I am working in Wappler Beta 7.0-b28.
I created a new project, however, the content is not visible in the editor. Also, the Text & Background Color options are all white & even after applying these Font Color & Background Color the page opens with default state.
In the below code, i have applied primary for H1, primary-emphasis for Paragraph & btn-primary for btn1, however, when the page is run none of the style is applied:
Also check within the Content page that the bootstrap tags have been added to it (first line in the page at the top)...
<!-- Wappler include head-page="layouts/somelayout" is="dmx-app" id="someappid" appconnect="local" bootstrap5="custom" .......... -->
Can see you have the 'weird' problem whereby the Properties Panel for the page is not showing the colors for the text classes (the panel on the right of the Design area).... I can't find the Bug Report but this was reported some time back and thought it was resolved?
