A few initial remarks.

The browser console shows two HTTP errors 404:

GET
https://cgal.github.io/assets/themes/cgal/bootstrap/fonts/glyphicons-halflings-regular.woff
[HTTP/2 404  11ms]

downloadable font: download failed (font-family: "Glyphicons Halflings" style:normal weight:400 stretch:100 src index:1): status=2147746065 source: https://cgal.github.io/assets/themes/cgal/bootstrap/fonts/glyphicons-halflings-regular.woff
GET
https://cgal.github.io/assets/themes/cgal/bootstrap/fonts/glyphicons-halflings-regular.ttf
[HTTP/2 404  13ms]

downloadable font: download failed (font-family: "Glyphicons Halflings" style:normal weight:400 stretch:100 src index:2): status=2147746065 source: https://cgal.github.io/assets/themes/cgal/bootstrap/fonts/glyphicons-halflings-regular.ttf 

I also see that a few older JavaScript files are found in the old Booststrap directory in assets/:

    <!-- Javascripts -->
    <script src="/cgal-web/node_modules/jquery/dist/jquery.min.js"></script>
    <script>window.jQuery || document.write('<script src="/cgal-web/node_modules/jquery/dist/jquery.min.js"><\/script>')</script>
      <script src="/cgal-web/node_modules/bootstrap/dist/js/bootstrap.min.js"></script>
      <script src="https://cgal.github.io/cgal-web/assets/themes/cgal/bootstrap/js/jquery.fitvids.js"></script>
      <script src="https://cgal.github.io/cgal-web/assets/themes/cgal/bootstrap/js/jquery.sequence-min.js"></script>
      <script src="https://cgal.github.io/cgal-web/assets/themes/cgal/bootstrap/js/jquery.bxslider.js"></script>
      <script src="https://cgal.github.io/cgal-web/assets/themes/cgal/bootstrap/js/template.js"></script>
      <script src="/cgal-web/node_modules/bootstrap-hover-dropdown/bootstrap-hover-dropdown.min.js"></script>
    </body>
</html>

That is probably a problem.

I think there is still work to do on style.css, and assets/themes/cgal/main.css. There are a lot of redundante styles. Let's do that tomorrow.

Here are a few things that need fixing:

• The portofolio on the home page is both smaller and narrower, and it has a thin white border that needs to be removed.
• There needs to be more space above "latest news / releases" (home page)
• The text of "older news / releases" needs to be reduced (home page)
• Icons associated to "cells" need to be recentered (all pages)
• The space between cells is too small, and should be constant regardless of the number of cells on the line (and should be the same vertically and horizontally)
• intermediate looks like https://www.cgal.org/April11/ are no longer accessible? (You can still access to the subpages, but the April11 (and others) will return "This page does not exist".)
• Pages are even gone? e.g. https://www.cgal.org/Events/UserWorkshop/ vs https://cgal.github.io/cgal-web/Events/UserWorkshop/
• very minor: the lock icon is ugly (use https://icons.getbootstrap.com/icons/file-lock/ ou https://icons.getbootstrap.com/icons/shield-lock-fill/?)
• add a github icon left of twitter's (or a larger with stats?)

* [x]  intermediate looks like [cgal.org/April11](https://www.cgal.org/April11/) are no longer accessible? (You can still access to the subpages, but the April11 (and others) will return "This page does not exist".)

That is a server setting. The server at https://www.cgal.org/ run Apache, and has the option DirectoryIndex. But the server at https://cgal.github.io/ does not create directory indices. Once this PR will be merged and deployed to https://www.cgal.org/, the directory indices will be back.

* [x]  Pages are even gone? e.g. [cgal.org/Events/UserWorkshop](https://www.cgal.org/Events/UserWorkshop/) vs [cgal.github.io/cgal-web/Events/UserWorkshop](https://cgal.github.io/cgal-web/Events/UserWorkshop/)

That page was supposed to be removed by 99799d1. But the way we synchronized the web site with www.cgal.org does not remove files (we use rsync without the option to remove files). The page https://www.cgal.org/Events/UserWorkshop/ should be a directory index, and not the page that is served.

Thanks @SaillantNicolas, and @MaelRL for the review and suggestions.

I have merge the PR, to avoid any more copy-pasting errors.
