Exactly. What is the react/vue/html/css alternative for this? Because when I look around, I find ways of doing it but people generally do not seem to use them so they end up being abandoned. There is no reason why it cannot be simularly easy, but, as far as I see, people using these technologies like to keep things complex for the design-challenged among us.
