We do this at my job. Do you have any good articles that describe clearly why this is bad? On the surface I assume it’s because you need to load all the js, create the dom, and then apply css in that order instead of just having a separate file for css loaded quickly at the beginning and letting the dom load in after. But is there a benefit to css in js where only the css used in the components your rendering is loaded? Like an automatic code splitting for css?
