execCommand: how to use CSS in IE to set text-align option?

Question

css

Hello. I'm trying to create my own wysiwyg editor, but I need to make sure that the code is the same in all browsers (why? below). When setting text centering in all browsers except IE, it happens like this:
<div style="text-align:center;"></div>
In IE, for some reason, html parameters are used and it turns out like this:
<div align="center"></div>
I tried to set styleWithCSS, it didn’t work, maybe I didn’t use
it
correctly
The code must be the same so that if the same code is opened in another browser, the parameters will not be generated.

Answer 1

<div align="center" style="text-align:center;"></div>

If via CSS:

.yourClass
{
    text-align: center;
    align: center;
}

Answer 2

Do you mean assign a class?
It is required to make the command
set the parameter via CSS

Answer 3

yourelement.style.textCss = "text-align: center";
