I think I found the issue and a possible solution…if this works for you then I will make it part of the next update.
Open the theme’s style.css and go to around line 870
img {
display: block;
max-width: 100%;
width: auto;
height: auto;
vertical-align: middle;
border: 0;
-ms-interpolation-mode: bicubic;
}
Change this:
display: block;
to:
display: inline-block
Then in the style.css around line 170
#banner-wrapper {
padding: 6px 0 0;
}
Add:
text-align: center;
I just tried this with a static image but not a slider, but we will see if it works on a slider as well. If not, we’re in the right direction and I will keep at it until it does get centered.
