APEX

I cannot seem to find a way to change the height of a textarea which is inside a report row.

Currently i have tried following:

1 change column attributes -> element attributes to different kind of css values for setting height
2 added the css in the column formating -> css style
3 added a css class in the page html header and the setting the column formating -> css class to this css class.

Non of those seem to make any changes to the textarea.

more specific data (

at point 1 and 2 i tried those values: ( height:20px and max-height:20px )
at point 3 i added this to the html header:
<style type="text/css">
.textarea
{
width:30px;
height:20px;
}

and then at the column formatting -> css class i added (.textarea and also tried textarea without the dot)

So hope someone can give the guidelines to solve this succesfully

TIA
