My online book, Professional Web Typography, gets some minor updates, noticeably the new typefaces. I replaced Adobe Caslon, Myriad, and Source Code Pro with Cardea, Vista Sans, and Fira Mono. Check the colophon.
I separated the chapters that were added the book was completed. I am planning on writing additional chapters when time permits. I also made some updates throughout the book to keep things fresh.
Thanks to readers who have read and supported the book. Your contribution is appreciated.
