Country flag icons for inline and block display with CSS classes, useful for language selectors, location labels, and compact visual markers.

Address data is full of edge cases that break naive assumptions about location, format, and identity. Postal and street addresses often vary by country, purpose, and delivery system.

Quick RSpec-to-Jasmine 2 reference for matching expectations and mock assertions when switching test style; Jasmine 1.x uses different syntax.

Browser navigation during pushState or replaceState tests can leave Jasmine on the wrong URL and break test reruns. Saving and restoring the location keeps the suite on the spec page.

Jasmine DOM testing is easier with matchers like toBeVisible() and toHaveCss(css), plus fixture loading for temporary HTML setup and cleanup.

Native Ruby HTTP client setup can fail when the libcurl development package is missing. Installing the curl headers on Ubuntu 14.04 allows typhoeus to build and install.

Parallel Selenium features can time out when Capybara waits too little for browser-server interactions; a support file increases patience for @javascript scenarios.

Responsive JavaScript lightbox for single images and galleries, with optional animations and straightforward setup.

Command-line tool for Postgres databases with auto-completion and syntax highlighting, making interactive SQL work faster and less error-prone.

animate is chainable, so it does not return a completion handle. promise() provides a way to run code after the animation finishes.

jQuery .animate() can feel choppy because it relies on JavaScript timers, while CSS transitions deliver smoother motion with nearly the same API.

Provides JavaScript with a simple API for Ruby on Rails model CRUD, useful when direct browser access to create, read, update, and delete operations is needed.

ngRepeat with track by can silently prevent filters from running when placed before them; putting track by last preserves ordering.

Caching HTTP responses in the server based on an individual cookie can speed delivery, but cache invalidation remains unresolved.

A pure Sass mixin library for writing CSS3 with minimal setup. Vendor prefixes are built in for broad browser support and graceful fallback.

Uploaded test files can linger after Cucumber feature runs; placing cleanup code in features/support/ removes them automatically.
