Allow all html elements to be styled from JavaScript #109

Currently the only practical way to style some of the div elements is with css, e.g.,

/* override default rc-collapse-content */
div.rc-collapse-content {
padding: 0 5px;
}

/* override default rc-collapse-content-box */
div.rc-collapse-content > div.rc-collapse-content-box {
margin-top: 5px;
margin-bottom: 5px;
}

Please provide a way to override these styles from JavaScript. This will allow these elements to be styled using Glamorous or Glamor or Emotion, etc.
