0:27 There's also going to be a CSS output if you're going to have any styles in our Svelte application.

0:53 We, as Svelte developers, don't have to optimize so much for performance because all this work is being done by the compiler. If we have any styles in our Svelte application, we're going to get the CSS output as well. We've pre-generated class names. We don't have to worry about that either.
