HTML Editor Extender Customize Toolbar Styles

I'm trying to customize the Toolbar
- Have 2 toolbars showing at the top not just autowrap the 1 toolbar. 
- Increase Padding around the buttons. 
- If possible make the buttons bigger.  (They are so tiny I work with OLD people who have trouble seeing!)

The HTML Editor is defined as this:
<ajaxToolkit:HtmlEditorExtender ID="htmlEditorExtender1" TargetControlID="meetingNotesTxt"  runat="server" EnableSanitization="false" >   

I found this and it does change the background color and padding in the text area:
 .ajax__html_editor_extender_texteditor{ background-color:#FFA500; padding: 20px 20px 20px 20px; }

I tried this but it didn't work  from here: http://ajaxtoolkit.net/HTMLEditor/HTMLEditor.aspx
 .ajax_html_editor_extender_toptoolbar{ background-color:#FFA500;padding: 20px 20px20px20px; }

Doesn't work.  Anybody know the css change for the toolbar?
