@camperextraordinaire, so sorry man, I forgot to add this:
In the Code Pen link (https://codepen.io/IDCoder/pen/LrQRrw?editors=0010), the red text “Devoted to the design of experiences with code.” auto-types via the javascript typewriter function. In my Github link (https://mtzioncode.github.io), the javascript typewriter function ceases to work, and this sentence, “Devoted to the design of experiences with code.” doesn’t auto-type. Thanks for your help!
