Riot Web Themes

A place to share themes for Riot Web. Riot's theming documentation has more information on how these work.

These themes are using the relatively basic Riot themeing system which can only change a limited number of colors. For more advanced themes where you want to customize all the colors or things like fonts and button shapes you'll need to use custom CSS files. See https://github.com/dannycolin/riot-compact for an example of a more advanced theme.

How to use themes

There are several different ways to install these. For most users it will be easiest to enable the feature_custom_themes labs flag (currently only on https://riot.im/develop). This will allow you to install themes by pasting in the URL to the raw JSON of the theme. Hopefully in the future this interface will be polished up and enabled by default for all users.

Some other options for installing themes:

If you self host Riot or use Riot Desktop:

You can use these themes by editing your config.json file to include the theme inside of the settingDefaults section like this:

"settingDefaults": {
    "custom_themes": [
        {
            "name": "Example theme",
            "colors": {
                "primary-color": "#9F8652"
            }
        },
        {
            "name": "Another theme",
            "colors": {
                "primary-color": "#526A9E"
            }
        }
    ]
}

To setup a config.json file with Riot Desktop, see https://github.com/vector-im/riot-web/blob/master/docs/config.md#desktop-app-configuration

If you use the matrix-docker-ansible-deploy project

You can enable all of these themes just by setting matrix_riot_web_themes_enabled: true in your vars.yml file. See https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/master/docs/configuring-playbook-riot-web.md#themes for more details.

If you are a Firefox user

You can install Radical which is Riot web bundled as a Firefox add-on. You can edit the config.json file right in the add-on preferences. It works really well, you should check it out. https://addons.mozilla.org/en-US/firefox/addon/radical-web/

Use my Riot Web instance

Alternatively you can use my Riot Web instance which has all of these themes preinstalled so there is no configuration required.

Workarounds

Riot's theme implementation is fairly limited so custom themes might introduce some odd elements. For example, when using ThomCat Black, the selected reaction 'pill' is outlined in green since Riot doesn't give us a variable to control the color that is used there.

To fix this, we have to edit the custom theme CSS file directly, in this case theme-dark-custom.css. cssbeautify-cli is not necessary if your sed-fu is better than the author's is.

cssbeautify-cli -f theme-dark-custom.css > /tmp/theme-dark-custom-sed.css
sed '/.mx_ReactionsRowButton.mx_ReactionsRowButton_selected/!b;n;c\ \ \ \ background-color:var(--accent-color);' /tmp/theme-dark-custom-sed.css > /tmp/theme-dark-custom.css
sudo -u <nginx/apache_user> cp /tmp/theme-dark-custom.css /<riot_directory>/bundles/<bundle_version>/

The results:
