Install command cursor highlight is the same color as the background (top of egghead.computer)

[pkrisko]

Issue

On the homepage, egghead.computer, when the text for the curl install command is selected, it does not appear like you can select the text because the background color when selecting the text is the same as the <code> element.

Suggested Fix

Change the appearance for the ::selection state, i.e.

code::selection {
  background: #ffffff;
  color: #000000;
}

or similar.

Suggested Enhancement

Add a "copy" icon which copies the install command to the clipboard.
