/* ==========================================================================
   Slider and Carousel tags (mgtags/mgcarousel.cfm) - the content listings'
   strip, drawn for images.  Linked by the tag itself rather than built into
   the site's stylesheet, so a slider draws correctly before a rebuild.  The
   script is the listings' own (includes/js/common.js initStrip).

   Themes style their header banner through FlexSlider's class names, which
   the markup keeps (.flexslider, ul li, .slide_text, .slide_title), so the
   rules here are kept low enough for those to win.
