I really do not understand what you mean by wrapping your contents. Do you mean like having borders around your contents?

I see you are using the latest default theme and to have borders around your contents go to your style css, scroll down until you come to the part commented with the words, “Contents”

Find these codes:

#content,
#content input,
#content textarea {
color: #333;
font-size: 16px;
line-height: 24px;
}


Immediately after the last line just before the closing curly bracket, add this line.

border: 2px solid #ddd; padding: 15px;


This will create a border around your contents. (If that is what you meant by wrapping your contents) Otherwise, I really do not know what you want.
