Various Types of News Feed Layouts:
- List All Newsfeed Categories
- List Newsfeed Category
- Single Newsfeed
- Joomla Announcements (Feed Gator)
Styling Newsfeeds can be a real nightmare, not because of CSS difficulties, but because each newsfeed content provider has different ideas about how feeds are styled when delivered (the FeedBurner ones like Joomla uses are infamous and limit possible CSS styling). So in practice you need to style each feed as it comes, in as far as possible (as some feeds offer very limited styling possibilities). The styling in this template attempts to counter most bad practices.
If you want to incorporate external feeds into you site seamlessly, then use a component like Feed Gator, which actually import RSS feeds into your site database first, after which they become normal content (inside a category) and will then have the exact site styling from the template.
FeedGator for Joomla 3.x is still in beta (2015-05).
