How to build a responsive Bootstrap layout with custom hamburger breakpoint, cards, and a gallery modal?

I am trying to build a responsive webpage using Bootstrap (v5), but I am struggling to combine several layout components effectively into a clean structure.

Here are the specific layout requirements I am trying to achieve:

Navigation: A navbar with a hamburger menu. I need to customize the breakpoint/max-width so the hamburger menu appears at a specific screen size (e.g., [X]px), and I need to position the nav items specifically (e.g., aligned to the right).

Hero/Background: A main section with a responsive background image.

Grid & Cards: A responsive column system (for example, a 2-4-4 column layout) where I display data inside Bootstrap Cards.

Links: Anchor links that jump to specific values or sections on the page.

Image Gallery: A gallery of small thumbnail images. When a thumbnail is clicked, it should open the full-size image (presumably using a Bootstrap Modal or a lightbox approach).

What I've tried / What I need help with: I know I should use the navbar, card, col-*, and modal components, but I'm having trouble getting the custom breakpoint for the navbar and the thumbnail-to-modal gallery working together smoothly in the grid.

Could someone provide a skeleton layout or guidance on the best Bootstrap classes to achieve this combination?
