I have the following:
Item 2
In webkit I can easily style this with css. Firefox is ignorin
When overriding styles for a contentEditable panel, the css selector I found that firefox was adding a css-selectable "focus-ring" to my root contentEditable node
:-moz-focusring:not(input):not(button):not(select):not(textarea):not(iframe):not(frame):not(body):not(html) { outline: 1px dotted;}
Try variants of:
-moz-focusring or -moz-focusring[contentEditable='true']
You may want the aforementioned styles:
background: rgba(0,0,0,0);
resize:none;
But, you may need to firebug lookup the -moz specific resize parameter to disable.
For cross-browser stylesheet tests, just browse to this test data url:
