4. Switch the order of the rules you created and use the dev tools of your browser to understand how specifity resolves conflicts (for the elements).
5. Set a default font (e.g. sans-serif) for the entire content of your page and use "Inheritance" to change the font of the items, too.
6. Use a combinator to give all elements but the first one (!) a black background and white text color (don't worry if the numbers disappear).
7. Use another combinator to now give all inside an element a black background and white text color.
