Can we redesign the layout

The layout of the form is always on the center in 1074 resolution... when I embed it on my website... which is on the center... the 0 x-axis of the CRM form is the X-location where i put it.. i wanted that the form should adopt if it was put on the table... it will always remain center... and secondly the buttons can we change the Save into Send... or submit...
