Customizing the Look and Feel

Introduction

Mobiscroll components are shipped with a ready-to-use, carefully crafted design, with the ability to adapt to the platform where they are being used. The available themes are:

• ios and ios-dark - theme matching the iOS platform look & feel
• material and material-dark - theme matching the Material Design specification
• windows and windows-dark - theme matching the Universal Windows platform look & feel

The Mobiscroll package is shipped with a pre-built css file, once it's added to your project, the bundled themes can be used right away.

While the provided pre-built themes are enough in many use cases, most of the times on top of adapting to a specific platform, you'd also like to match a brand or color scheme. Mobiscroll provides various ways to achieve this:

• Override the Sass color variables - the straightforward way to change the colors in one place throughout the application.
• Create custom themes using Sass - use this, if you need multiple themes with different color variatons, in case you have pages with different colors, or you'd like to users to customize the colors of your app.
• Create custom themes using the theme builder - the custom themes can be also built using out theme builder, on a graphical user interface, without any coding, or the need for Sass support in your project.

To work with the first two methods, you need to have Sass support configured for your project.

If you're not using the tools above, you can use any existing Sass tooling to compile the scss file into css (such as gulp-sass or grunt-sass). The simplest approach is to use the node-sass CLI - you simply run:

$ node-sass src/my-theme.scss dist/my-theme.css

Once Sass support is set up, instead of the pre-built css file, you need to import the provided scss file.
If using the mobiscroll npm package:

@import "~@mobiscroll/javascript/dist/css/mobiscroll.scss"

@import "./path/to/mobiscroll/css/mobiscroll.scss"

Override the Sass Color Variables

A convenient way to customize the colors of the Mobiscroll components is to override the Sass color variables.

Let's say your branding uses a nice red accent color, and you'd like that color to appear on the Mobiscroll components as well, while still using platform specific themes (e.g. ios on iOS devices, material on Android devices, and mobiscroll on desktop). You can override the accent color for every theme:

$mbsc-ios-accent: #e61d2a;
$mbsc-material-accent: #e61d2a;
$mbsc-mobiscroll-accent: #e61d2a;

@import "~@mobiscroll/javascript/dist/css/mobiscroll.javascript.scss"

Of course you can customize more than just the accent, like background, text, primary, secondary colors, etc. Here's the complete list of the Sass variables being used:

Create Custom Themes Using Sass

If you'd like to use multiple color variations for the Mobiscroll components, the solution is to create one or more custom themes. A custom theme is a variation of one of the built in themes, referred as the base theme.

To create a custom theme using Sass, you can use the provided mbsc-custom-theme function, which can be called after the mobiscroll scss file has been imported:

@import "~@mobiscroll/javascript/dist/css/mobiscroll.scss"
$colors-ios-custom: (
    button: #6D8764,
    accent: #6D8764,
    background: #F7F7F7,
    text: #000000
);
@include mbsc-custom-theme('ios-custom', 'ios', $colors-ios-custom);

Before you can use the custom theme, you will also need to register it in your javascript / typescript code. This can be done after the mobiscroll resources has been loaded, but before using any of the components. Make sure to use the same name which was specified to the Sass function, and specify the same base theme as second parameter.

mobiscroll.createCustomTheme('ios-custom', 'ios');

You can now specify the newly created theme to any Mobiscroll component using the theme setting:

mobiscroll.eventcalendar('#my-calendar', {
    theme: 'ios-custom'
}

Create Custom Themes Using the Theme Builder

If Sass support is not available in your project, or you prefer a visual theme editor, you can use our theme builder to create custom themes.

The theme builder is very easy to use, no coding is needed, you just choose the colors, and save the custom theme. Using our download builder you can select one or more custom themes to include in the package.

You can find more information on the theme builder features and usage here.

Custom Themes with Light and Dark variants

To use custom themes together with the themeVariant option (which controls whether the light or dark variant of a theme will be used), make sure to create two custom themes, where the dark version has the same name as the light one, suffixed with '-dark', e.g.: 'my-theme' and 'my-theme-dark'.

How to use custom themes with NPM packagess

Starting from version 4.7.0 the NPM packages are shipped with SCSS mixins which makes it possible to create custom themes programmatically. To create a custom theme, make sure to load the SCSS file from the NPM package. After that you can create a custom theme like this:

@include mbsc-custom-theme('ios-custom', 'ios', ('button': #6D8764, 'background': #f7f7f7, 'text': #000000, 'accent': #6D8764));

Custom themes needs to be registered in the javascript / typescript code as well, once the Mobiscroll modules are loaded:

mobiscroll.createCustomTheme('ios-custom', 'ios');
