Input Box resize in Warp 7 theme

Good afternoon:

I am using your Uflat UddeIM template on a Joomla 3.6 website using a Warp 7 based template. Everything works except the input box when composing displays by default only one line. I am enclosing a screenshot as below:





I would like it to default to a larger size of about 200PX so it looks more like this shot:





I had the same problem with a Kunena 5 template and was given the following code to input into the custom CSS file which fixed the problem in that extension.

textarea#kbbcode-message {
resize: vertical;
min-height: 200px;
}

I assume it would likely work with the Uddeim template if I knew where I might need to input the code

If you can help at all with this it would be most appreciated! Thank you.

Well - I did some more research and fixed the problem myself

The solution is apparently to add the following to the custom.css file for the whole site:

textarea {
height: auto !important;
}

Leaving the thread in case anyone else has a similar issue.

Now it looks like this on default open:
