add style="border:1px double turquoise; border-radius: 5px;" to the template, inside the opening tag for the element. This may be better done using raw code on the profile page rather than a template so that you have less templates on the wiki (that feature is meant to be kinda for bits and bobs that go on lots of article pages). You may also want to get any visual code you need by searching 'code description w3schools' into Google which will get you onto a page from the W3Schools site decribing the CSS property and how to use it. (I think they do seven languages, I literally coded the design of my whole wiki with its help.)
