I am using Xara Web Designer Premium 365. My client wants a dark box somewhere on the page for some scrollable text. The text is to scroll only within that box area. I watched an Xara YouTube training viedo that instructed using this HTML code placed in the body.

<textarea readonly rows="25" cols="50">

what ever text I choose to place here

</textarea>

It works, however, I now have a dark box (which I need) with a white box inside where the text is (which I do not need) and then the black colored wording. What I need is to be able to have the text area be transparent and I would like control over the color of the text so that I end up with only the dark box on the page with the white text scrolling within. Is there a different code I can use or can this code be edited?
