How to change style of the slider arrows

Hi there,

Do you have a link to your site?

Have you considered Meta Slider Pro which features a Theme Editor that makes this type of customisation straight forward, without the need for code changes?

Dear Dave,

I actually have.

Here is the link to my website.

Also, is there a way I can actively modify my images without them being cropped, so they originally fit the 960×400 slider?

Best wishes
