bug#47671: Small tweaks & fixes for Emacs/GNU ELPA websites

[Sebastian Urban <mrsebastianurban@gmail.com>]

Hello!

First, GNU ELPA website. According to the LAYOUT.CSS
(http://git.savannah.gnu.org/cgit/emacs/elpa.git/plain/html/layout.css):

body {
   font-family: "fira sans", sans;
   (...)
}

pre {
   font-family: "Fira Mono";
   (...)
}

Website should set Fira fonts, but if external fonts are not allowed,
it loads the default font (usually a serif font, e.g. Times New Roman
on Windows) for everything, because for example Firefox expects
"sans-serif" instead "sans", while "pre" section is missing
"monospace". Additionally, ".tt, code" don't have defined fonts, hence
on the main page "Fira Sans" is used (for keys and commands) instead of
monospace font.

Second, "A Guided Tour of Emacs" website. According to the LAYOUT.CSS
(https://www.gnu.org/software/emacs/layout.css):

pre {
   font-family: monospace;
   (...)
   font-size: 1.2em;
}

This is used in the "Download" section, actually. It's missing "Fira
Mono", and I don't think font-size is needed there at all.

body {
   font-family: "fira sans", sans;
   (...)
}

Basically the same problem, as above (1st point).

tt, code, kbd {
   background: #efeadc;
   border: 1px solid #ccc;
   padding: 2px 6px 0px;
   border-radius: 4px;
   /* color: #ddd; */
}

No font-family defined, commands are printed with "Fira Sans"/"the
default font" depending on the permission.

Finally, there is an "inline" style for "kbd" inside INDEX.HTML
(view-source:https://www.gnu.org/software/emacs/tour/index.html):

kbd {
   font-size: larger;
   background: #ffe;
}

It makes "kbd" elements, well, larger. I just think it looks better
without it, but this is just my opinion.



Third, there are leftovers after bug#43000:

Unfortunately, due to background colour for the "Releases" section,
visibility is rather bad. Possible solutions:
A. Remove background colour from ".releases" (this one: "background:
#F0EBDE;") AND set inline style for "kbd" like in the Emacs Tour (this
also means more consistency for "kbd"), i.e.:

kbd {
   background: #ffe;
}

B. Only set inline style for "kbd" as above.

Here, for consistency with the Emacs Tour, inline "kbd" could be added
as well.
