Challenge: Use CSS Selectors to Style Elements

Link to the challenge:

do you have any browser extension that has access to freecodecamp?

yes I do, is that going to be a problem?

if it changes the colors of the page it can be interfering with the tests, as it may be changing what the tests are testing

Oh dam , I see. So i gotta disable extensions?

try switching them off
