How to add a section of a website into view controller?

I am trying to add a section of a website into a view controller in Xcode. I need the section in the app to perform the same way as it does on the website. The website I'm trying to use is https://davidmathlogic.com/colorblind/#%23FBC531-%23192A56 and I simply want to use the color palette section. The author of the website has granted me permission so that is not an issue.
