问题
I would like to provide a horizontal scroll to a textarea in my HTML page. The scroll should appear without wrapping, if I type a long line without a line break. A few friends suggested using overflow-y CSS attribute, which did not work for me. The browsers that I use are IE 6+ and Mozilla 3+.
回答1:
To set no wrapping, you would use:
white-space: nowrap;

NOTE: However the depreciated wrap="off" seems to be the only way for legacy browser support. Though it isn't HTML 5 compliant, it's still my preference if you're targeting all browsers.

I figured out to do it in a non-W3c-compliant way and it is working in both IE and Firefox and incidentally in Chrome too.
I added the attribute wrap with value off, that is <textarea cols=80 rows=12 wrap='off'> is what I have done.

If you have pre-formatted text that includes LFs, you should add white-space: pre; to the css. That will preserve the new lines that are already in the text and will not wrap long lines.
This works in all versions of Firefox, all Webkit-based browsers, and IE6+.

Try these:
overflow: scroll;
overflow-y: scroll;
overflow-x: scroll;
overflow:-moz-scrollbars-vertical;
there should also be a -moz-scrollbars-horizontal
