I'm a casual so don't take this post as authoritative or anything, but I feel like people are forced to use frameworks to do anything more complex than a static website meant for desktop only. For example, to make a fully responsive website that adapts from desktop to mobile and vice versa and can dynamically create forms and stuff, there's no one place to go and see a SUPER OFFICIAL STANDARD OF HTMl/CSS way to do it. There are some official resources like w3school and mozilla, but they're only good for really simple things. You find a bunch of scattered guides around the web, none of them really explaining the choices in their settings very well or at all. So as a beginner, I feel like I am just throwing shit at a wall and hoping something sticks and works, until I find some other setting from a different guide to do some other thing that breaks the first feature. With modern frameworks, you can achieve some structure and order, because someone else did all the boilerplate and groundwork so that you can just make a damned website like you wanted to do instead of floundering around from tutorial to tutorial.
