/* increasing and decreasing text size.
how this works:
1- loop through all of the stylesheets
2 - check if they have a title
3 - check if that title contains "article" (indicates our article stylesheet)
4 - disable all article stylesheets
5 - enable the next size up or down.
6 - exit, enjoy the day.
