===========
Your issue is most likely regarding specificity. Chris Coyier has a great article on [CSS specificity](http://css-tricks.com/specifics-on-css-specificity/). I would also suggest you check out this handy [specificity calculator](http://specificity.keegan.st/).
Using that calculator, we can see ... | You can add `!important` after each style in the `.red` class. Adding !important basically will give the CSS more weight which allows you to override other styles.

}
