Resize reports in html views

Resize reports in html views

If a have two or three embedded reports in a html view, is there any way to change the width, the height and the positions of each report in the html page? If yes can you please tell me an example? Because as you can see in the attached image4 the html page is not well designed. Or if there is any way to decrease the width between the roomtype and low season which is quite huge. I went to column properties of the report, I decreased the Column Width but nothing happens.
