Background Bar for Product Categories Sidebar Title

Dear Support Team,

I have an additional question regarding the same Products archive layout:

WordPress Dashboard → Layouts → Products archive layout → Edit with Elementor

I would like to add a colored background bar behind the “Product Categories” title in the left sidebar.

Please refer to the attached screenshots:

Image 1 shows the current sidebar in my template.

Image 2 shows a reference website with a green background bar behind its category title.

I would like a similar title bar, but using our website’s brand blue (#2035F2) instead of the green shown in the reference.

The background bar should span the full width of the sidebar, with white, left-aligned title text and suitable padding. The colored background should apply only to the title area, leaving the category list below unchanged.

Could you please explain how to create this effect and where to adjust the background color, text color, and padding?

This template has not yet been activated on the live website. Please keep it inactive and limit any changes to this template.

Thank you again for your assistance.

Best regards,
Jonathan
