For cheat sheets and other downloadable resources, you’ll be directed to a separate page. From there, you can print the page to a PDF, send it to a printer, or (on a Mac or with a similar browser extension) save it as a PDF. Most resources will be in a dark and light (printer friendly) theme. Both contain the same content. You can also bookmark these pages so that whenever you return, you’ll always see the most up-to-date version. For web-based tools, you’ll likewise be redirected to another page. Creating these cheat sheets in HTML made the process much easier than designing PDFs, since HTML and CSS allow for quicker updates and a more user-friendly experience.
