Gallery block formatting banner descriptions

Hi, I am using gallery block as banner slideshow but unfortunately the text stays in the center.  I would like to have the text description box be on the right side of image instead. Anyone know how to do that?

It seems you solved?

Thanks for your reply. Sorry for the delay I didn't have notifications set up. It is sort of fixed. But now I would like the text to fit more in an area like this blue rectangle. Is there a way to do that?  

Try adding to Home > Design > Custom CSS

.meta {
    right: 0 !important;
    left: unset !important;
    max-width: 100% !important;
}
