// This file is the central place where we declare
// which variables are part of the "mediawiki.skin.variables.less"
// API that core and extensions can use in their style modules.
//
// The initial values are intended merely as fallback to allow
// forward and backward compatibility to allow new variables
// to be defined without breaking existing implementations by
// skins.
//
// @since 1.36
// Add `@since` line above every added variable (block) per MediaWiki version.
//
// == Instructions for skins ==
//
// In skin.json, add:
//    "SkinLessImportPaths": {
//        "skinname": "resources/mediawiki.less"
//    }
//
// Create a file called resources/mediawiki.less/mediawiki.skin.variables.less, which starts with:
//    @import 'mediawiki.skin.default.less';
// followed by any overrides for these variables, e.g.:
//    @width-breakpoint-desktop: 1234px;

// == Breakpoints ==
// Minimum available screen width at which a device can be considered a mobile device.
//
// Many older feature phones have screens smaller than this value.
@width-breakpoint-mobile: 320px;

// Minimum available screen width at which a device can be considered a tablet.
//
// The number is currently based on the device width of a Samsung Galaxy S5 mini and
// is low enough to cover iPad (768px).
@width-breakpoint-tablet: 720px;

// Minimum available screen width at which a device can be considered a desktop.
@width-breakpoint-desktop: 1000px;

// Wider desktop breakpoint
// @since 1.37
@width-breakpoint-desktop-wide: 1200px;

// == Size properties beyond Box Model ==
// These are the center point for skin sizing.
// Note that these are recommended to be set in relative units like `em` in order to let users
// override with own browser font size preference.
// Font size
@font-size-base: 1em;

// Line Heights
@line-height-base: 1.6;
@line-height-heading: 1.3;

// with name `*-input-binary`.
@line-height-label: 1.5;
