Hey @qwik3r,
You can’t create a Style Kit directly I’m afraid as the template type is kinda private from Elementor, we simply hack into creating it dynamically in the process. Though this process shall see a change soon. So your best would be “Save as…” on a Style Kit, reset, and then start designing.
As for styling sections differently, we tried that in the past but saw no light as we were limited by functionality within Elementor. However, recently, there are some changes in Elementor v3.0 than can make it possible. We’ll be giving it another shot after we’re done pushing an update along with Elementor in the coming week. We’ve also felt the problem when working with sections.
The plan was to create a set of classes that somehow to take any set of styles on it ??
Stay tuned!
