Hello, i have just returned to freecodecamp after a while

\The new updated site is confusing me a little, more exactly, i am going through the HTML and CSS challenges and when i am complete and want to click run tests, nothing happens. Could someone explain to me how this new website works. Thanks

Can you provide a link to the challenge that you are running the test on, and also which browser you are using?

try using firefox or chrome to view the site, Internet Explorer doesn’t work.

Im using edge, think that’s the problem. Thanks.
