Hello Abhishek
Thank you for reaching out to the Brightspace Community.
Based on your description, I understand that you are trying to upload a CSS template into brightspace and have and option to use the same template at every HTML editor.
Unfortunately, this option is currently not available. You will have to upload/paste the CSS code required into the HTML editor [ Source code editor] individually.
If you would like more options I would highly suggest the submission of a PIE item, or upvoting one that suits your use case. You can also create a new PIE item and upvote.
