Design a Blog Post Card - Design a Blog Post Card

Tell us what’s happening:

I try to run test but this error happen everytime.
9. Your .blog-post-card element should have a white background.
So I go to CSS and try change backgroun-color and it’s work.
Then I go back change it to white and error happen again? idk why this happen?

Your solution works from my end. Please try one of the following steps to move forward.

Click on the “Restart Step” button and force a refresh of your page with CTRL + F5 then try to paste the code in again.

or - Try the step in incognito or private mode.

or - Disable any/all extensions that interface with the freeCodeCamp website (such as Dark Mode, Ad Blockers, or Spellcheckers), and set your browser zoom level to 100%. Both of these factors can cause tests to fail erroneously.

or - Ensure your browser is up-to-date or try a different browser.

I hope one of these will work for you.

Thank you after 1 day go back and try to run again it pass.
