Organize CSS and Javascript files into directories, separating vendor
source code from home-grown.
Separate new properties and selectors in Bootstrap CSS (already edited
for Hugo) from:
1. Original property values; and
2. Changed property values.
For the home page:
1. Clarify the English text;
2. Add some element names to classes in CSS selectors (to speed loading);
3. Document the Owl Carousel and Highlight.js versions;
4. Add Owl Carousel's license;
5. Restore HTML comments to browser source views;
6. Make the beginning GitHub button transparent on focus (like the others);
7. For the final, colored Twitter and Github buttons:
a. Remove the dotted box on focus; and
b. Color them green on active.
8. To increase (layout/) source readability:
a. Place `class` attributes before `href` attributes;
b. In `class` attributes, place more-specific class names before
less-specific; and
c. Comment the beginnings and ends of Bootstrap rows.
9. To increase understandability during development:
a. Document the meaning of CSS file, `HPstyles` by renaming it to
`home-page-style`;
b. Move inline styling to CSS stylesheets;
c. Separate @media queries to a file;
d. Separate the inline Owl Carousel custom Javascript to a file;
e. Use regular Owl Carousel CSS files instead of minified ones; and
f. Rename the wide, landscape desk background image filename from
`desk-long` to `desk-wide`.
The GitHub:buttons JavaScript code docs/static/js/buttons.js
from https://github.com/ntkme/github-buttons was referenced
in docs/layouts/partials/footer.html but never used.
Apparently, the actual code for the GitHub buttons on the upper-left
corner of gohugo.io documentation was written by @spf13 in
docs/static/js/scripts.js.
* Add meta author, description and generator tags
* Add Hugo version beside the logo and in the footer
* Suggest the user to run `go get -u -v` to update dependencies
* Requires Go 1.3+ rather than Go 1.1+
* Improve rendering/formatting in some places
* Add trailing slash to URLs where appropriate
