+Don't combine element types with classes and ids. Preferably don't style on elements at all. Reasonable exceptions are in a base reset or when styling elements that can not be targeted in another way (e.g. elements that are generated from a wysiwyg editor or coming from external sources).

 /* Recommended */
 .overview {}
 
+/* Encouraged exceptions */
+.wysiwyg {
+ h1,
+ h2,
+ h3 {
+ text-transform: uppercase;
