Hiya Ava Jones! :wave:

Everything looks create in the code snippets that you shared! As this is a large challenge with many partial files, can you please share your project as a whole? Either with a workspaces snapshot or a github repo.

Also, if you download the project files from the course and then run the completed challenge in the S6V3_Challenge_Complete, are you seeing the same issue with the overlapping?

Thank you for your help but this course doesn't have a workspace right now and i don't currently have a github. I also don't really know what the file you are referring too. And i cant use a screenshot on treehouse it doesn't seem like.

I get this error when i run the program by pressing the start button: avajones@Avas-MBP flashcards % nodemon app.js [nodemon] 3.1.0 [nodemon] to restart at any time, enter rs [nodemon] watching path(s): .

Hello again, Ava Jones :wave:

Unfortunately, that error does not provide details that would aid in troubleshooting your issue. The files I am referring to are the Project Files. You can use this link or click on downloads under the video. As a reminder, it will be the S6V3_Challenge_Complete folder that you will want to check out.

Another option for sharing your project files is to join the Treehouse Discord Community. This platform allows you to send a zip file of your project and screenshots, making it easier for us to assist you.

Brian Jensen, I believe I've identified the issue. The style.css file contains over nine errors.
