Kendo provides a means to build your theme with SCSS variables in the build process. It would be great if it were possible to have these variables scoped to specific contexts, eg <div class="panel-dark"> receives the panel-dark themes, whereas if it is a child of "panel-light" then it receives the panel-light themes. Some of these kinds of features may be on the way with upcoming Custom Element features eg :part, :theme, but could potentially be possible today by having a style transclusion component, something like <kendo-theme-adjuster [styleCallback]="scssVariableSetter()"><my-content></my-content></kendo-theme-adjuster>. We need to support a variety of component themes simultaneously (not just switch back and forth) within a single app, and would like to not need to manually override all the kendo styles in these situations.
