We run a social networks based news service, were people can post and reply to the News.

The replies section is formed by <div class=""> type formatting.

The replies sections look completely fine under ALL web browsers but IE.

Anyway, can you please suggest what changes we need to make to the CSS for the replies sections to also look fine under IE. You can see a sample news articles with replies here:
