Theming documentation (also when using react) - Calcite web

[David_Wilton]

I have tried setting the theme by specifying the theme attribute on the  body but this does appear to work with the react components. Only way I can get it to work is by adding the css class. Can we get it documented how we should be doing this correctly? TBH I couldn't even see it documented on how to apply the theme when using standard, I got it from the youtube video below

Attached is a gif which shows the body attribute not working:

Hi @David_Wilton, You mentioned Calcite Web in the title, however that product is deprecated. The Calcite Design System is the newest iteration, which is the one discussed in the video you provided. The theme attribute was deprecated in version 1.0.0-beta.56, here is the changelog information:

Using the class is the correct way to set the theme. Let me know if you have any additional questions!

Apologies, yes I mean calcite design system.

Would it be possible to get it added to the documentation? There is a section on themes which shows the differences, but no documentation yet on how to apply them.

Thanks for the clarification

Yeah I'll add some documentation for this on the colors foundation page. It is described in the conventions readme but it is a bit hidden.

Thanks for the feedback.

I was able to add a few sections to the FAQ about some of the concepts used in Calcite Components. Here is the one on theming:

Is that what you were looking for?
