In the recent blog post on how to make a web part works with different section backgrounds using CSS variables, I already covered. At the same time, this works perfectly for just regular web parts. There are specific scenarios, where this approach fails.
Over the last couple of days, I banged my head against the wall. I hate when things don’t work as expected. On the other hand, I love challenges.
The thing we are talking about the documentation on “Supporting section background“. To be clear, the documentation is correct. It works as described. The issue I and many others have with this documentation it does not apply to your project.
Its been a while since the last release for my toolset for Theming in SharePoint development. I work on a product, and I have to make sure that the web part design is flexible enough to work great with any SharePoint applied theme. I discovered many changes in the currently available theme slots.
The support in case of SASS variables in your standard SharePoint project is limited. It was time to update my tool, but it comes with more great features that only SASS variables.
