these are some things i find useful in my web adventures
https://www.w3schools.com/ - w3schools is really helpful for figuring out how to code, especially if you have almost no experience like myself
https://htmlcolorcodes.com/ - find hex codes and such easily in order to have fun colours!!
https://www.html.am/reference/html-special-characters.cfm - easy copy paste for special characters + accented letters (if you didn't know they have specific code in html! eg if i just copy an e with an accent from the web it looks like this: é )
