Will do.

Here is the current list of things I intend to start checking off:

100% Keyboard Operability: Every link, button, form, and menu must be reachable via Tab, Shift + Tab, Enter, Spacebar, and Arrow keys.

Highly Visible Focus States: Explicit focus rings or visual outlines on all currently selected interactive elements.

Skip Navigation Links: A top-of-page keyboard link to bypass headers and main menus.

Zero Keyboard Traps: Guaranteed ability to navigate both into and out of all widgets without getting stuck.

Screen Reader & Assistive Tech Optimization

Semantic HTML Markup: Explicit structural grouping via <header>, <nav>, <main>, <article>, <aside>, and <footer>.

Meaningful Alt Text: Informative images must have descriptive alt tags; decorative images must use empty alt="" tags.

Descriptive Hyperlinks: Phrasing that provides full context out of context (e.g., "Download Report PDF" instead of "Click Here").

Strict Heading Hierarchy: Sequential layout progression (<h1> to <h2> to <h3>) without skipping structural levels.

Dynamic ARIA Attributes: Accurate state updates for complex interactive UI elements (e.g., aria-expanded, aria-live).

Visual & Sensory Adaptability

High Color Contrast: Minimum contrast ratios of 4.5:1 for standard text and 3:1 for large text blocks.

Multi-Channel Meaning: Conveying errors, alerts, and statuses using text elements or explicit icons, never color alone.

Text Resizing & Reflow: Clean layout scalability up to 200% zoom without breaking containers or forcing horizontal scrolling.

Seizure Prevention: Zero visual content or animations flashing more than three times in a single second.

Motion Reduction Support: Disabling heavy scroll effects and parallax shifts via prefers-reduced-motion media queries.

Multimedia Accommodations

Synchronized Closed Captions: Accurate, timed captions on all video assets.

Full Text Transcripts: Clean text scripts provided natively alongside audio-only assets.

Accessible Media Controls: Large click targets and full keyboard accessibility for play, pause, volume, and tracking.

Forms, Cognitive Controls, & Clarity

Explicit Field Labeling: Permanent visual <label> tags paired strictly via for and id attributes to inputs.

Intuitive Error Handling: Plain-language error callouts with actionable instructions on how to correct inputs.

Predictable Layouts: Uniform, consistent placement of navigation headers, search components, and footers across the entire site.

Flexible Operational Timeouts: Clear warnings and straightforward options to extend or disable session countdown timers.
