Three columns layout issue in responsive mode

Hi,

I have a three column layout.
It looks fine in Thunderbird and Outlook from PC.
From the mobile phone it is not seen correctly.
Is there a way to not render the layout content vertically?
And if there is no way, how to center the columns?

Another thing:
Spanish is the language of the web.
when an accent is placed on a capital letter in a text field, the template does not save the changes. It is not a big problem, it is only for your knowledge.
Example:
When you write a word that contains á, é, í, ó, ú, there is no problem.
When you type Á, É, Í, Ó, Ú, it does not save the changes made to the template.

Sorry for my English. I don’t speak it.

Thanks in advance.
