Here is my original request (not very well written) to ChatGPT.
retrieve data from this api https://developer.nps.gov/api/v1/parks?stateCode=co&api_key=jHiO1R5Cxohjya05TtDkkoNDf40W3c5NmHuFlDpd and display on html page And use fetch api add image urls to external variable named pd
Here is a link to the result and to a more complex html/js file that built on the result.
Here is yet another link to an html file based on the Prologue theme from HTML5up.net that takes things even further. Data is retrieved, but this time is injected into a pre-existing theme to create a halfway decent webpage with lots of information about National Parks in Colorado.
