Fixed right and width css problem

Hello, I want to use your widget with the floating right top position, the problem is that in that position I also have a menu button (it appears when the web page became small), so I would need to change the css right and width properties so I leave space for that button (right 30px, width 225px).

<div class="sfsiplus_norm_row sfsi_plus_wDiv" id="sfsi_plus_floater" style="z-index: 9999;width:225px;text-align:left;position:absolute;position:absolute;right:30px;top:35px;" data-top="1350">

Any idea how can I manage to change them?
Thank you
