Quote module line items width

Hi,
I apologize in advance if I bring up this discussion from some time ago.

Basically, any setting of yui-ac-content doesn’t work because right above it is yui-ac-container at 45%. See Attachment.

This class is always inside the yui.scss file but there is no way to see the changes. “!important”, Repair and rebuild, clear cache don’t work.

Has anyone had any luck on this topic?
