Welcome to our daily task 
Just want to say, that you can share your code and format it adequately so everybody can see it 
Just follow: How to format code in your posts
You can try adding Keith example to your project by copying the HTML code into your code as he explained.
Then you can open the file css/style.css and paste CSS example that he shared in the same post
You can focus now, about the code, and you can preview it like he said.
If you have issues with building the app, we can see that later!
