Lastly, and of fairly great personal importance, Jekyll allows me to customize the site exactly how I want it. And that level of control is not only better for my meticulous personality, but for you, the reader. Text is easier to read, larger and more consistent across desktop and mobile. Fonts are hand-picked to match my personality and that of the books.
In short, it’s just better. I hope you like it.
