I attempted to replicate this html/css snippet from the following link:
I copied all of the html code and also included all the css, including any linked style sheets, into a single document.
Upon running the copied code in the browser, it displayed correctly but none of the elements were responsive to interaction such as clicks.
For instance, when I clicked on the "Dropdown" button in my copied version, no action occurred.
How can I ensure that I copy this snippet correctly so that it functions properly?
Despite consolidating all available css into one document as an attempt, the issue persists.
