Create Bottom Border On Easy Slider

Hi Guys, i’ve added some css that makes all my borders black and 3px, but i want a 3px black border at the bottom of the full width easy slider but just can’t figure it out, if you look at the homepage, at the bottom of the full width easy slider there is no 3px black border, this is where i want to add one, but not sure if any of the below css i have added so far is causing an issue, thanks in advance guys… :-)
