Is there a possibility to see the css classes are used behind the pega screen in pega constellation?

In Pega-UIKT, theme-cosmos version we are able to see the css helper class for the screen in the browser from the inspect option. but in pega constellation instead of showing the css class its just showing the style tag in the browser if we inspect.

Can some one help me on this.

@SreenivasuluV16633502 - In constellation skin rule is not used. You can see the class using developer tools where the css classes are generated runtime. The only option that we have is to use the Rule-UI-Theme instance. You can find all the configurations currently supported as a part of theme rule in the below link.

Hi @PEGARIPPLE

Thank you for sharing info.

In pega non constellation application, we are able to add custom css for fields, etc. but in constellation i have gone through the theme rule and design document but didnt find the way add custom css. And more over theme rule looks like predefined css helper class.

Please see this earlier discussion that is relevant here:

[Can we customize theme rule in pega constellation? | Support Center](https://support.pega.com/question/can-we-customize-theme-rule-pega-constellation)

The recommended best practice for updating constellation themes is via App Studio using the Themes landing page. If required you can gain a more granular level of control over your theme by manually editing the theme JSON file in Dev Studio to update individual design tokens as described in the documentation referenced.
