it is the page about the role of meta description.
with the following link :https://www.freecodecamp.org/learn/responsive-web-design-v9/lecture-understanding-how-html-affects-seo/what-is-the-role-of-the-meta-description
it gets stuck on the loading page. The other pages do work tho.
Please try one of the following steps to move forward.
or - Try to enter the page in incognito or private mode.
or - Disable any/all extensions that interface with the freeCodeCamp website (such as Dark Mode, Ad Blockers, or Spellcheckers).
or - Ensure your browser is up-to-date or try a different browser.
I hope one of these will work for you.
