Hello
I translated the steroid language file into Farsi and I want this page to be displayed from right to left like the attached image.

I just need to add RTL direction to astroid settings page but I can't find it.

 

I find the CSS file in this path:
public_html/media/astroid/assets/vendor/manager/dist
and add direction RTL code but it still not working
any idea?

First of all, I don't understand what exactly you want to do. Please explain in more detail. If you want to change CSS codes, this is always done in the custom.css and not in the original files, as these are always overwritten during updates. Now please explain exactly what problem you have and what you want to achieve. Nothing can be seen in your screenshot. Also provide the necessary information about your versions of Joomla, Astroid and template.

What is RTL???
