#frontend #performance #webdev #shopify

Weekly Sprint Report: February 4 – February 6, 2026

This week, we executed a comprehensive technical overhaul of the Oatopia Shopify theme. Our focus shifted from foundational modernization of legacy assets to high-level performance tuning and UX polishing.

⚡ Performance & Core Web Vitals

Speed is a feature. We spent significant time reducing page weight and optimizing how the browser handles our most important assets.

Image Modernization: Conducted a project-wide audit to replace legacy filters (img_url, file_img_url, asset_img_url) with the modern image_url standard.
Next-Gen Delivery: Enabled automatic WebP/AVIF delivery via Shopify CDN and implemented loading="lazy" for off-screen images.
LCP Optimization: Updated the collection banner to use fetchpriority="high", signaling the browser to prioritize the hero image immediately.
HTML Bloat Reduction: Refactored the QuickBuy feature to use a minimal manual JSON object instead of injecting massive data for every product card, drastically reducing page weight.
Asset Loading: Moved global.bundle.js to the end of the body to unblock rendering and implemented a "print" media trick for non-blocking Adobe Typekit fonts.

🗺️ Navigation & Header Architecture

We addressed several layout shifts and usability hurdles within the site's navigation.

Smart Hover Logic: Added a 150ms grace period to dropdowns and implemented auto-close logic for adjacent menus to prevent overlapping during mouse sweeps.
Desktop-to-Mobile Parity: Fixed an issue where secondary links like "Account" were missing from the mobile drawer by updating snippets/sidebar-nav.liquid.
Mega Menu Styling: Updated the layout to support a 3-column categorical structure (e.g., Shop > Oat Bakes, Flapjacks, Giftboxes).
Flexibility: Removed hardcoded CSS constraints to restore dynamic logo sizing based on theme settings.

🖌️ UI/UX & Visual Consistency

Refining the "feel" of the store to match the Oatopia brand identity.

Grid Stability: Optimized product grids to ensure rows are fully filled (no empty slots).
Mobile "Gap" Fix: Forced mobile 2-column grids to always be divisible by 2 to prevent "hanging" items at the end of a page.
Interactive Polish: Added a "Zoom + Bold" effect for dropdown items and increased horizontal padding on "View All" buttons for better prominence.
Brand Styling: Customized the footer "Subscribe" button with a Blueberry background and Demarara text.
Layout Fixes: Applied flex-nowrap to the header to prevent the Search and Cart icons from "squishing" on smaller desktop screens.

🛠️ Technical Fixes & SEO

Behind-the-scenes improvements for long-term site health.

Scroll Locking: Implemented JavaScript handlers for full body-scroll locking when menus are open to prevent secondary page scrolling.
SEO Hardening: Applied rel="nofollow" to all raw image thumbnail links to prioritize high-value page indexing.
Enhanced Product Blocks: Updated the product template schema to support multiple independent, per-product FAQ/Collapsible blocks.
Alpine.js Integration: Enhanced the menu state management using Alpine.js to handle hover delays and click-outside events effectively.

🏁 Conclusion

By the end of this sprint, all core modernization, performance optimization, and layout stabilization tasks have been completed and verified on the development theme. The site now boasts a significantly more robust navigation system and a leaner code architecture, particularly regarding image handling and HTML delivery
