[Gnuastro home page] Proposed changes

[Thérèse Godefroy]

Hello,

The Gnuastro home page contains a few HTML tags and attributes that
don't fit with its HTML5 header. I propose to replace them with valid
markup and do some other minor changes:


*English version*

* <style>: use existing classes (see https://gnu.org/layout.css) to
simplify definitions.

* Introduction: place it on top, without heading, for better visibility
on smartphones.

* Download: emphasize the latest release and the note about new releases.

* Repology table: remove align="right" ('pict' class does the job).

* Documentation: keep the commands from wrapping; use <kbd> instead of
<code> (light gray background); <var> for placeholders (italics).

* Test releases: reword to avoid displaying clusters of long URLs
(difficult to read, especially with accessibility tools).

* Recent citations of Gnuastro: replace <font size=2> with <small> (same
rendering with Firefox).

* Footer:  delete an irrelevant comment about translations (software
pages are usually not translated by the gnu.org teams).

* Boilerplate edits:
  http > https where possible,
  local URLs relative to server root,
  update to version 1.95.


*French translation*

* Same changes as in the English version.

* Replace <cite> with <i> for English words.

* Minor edits.

* Review the comment about GSoC: it may be useful in the future.

* In the footer, delete an irrelevant paragraph about translation.


A diff is attached. If you agree with the changes, but don't have time
to commit them, I will gladly do it.

Best regards,
Thérèse
