If you minimize the browser window, the tab is supposed to change to a drop-down menu, but the button does not work at all. I have checked the individual pages and they seem to work just fine, just not when they are combined.
Am I doing something wrong? Could someone help? All the code I used is from w3school and I have only modified the file names (tab.html and content .html to point to the right files). Below are links to the code:

Code for ‘content.html’ - https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_collapsible_symbol
Code for ‘index.html’ - https://www.w3schools.com/howto/tryit.asp?filename=tryhow_html_include_2
