I know that is not allowed to change any code of layout of adsense or adsense for search but what about effect from Css on for example input tags that can change background, font and color of button. If you place for example: input {background-color: #FFa013; color: #ffffff; font-family: Arial, Verdana, Helvetica; border-style: double; border: 0; font-size: 12px; cursor: hand} then background, font and button should change too and even cursor but original code of adsense for search as it has been given from google should stay intouch.Thus not any modification inside original code. So my question is of this is allowed or not?
