When you write blog posts, they get listed all together on one page, but they are all truncated (abbreviated) so that users only see the beginning of each post. Because they have been shortened, we cannot leave any HTML formatting.
However, we have created a widget that allows you to list all the entire posts in full HTML. It is called [CONTENT:BLOG_FULL]. You can insert this tag anywhere in your website and it will list all blog posts in HTML.
