inspect element as a way to increase your curiosity
One of the best gifts we have as front-end developers is the ability to see how something is implemented by simply inspecting a website and see how the CSS works behind the scenes. Say an interesting effect that you wonder how it was done? Inspect element and the answer is waiting for you. On the other hand, this is not possible for back-end developers, since the source code is gone the moment server-side rendering happens.
