Squarespace Responsive Design Tweaks

My Squarespace site looks fine on desktop, but certain sections misalign or overflow on tablets and phones. I need an experienced Squarespace designer — comfortable working directly inside Fluid Engine and with custom CSS/media queries — to fine-tune the existing template and layout so every breakpoint feels polished and consistent.

Scope
• Focus strictly on design customization. Content, copy and SEO remain unchanged.
• Work on the current template; I’m not looking to switch themes, only to adjust how rows, blocks and galleries respond as screen sizes shrink or expand.
• Typical trouble spots include overlapping images, irregular column stacking, and inconsistent padding/margins.

Deliverables
1. Updated layout settings or injected CSS that fixes the responsive issues across mobile, tablet and large-screen views.
2. Clear notes or Loom walkthrough showing where code was added and how I can tweak it in the future.
3. A quick post-deployment check to confirm the fixes hold once I republish.

If you’ve solved similar responsive hiccups on Squarespace before, especially using the Fluid Engine editor, please let me know. I can provide edit access right away and expect this to be a focused, quick-turn task.
