Config Wizard CSS


In order to customize the Configuration Wizard which pops up when End Users are configuring a Solution Instance for their own use, it is possible to upload your own custom CSS in your Partner Account settings.

This will allow you to make sure that Config Wizard screens visible to End Users are in keeping with your branding.

Note: It is recommended that you only make simple styling changes to the Config Wizard. Changing the layout and positioning of items may break the display and may also be subject to being overwritten by product updates. The main purpose of this feature is to allow styling changes to colours, fonts, the shape/roundness of buttons, the thickness of borders etc.

Activate Config Wizard CSS by setting Partner ID

CSS settings are found in the Profile section of the dashboard. To activate the feature you first of all need to set a Partner ID (e.g. the initials of your company):


After saving your Partner ID you will see that the 'Partner CSS Settings' section is activated:


Editing the Config Wizard CSS

You have a choice of either uploading custom css files (using the 'choose file' button), or using the in-app editor and live preview facility (using the 'Edit & Preview' button).

Downloading the pre-populated CSS/LESS file or using the Edit & Preview function will show you the classes available to work with.

You can work with elements according to the following example:

  • partner__item affects all items in the UI
  • partner__item--auth specifically affects all authentication items (e.g. auth drop-down list)

So the following rule could be implemented to affect all authentication items .partner__item--auth > div { color: red; }


The following screenshot shows the live edit and preview when customizing your CSS, and lists the classes which are available:


Testing your CSS

You can create a test project and solution before running our demo app in order to preview and check that your CSS is working as expected.

Note on Caching

Note that once you save changes, it can take up to an hour for CSS changes to fully propagate to your applications globally.

Further Notes

Some further notes when editing CSS:

  1. Avoid using more than 2 levels within a class (for example .partner__screen div h1 span)

  2. Analysis of the source CSS for the End User Config Wizard will show that there are some Tray-specific classes (such as 'header_123ABC123QWE') for elements in the wizard. These are hashed on deployment so will change regularly. Therefore you should not attempt to use these as customizable classes.

  3. Some elements may require the use of !important to take effect. For example:

    background: green!important;

    in order to change the color of the 'Next' button.
