Hello @imincognito ,
Thanks for reaching out to us. I’m very sorry for the delay in getting back to you.
Please find the answer to both of your queries below-
1) ElementsKit Plugin does use the jQuery library, which is available for WordPress.
2) The Elementor Container support is included already with the ElementsKit. You can use the Elements of ElementsKit plugin with the Elementor Container. I hope you’ll not face any issues.
Let me know if there is anything else that you need help with.
Best Regards,
Prosenjit
