This is kind of hard to explain, but here is my problem:
When, at least on my laptop, you scroll upwards with the touch-pad, the cursor won’t move. If you scroll sideways, the cursor moves sideways. I’d rather the cursor doesn’t move at all. Is this possible? Can you cancel side-ways scrolling? Can you enable upwards scrolling?
Thanks, hopefully that is comprehensible.
If I understand correctly your problem, you want to control the scroll of your textarea! So, in order to control the scroll of a textarea, you can use CSS just like you use it to any other element that as scrolling capabilities:
No scroll
No vertical scroll
No horizontal scroll
Additionally, you can disable the text wrapping, thus forcing an horizontal scroll bar (non-W3c-compliant).
Textarea tag to disable wrap
Note: Just tested this on your Fiddle.
