Thank you, but while the text-align command appears in the css, it takes still no effect in the news source. Text-decoration, however, is still working fine.
Edit: With an exclamation mark before the "important", it works all!
Thus:
Code:
extra_css = 'td.textb {font-size: medium;} * { text-align: justify !important; text-decoration: none !important}'
Thanks everyone!
