How to Update (Margin/Padding) inside Align-Left, Align-Right, and Align-Center for Images Inside WYSIWYG

Hello,
To remove the padding around any any images inside a text field:

img.align-left { padding: 0!important;} 
img.align-right { padding: 0!important;}

Best wishes,
Alaa

Thank you. I tried, but maybe I had written something wrong.

Thanks again and best regards
