You are right, you taught me to clean it. I have one issue I couldn’t fix and other one that I don’t understand.
Analyzing html in tribute page, there is an error “The value of the href attribute … must be relative.” searching in codepen documentation it states that “Always link to external assets via fully qualified URLs” as the one I have. So I don’t know how to fix the error.
Analyzing html in Survey Form, it force me to close <option> tag inside the <datalist> form element. I fixed it, but it is confusing as in w3 reference for datalist they don’t close <option> tags.
