The id of the setting will be used as the class name. The default parameter can optionally be set to true. class-toggle also supports the addCommand property. When set to true a command will be added to obsidian to toggle the class via a hotkey or the command palette.

/* @settings

name: Your Section Name Here
id: a-unique-id
settings:
    - 
        id: my-css-class
        title: My Toggle
        description: Adds my-css-class to the body element
        type: class-toggle

*/

`class-select`

class-select creates a dropdown of predefined options for a CSS variable. The id of the setting will be used as the variable name.

When allowEmpty is false, a default option must be specified.
When allowEmpty is true, the default attribute is optional, and may be set to none.

/* @settings

name: Your Section Name Here
id: a-unique-id
settings:
    - 
        id: theme-variant
        title: Theme variant
        description: Variations on a theme
        type: class-select
        allowEmpty: false
        default: my-class
        options:
            - my-class
            - my-other-class
            - and-yet-another

*/

Options may also be given a label:

/* @settings

name: Your Section Name Here
id: a-unique-id
settings:
    - 
        id: theme-variant
        title: Theme variant
        description: Variations on a theme
        type: class-select
        allowEmpty: false
        default: my-class
        options:
            - 
                label: My Class
                value: my-class
            - 
                label: My Other Class
                value: my-other-class
*/
