How to let textarea appear big enough for whole content?

[pstein]

Assume in multiple textareas appear some source code text whose number of lines varies from textarea to textarea.

 

Is there a CSS style which I can attach to such a textarea and which tells the browser:

"make textarea automatically big (height) enough to show ALL lines in textarea + 1 blank line at the end but NOT bigger/heigher/more rows than necessary?

 

If this is not possible with CSS then at least is there a javascript command which let me calculate the number (and assign the "row" parameter to the textarea?

 

If lines are longer then current textarea width/columns then these lines should be wrapped.

When you say "textarea" do you mean an input textarea or do you mean a div?

[pstein]

input textarea

or as HTML:

 

<textarea ...>

...

</textarea>
