First project with HTML and CSS QR Component

To get background images to show, you need to put ' ' in the parenthesis like this: background-image:url('./images/background-image');

also, why do you have 3 index.html files? You should only have one. I also believe your css file isn't linked properly in your html file. I use this: <link rel="stylesheet" href="css/normalize.css"> <link rel="stylesheet" href="css/main.css">

and refer to the style guide for font-weight. With this one, you should use 400 and 700 for normal and bold. So it should look like this: font-weight: 400;

Here is a good source for media queries from DEV.to, it's very helpful. In the style guide, they give you the 2 you'd need, mobile and desktop. You can choose to do tablet if you want to get more practice.

Hope this helps and good luck!
