Challenge: Learn Responsive Web Design by Building a Piano - Step 27

Link to the challenge:

See example in this link to write media quwery ( for this challenge you may remove the words only screen and )

I don’t realy understand a media query does or how it works so i dont really understand what that’s showing me.

The @media rule is used in media queries to apply different styles for different media types/devices.
For example the layout of FreeCodeCamp that we see in laptop is different when we see from mobile phone that because @media detect the size of the screen is different and adjust what should display depending on the size of the screen.

in the w3school above give some example, try click Try it Yourself it is really helpfull to get some idea about media query
for example: Tryit Editor v3.7
try make your browser smaller and the yellow part will be hidden.

Hope this will help.
Don’t worry if you feel frustate for now, take a break after that slowly read the explanation, the examples and click Try it Yourself

If you don’t understand what something is or what it does, look it up online; otherwise you’ll have a knowledge gap. There are many great resources. CSS-Tricks is one of them:
