Centering a widget in a text box-Help needed!

[HTML, CSS and Design Help]

Hi all,
I'm trying to set a widget in the middle column of my page, but after placing the code in the text box and saving, this widget shows up to the left of the column, not in the center of the space.
Could somebody please help me with this issue?
Some additional code to throw along with the widget code?

As it appears in my page:

In red, widget placement as I wish:

Thanks a lot,

Hi,

If you apply the property "margin:0px auto;" to your div, this should center it in relationship to the textbox.

Cheers!

Thank you Derrick,
But I forgot to mention that I have little knowledge of code.
I have tried including that line in different ways in the widget code to no avail.
Mainly because I don't know what I'm doing. Even though no matter how or where I set that little piece of code, it will get change automatically. (When I re-open the Text Box to "Edit" , the code appears in a different way)
I will understand if you don't respond to this, but could you tell me how to set that instruction in the full context of the widget code.
There is attached a file with it in case that you decide to help me again.
Thank you very much,
Jose
