I had the same idea, but the thing is: There is no extra_css in the recipe included in Calibre (yielding a grey background):
Spoiler:
__license__ = 'GPL v3'
__copyright__ = '2010, Alexander Schremmer <alex@alexanderweb.de>'
from calibre.web.feeds.news import BasicNewsRecipe
class TazRSSRecipe(BasicNewsRecipe):
title = u'Taz.de (die tageszeitung) RSS Feed - German'
__author__ = 'Alexander Schremmer'
language = 'de'
lang = 'de-DE'
oldest_article = 7
max_articles_per_feed = 100
publisher = 'taz Entwicklungs GmbH & Co. Medien KG'
conversion_options = {'publisher': publisher,
'language': lang,
}
feeds = [(u'TAZ main feed', u'http://www.taz.de/rss.xml')]
keep_only_tags = [dict(name='div', attrs={'class': 'sect sect_article'})]
remove_tags_after = dict(name='div', attrs={'class': 'rack'})
remove_tags = [
dict(name=['div'], attrs={'class': 'artikelwerbung'}),
dict(name=['ul'], attrs={'class': 'toolbar'}),]
…and there is no “no_stylesheets = True” in my very basic recipe (yielding a white background):
…and the articles on the Taz website viewed in a normal browser don’t have a grey background at all.
In addition, when I add “no_stylesheets = True” in the recipe included in Calibre, the background in the articles is still grey. So there must be something going wrong with the some of the instructions. Very strange!
