MB over-engineered that book. Example: look at the paragraph that stars “But I don’t have visual skills” on this page: https://practicaltypography.com/why-does-typography-matter.h...

Notice how the open quotation marks hang into the left margin. There’s been some recent work with CSS to make this automatic, but that’s newer than this book and support is spotty. MB made it happen with a (iirc) custom filter inside the Pollen setup he made for this book. Wild. And beautiful.
