Client widget logos

I am looking to reduce the size of the logos that appear using the client widget.

I would like to decrease the default size, at the moment they appear on 3 lines and I would like them on 2.

Currently this is how it looks:

Hi Ozzy,

You can use this CSS code to decease the with of the client’s logo. So all logo are displayed in just 2 lines:

.roll-client .client-item {
    width: 15%;

Put the code in : Customize > Additional CSS.
