Certification Project Bug - HTML/CSS disappears

Hello! I have worked through the HTML and CSS courses and have made it through to the JS section and both times when I get to a certain point (amount of code maybe?), all of the HTML and CSS disappears off the preview screen and I can’t figure out how to get it back.
When I run the tests it says that some of the user stories (which I previously passed), now fail. All of my code is still in the IDE, but just the preview doesn’t show. Previously, I also tried cutting the code from the IDE and pasting it back in and this will work until I update the Javascript or open the instructions tab.

I’m wondering if this is happening to anyone else and if there is a way to fix it? I have just been adding it to VSCode so I can continue my project but I would like to be able to finish it in fCC :frowning:

Thanks in advance

Hi @tehminahopgood

Reset the step and try again. If that doesn’t work, refresh the page, disable dark mode, disable ad blockers. Or, use another browser.
If the above steps do not work, you may need to restart the computer.

Happy coding

Hi! I just tried those methods and still the same problem. It has only happened on the Palindrome checker and Roman Numeral checker- I turn my computer off between uses and when I come back it’s still the same problem :pensive:

The Palindrome Checker project displays the HTML correctly on my computer.

Can you try incognito mode on each of your browsers?

I just got it working for the moment by completing my if…else statement, so maybe that was the issue! I didn’t realise it effected the rest of the code so much, Thank you for your help!
