Decide Between ngIf and ngShow / ngHide

When I first started using AngularJs I used ngShow and ngHide a lot and never even consider ngIf. When someone explained the power of the latter to me it completely changed the way I thought about programatically showing and hiding content with AngularJs. There are plenty of reasons why you would want to hide and show content, and it's worth considering which option is best for you each time you need to do so. A large part of your decision is going to be to do with whether or not you are using psuedo-classes to style the element and it's siblings.
