How to align the text in the HTML block

Hello,

I wonder how I can align text and advertising google  in the text editor in the HTML block

I tried to put the tags <center></center> or <div align="center"></div>

but it is automatically deleted

Do you have a solution?

What version Dolphin are you using?

this works

<p align="center">YOUR ADD CODE</p>

Thank you,
But I did it in the template
like this:

dbContentHtml {

text-align:center;

}
