Need higher field for MESSAGE in the contact form

Hi,
I think you can add css into your template
textarea{
height:200px !important;
}

The problem will be solved.
Thanks

Do i need to add / modify 'heigh : 200px ' to one of that css file that I find in the code source of my contact page?
or this form is available in another location?
I already make few test and i wasn't able to localize the right location of the field Message

Here are the CSS file charged in contact.php :

Hi,
You can modify it in file: components > com_osproperty > style > frontend_style.css
Thanks
