cubicweb-blog #2110315 Improve blog readability [validation pending]

As a user, I find blog entries published on the different forges tedious to read. I can think of a few reasons for that :

  • CSS could be improved : maybe a better font (larger and different family ?), more margins around images, inlined code is hard to read, ReST title levels are not always properly rendered, bullet lists rendering not that nice, etc.
  • having the default main template can be a good thing since it makes the whole site consistent, however I found it not suited to text publishing (card or blog entries), maybe because of the large white background and the different boxes around.
