Learn Responsive Web Design by Building a Piano - Step 28

HTML-CSS
1

Tell us what’s happening:

I figured out how to use proper syntax for the @media query (it is correct in my code), but I STILL have no idea where to get the ‘max-width’ value. I had to figure it out by looking at others’ code and their max-width, but I want to know where that value comes from for later.

Where does the max-width value come from? I can’t find it in any of my source code. Is it a read of my browsers current max-width? How would I know what that is?

Many thanks–

Hello, the selector is wrong it comes from .keys not #piano also the width is incorrect.
I ran this code from the console output and it passed but from the other post here you need to add another selector.

3

After that add add a .keys selector and set the width to 318px. Same as you added that selector for #piano

While my code is on Step 29, I am asking about Step 28. I have already solved Step 28.

I want to know where the ‘max-width’ value in my media query comes from, as explained above.

Thank you for hanging with me–

5

Max- width is not a value it is a property.

6

I could not find in any instruction where to get the value for the property of max-width. It was not given in the Step 28 instruction.

7

Ok, but that was from step 27.
