I hope you are well today and thank you for your question.
You can achieve this developing custom CSS code as shared in the below topic.
You can try achieving this using Yellow Pencil editor as described in the below page.
If you can’t do it using Yellow pencil editor plugin then to achieve this, you have to develop custom code in the child theme of Jevelin theme.
Developing custom code for custom functionality is beyond the scope of support that we provide here. Please see https://themeforest.net/item/jevelin-multipurpose-premium-responsive-wordpress-theme/14728833/support
