This has happened in more than just CSS and even within the same exercise. For example, this practice has me change the font size of the paragraph labeled p to 18px. I then add “font-size: 18px;” within the curly-brackets and it says that it is wrong, afterwards I will ask for solution and nothing would have changed and the code added will be exactly the same as what I had. What is going on and am I doing something wrong?
Furthermore, while I play around with css and run the command that it asks nothing changes on the front-end website model, is that normal or is something going on?
