Moodle App Remote Themes Upgrade Guide

In the following guide, you will learn how to migrate your styles from an older version of the app.

However, keep in mind that not all your users will be using the latest version. We recommend that you keep your old CSS rules for older versions as indicated in the Before starting the migration section. By doing so, users who haven't updated the app will continue seeing the same styles they had until now.

Depending on which version of the app you're upgrading from, you'll need to go through multiple version upgrades. This guide is divided by version ranges, so you should be able to start with your current version and build up from there.

Before starting the migration​

We recommend prepending all conflicting CSS rules with the specific version they are targeting.

For example, for a CSS stylesheet that targets both 4.0 and 4.1 versions, you should do the following:

html.moodleapp-4-1 {
    --ion-color-primary: red;
}

body.moodle-app-4-0 {
    --ion-color-primary: green;
}

You can use these classes to target specific major and patch versions as well, so for example version 4.1.0 ships with moodleapp-4, moodleapp-4-1, and moodleapp-4-1-0 classes. You can also use ionic versions to filter styles, such as ionic3 or ionic5.

caution

Notice that mode and version classes moved from the body tag to the html tag in version 4.1. Learn more about this when upgrading from 4.0 to 4.1.

How to upgrade my theme​

You can follow the same process that is documented in the Moodle App Remote Themes page.

Make sure to read it in order to understand how to style your application for newer versions of the app. If you're upgrading your styles, it is likely that the documentation has been updated since you read it. So we recommend taking a look even if you're already familiar with Remote Themes.

4.0 to 4.1​

There is only one thing to look after when upgrading to 4.1, so it should be a relatively quick process.

Mode classes​

Starting in 4.1, mode and version classes have been moved from the body tag to the html tag. This change arose from a bug on derived CSS variables, and it should be fairly straightforward to make.

4.0
body {
    --core-header-toolbar-background: red;
}

body.dark {
    --core-header-toolbar-background: green;
}
4.1
html {
    --core-header-toolbar-background: red;
}

html.dark {
    --core-header-toolbar-background: green;
}
info

In order to avoid breaking existing styles, version 4.1 will continue adding version classes both to body and html tags. But using the classes from the body tag is considered a deprecated approach, and won't be supported in future versions. So we recommend that you update your Remote Themes now.

3.9.5 to 4.0​

There haven't been any breaking changes from 3.9.5 to 4.0 in terms of theming functionality, but the UI of the application has changed drastically so we recommend going over all the customisations to see that they are still relevant in the new version.

3.9.4 to 3.9.5​

This upgrade requires more changes than usual because the Moodle App was upgraded the underlying Ionic framework from version 3 to version 5, which introduced many breaking changes.

Windows Phone​

Starting with this version, Windows Phone is no longer supported so you should remove all styles using Ionic classes ending with -wp since they are no longer necessary.

CSS variables​

Starting with this version, it is possible to use CSS variables to make easier customisations, so it's likely that you won't need to override as many styles as before.

You can see some examples in the sections below, and you can also look at the theme file to find some of the main variables of the app.

Colors​

The main color in the app is Moodle Orange, but you can now change it by using the --primary variable. This will probably reduce the CSS you are applying right now, but this only covers the main color.

For other colors, check out the colors section in the main documentation.

Header toolbar​

Border width and color (new)​

On the header toolbar, we've added a bottom border that you can disable.

More page​

Icons​

The icons in the More page can now easily change their color:

3.9.4
page-core-mainmenu-more ion-icon {
    color: red;
}
3.9.5
page-core-mainmenu-more {
    --core-more-icon: red;
}

To change a color on a particular icon, you'll have to use the class of each handler. For example, to change the color of the folder icon on the menu item named Files:

3.9.4
page-core-mainmenu-more .ion-md-folder,
page-core-mainmenu-more .ion-ios-folder {
    color: red;
}
3.9.5
page-core-mainmenu-more .addon-privatefiles-handler ion-icon {\
    color: red !important;
}

Item border color​

3.9.4
page-core-mainmenu-more .item-block.item-ios .item-inner,
page-core-mainmenu-more .item-block.item-md .item-inner {
    border-bottom-color: red;
}
3.9.5
page-core-mainmenu-more {
    --core-more-item-border: red;
}

The dividers background color can now be overridden using --spacer-background:

3.9.5
page-core-mainmenu-more {
    --spacer-background: blue;
}

Login page​

You can now personalise some colors in the Login page, but keep in mind that this only includes the credentials page (the one after you select the site).

3.9.5
body {
    --core-login-background: red;
    --core-login-text-color: blue;
    --core-login-input-background: green;
    --core-login-input-color: yellow;
}

Messages page​

Message discussion page, including chat activity and comments:

3.9.5
body {
    --addon-messages-message-bg: white;
    --addon-messages-message-activated-bg: gray-light;
    --addon-messages-message-note-text: gray-dark;
    --addon-messages-message-mine-bg: gray-light;
    --addon-messages-message-mine-activated-bg: gray;
    --addon-messages-discussion-badge: orange;
    --addon-messages-discussion-badge-text: white;
}

You can also make some modifications on the input field:

3.9.5
body {
    --core-send-message-input-background: gray-light;
    --core-send-message-input-color: black;
}

Full example​

This is a full example showcasing how to handle multiple versions:

3.9.4 and 3.9.5
/* ----- Ionic 5 styles ----- */

body.ionic5 {
    --core-header-toolbar-background: red;
}

/* Dark mode */
body.ionic5.dark {
    --core-header-toolbar-background: blue;
}

/* iOS only */
html.ios body.ionic5 {
    --core-link-color: green;
}

/* Android only */
html.md body.ionic5 {
    --core-link-color: yellow;
}


/* ----- Ionic 3 styles (legacy) ----- */

body:not(.ionic5) .toolbar-background {
    border-color: #004C9C;
    background: #004C9C;
}

As you can see we recommend to always add body.ionic* to start the CSS selectors, you can also use :root body.ionic5 or even html before body.
