Creating a border in the text box

Is there a way to draw a border around a text box? like to have the text sit within a box, it may be easier for me to divide the different parts this way? 

I'm sorry but can you please further explain what you want to achieve here. Are you still referring to the Matrix table?

Each textbox has its own border, we can apply CSS to customize it if you want. But what textbox are you referring to?

We'll wait for your reply. Thank you.
