I am trying to make the shape below in CSS. Any ideas how to do this? Or know a tutorial site that can help? I am talking about the tag like shapes that are yellow.

Also secondly does anyone know how to make a shape with css that is a square/rectangle that has two rounded edges at the bottom but right angled corners at the top?
Thanks!
