Challenge Task 2/3

I have no idea why I am getting the error: Did you add you code inside the media query? I am new to this, what did I miss?

The task is to add the appropriate CSS code to the media query so that ".contact" and ".menu" fill the entire container width when the device or browser width is at most 480px wide.

 /* Mobile ----------- */
    @media screen and (max-width : 480px) {
    .contact {
      max-width: 100%;
      }
    .menu {
      max-width: 100%;
      }
    }

Hi Brenda,

Technically your code looks OK to me but I think this is what the code challenge is looking for:

    /* Mobile ----------- */
    @media screen and (max-width : 480px) {
      .contact,
      .menu {
        width: 100%;
      }
    }

And by the way, the back-ticks are above the tilde ~ key.

Hi Brenda, You are very close. I think the right code should be this:

@media screen and (max-width: 480px) {
  .contact,
  .menu {
    width: 100%; 
  }
}

Basically, you need to use the standard width property, instead of the max-width property. Please let me know if it worked.

Cheers, Carsten

Guil Hernandez - Why does is work with width but not max-width here? Does it have to with max-width not being inherited or is there something else I don't understand about max-width?
