low opacity of background of caption on slideshow

Hi,
I need help to reduce the opacity of the background color behind the caption text in the slide show.
Please see the site here, http://192.185.154.195/~global/

Thank you!
Kind regards,
Saeed

Do you mean images with kids added to Image Show module?

Thank you for your prompt reply!
The background black color of the caption text in the slideshow as shown in the attached screen shot.
Kind regards

Here is the code I have used to reduce the opacity of the background image of the caption text but it did not work:

Code: Select all

.gkIsWrapper-gk_storebox figcaption {
  opacity: 0.5;
  filter: alpha(opacity=50); /* For IE8 and earlier */
}

or

Code: Select all

.gkIsWrapper-gk_storebox figcaption img {
  opacity: 0.5;
  filter: alpha(opacity=50); /* For IE8 and earlier */
}

Do you have any other suggestions?
Thank you!

I have figured out the solution:

Code: Select all

.gkIsWrapper-gk_storebox figcaption {
  background: rgba(0, 0, 0, 0.4);
  filter: alpha(opacity=40); /* For IE8 and earlier */
}

I'm glad you were able to solve it by yourself.

Ps. Thanks for posting the solution.
Have added it to override.css instead of editing template core css files?
