General instructions:

1. Open the exercise in your browser and read the task and the content on the left side of the screen. 
2. You will be editing the content on the right side of the screen.
3. In order to do that, right click on the exercise page that you opened and go to ‘Inspect’.
4. Go to ‘Sources’ in the top bar and if you cannot see an empty CSS sheet where you can type the code, press Ctrl + P and start typing ‘styl’ in the search bar. Then press enter to open the CSS sheet.
5. Follow the notes on the left and start typing your CSS code to see the changes online!
6. Important! Do not refresh the page while you are editing the code, as these changes are in preview mode only and you can see them immediately, as soon as you write a line of functioning code.
7. Use the custom classes in the notes on the left side of the screen, as well as ‘Elements’ on the top bar of the ‘Inspect’ to target and style the classes and elements. For example, you can enable the small icon on the top left of the ‘Inspect’ window (‘Select an element in the page to inspect it’) to find the default class name of the element you want to edit, while you are in the ‘Elements’ tab.

Tips:

1. If the code is not showing any changes, try adding the !important tag at the end of the line before closing it (before the “;” symbol) and see if it works then.
2. Don’t forget there are usually more ways to achieve the same result. Be creative!
3. If you get stuck, write your email address in the form on the left side of the screen and you will get the solution (CSS code) in your email.
