Slider text box background colour

Hi again, I'm wondering if it's possible to change the colour of the text box for the slider text and buttons - so it matches the theme colour, rather than being black.

 

1.For your first issue

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.flex-caption {
background: red;
}

2.For your second issue

It is not possible to change button color because it is a image not a color , If you want to change it color than, Go to images directory present in your theme directory and replace your image with present pagination image or edit it.

The name of image is "pagination.png"

Note:- Use same name for your edited image and remove the current image.

 

Thank you - much appreciated.
