How do i change the width of the quick comments section

[enigma5]

I need to change the width of the quick comments section for it to fot my site corectly. I tried editing quickcom.tmpl but that really didnt help. Is there something that I am missing? Or do I need to edit another file?

It is indeed that file quickcom.tmpl for regular photopost

<textarea name="message" cols="80" rows="5"></textarea>

and vb3enhanced it follows your form width but you can change it

<textarea name="message" id="qr_message" class="bginput" style="width:{$vbphrase[form_width]}; height:100px" cols="60" rows="5" tabindex="1"></textarea>
