Hmmmm three little symbols

Its amazing what 3 little icons can do. I was told that having these 3 symbols at the end of a paragraph will give me them when by blog posts.

However does this now mean i have to do it at the end of every place i want a paragraph?

Surely not, that is going to be really tiresome!

Have i accidentely mad changes to my html without realising it?? What a pain this will be!
