why does this end with -href again?

[Evan Stade, 2012/05/08 19:01:33]

because it's a hypertext reference?

yea, should be link I guess.

I still think we should investigate more compact ways of showing this, or hide
when the screen size is small. For example:

  #chrome-web-store-href {
    display: none;
  }

  @media screen and (min-width: 1025px) {
    #chrome-web-store-href {
      display: inline-block;
    }
  }

I personally think that's a good idea (for some value of min-width) but the
first step is to get alcor or whoever to approve that. While we're at it, we
could hide the logo as well as that's taking up as much or more space, and is
more useless.
