Hi Ann,
Thank you for taking my request.
Do you mean like <div class="wrap my-theme-settings">
this?
Ah, yes it can work but if you can add a inner div, it will be more convenient to style it more better. like <div class="wrap"><div id="my-theme-settings">
But both methods are ok for me, whichever you think possible to add.
Best Regards,
Aishwarya
