I have an announcement list App, but when I click on an announcement item, the detail view will show the announcement item inside a small part of the page. And the text will be vertically organized , while the horizontal area will be not consumed .
So my question is how I can expand the announcement list fields including (title, body, date, etc) to expand horizontally . I have shown the item and the associated css using F12 developer tool inside IE:-
Thanks in advance for any help.
