Center the carousel widget

I installed the carousel widget and it works fine. The only thing I would to be changed is that the carousel is center on my form. I added 'text-align:center;' to the style of de cell and on the carousel it self. Both options didn't work. So my question: how can I center the carousel on my form?

text-align works only for text based content. For block based elements, use

margin-left: auto; margin-right: auto;
