   1. If you open a plain HTML file, the browser will have some default styling like a bit of margin around stuff to make plain pages still be visually acceptable and readable. This can slightly vary between browsers as well. Normalize.css and others are overwriting the default styles to make it all look the same and to build your styling on top of it without interference
