Remove Black Bar

Hello. Am new to Joomla and really struggling with it. I love the Hot Image Slider, and after a few bumps, I got it working. All my fault, btw...

How (in REALLY SIMPLE IDIOT_PROOF LANGUAGE) can I remove the black bar? My client doesn't like it. I searched and saw the other posts with instructions, but they were based on the assumption that the user understands the steps.

Please explain to a complete novice how to:

Find the Hot Image Slider css code so it can be modified, &
What code do I use & where does it go?

Sorry. Newbie here. You patience is appreciated! Thank you in advance.

Hi, to make it transparent:

#slide-controls{
backgorund:none!important;
}

to remove it a long with nav buttons:

#slide-controls{
display:none!important;
}

put one of this you want to bottom of template_css.css

Thank you. I will give this a try and let you know how it works for me. I have a dumb observation t make. COnsidering how many users want the black bar and numbers removed, wouldn't it make sense to give the option in the settings? Or is that already available in the Pro version?

Many, many thanks for the instructions, but especially for telling me where to insert the code. I very much appreciate your help. Issue resolved, thanks to you!
