WalkthroughRemoved the jQuery-based FitVids plugin and the jQuery 3.5.1 inclusion. Added a small vanilla JS initializer for mobile menu toggling (assets/js/init.js). Updated CSS to enforce 16:9 aspect ratios and overflow handling for article images and embedded iframes (YouTube, Vimeo, Kickstarter) and regenerated the built stylesheet.

1-1: Pre-existing CSS lint issues detected.The static analysis hints flag several issues (deprecated
word-break: break-word,grid-gap→gap, vendor prefixes, etc.) that are pre-existing in the codebase, not introduced by this PR. The built output correctly reflects the source CSS changes.Consider addressing these in a follow-up PR to modernize the CSS codebase:

Enhance video responsiveness using CSS-only solutions, remove jQuery dependencies, and optimize loading strategies for images and scripts to improve overall performance. Implement mobile menu functionality with vanilla JavaScript.
This pull request focuses on improving performance, modernizing responsive video handling, and enhancing image loading for better user experience. The main changes include removing the legacy
fitvids.jsdependency in favor of a pure CSS solution, optimizing image loading with native browser attributes, and updating script loading for efficiency.Responsive Video Handling:
jquery.fitvids.jsscript and all related jQuery code, replacing it with a pure CSS solution for responsive video embeds using theaspect-ratioproperty. [1] [2]16/9aspect ratio and full width to embedded iframes from popular video platforms, eliminating the need for JavaScript.Image Loading Optimization:
fetchpriority="high"andloading="eager"attributes to key images (cover images, author images, and feature images) inauthor.hbs,index.hbs, andpost.hbsto prioritize their loading and improve perceived performance. [1] [2] [3] [4] [5]Script and Dependency Management:
default.hbs; now, only the maincasper.jsscript is loaded with thedeferattribute for non-blocking rendering.init.jsto handle the mobile menu toggle, replacing the previous jQuery-based approach.Performance Improvements:
default.hbs.Pagination and Layout Enhancements:
16/9aspect ratio andoverflow: hiddento the.paginationcontainer for improved layout consistency.Note
Medium Risk
Front-end bundle changes that alter responsive video behavior and header navigation interactions; regressions would be user-visible but are limited to theme UI/UX.
Overview
Updates the built
casper.jsbundle to remove thefitVids(jQuery/Zepto) responsive video logic, relying on non-JS responsiveness instead.Adds a vanilla JS mobile burger-menu toggle that sets
aria-expandedand toggles thegh-head-openbody class, while leaving existing lightbox, dropdown nav, and infinite scroll behavior intact.Reviewed by Cursor Bugbot for commit eb2898d. Bugbot is set up for automated code reviews on this repo. Configure here.
