Accessibility Statement

Last updated: 12 April 2026

Astera Technology Limited is committed to making our digital presence usable by everyone, including people who rely on assistive technologies. This statement explains our current accessibility posture, the known gaps, and how to reach us if something isn't working for you.

Standard we target

asteratek.com is designed to conform to the Web Content Accessibility Guidelines (WCAG) 2.1, Level AA, as published by the World Wide Web Consortium (W3C). This is the most common benchmark for modern accessible web content.

What we already do well

• Semantic markup: the site uses proper heading hierarchy, landmarks (<header>, <main>, <nav>, <footer>, <section>), and descriptive link text.
• Keyboard navigation: all interactive elements (nav, form fields, buttons, language toggle, currency toggle) are reachable and operable via keyboard alone.
• Reduced motion: we honour the prefers-reduced-motion media query. Ambient Three.js scenes and hover-lift effects automatically disable for users who prefer reduced motion.
• Alt text: meaningful images carry alternative text; decorative illustrations use empty alt="" so screen readers skip them.
• Colour contrast: body text is a dark slate on light backgrounds with a measured contrast ratio > 7:1 (AAA).
• Forms: every form input has a visible, programmatically-associated <label>, and required fields are marked.
• Language switching: the page's lang attribute is updated when Traditional Chinese is selected, so screen readers pronounce content in the correct language.

Known limitations

We are honest about the gaps. As of the last-updated date above, we are aware of the following:

• Decorative canvas animations: the hero and pricing sections include Three.js particle scenes. These are layered behind the content and marked aria-hidden="true", but they do consume GPU. They are automatically disabled for reduced-motion users.
• Third-party icon fonts: we use Font Awesome, which loads from a CDN. On very slow or blocked connections, icon glyphs may momentarily appear as empty squares before the webfont loads.
• No live captions: the site does not currently host video content. If we add video in the future, captions and transcripts will be provided.
• Formal audit pending: this statement is self-assessed. We intend to commission an independent WCAG audit once the site has been live for a full quarter.

Assistive technology we test with

The site has been smoke-tested with:

• Built-in browser zoom up to 200%
• macOS VoiceOver on Safari
• Windows Narrator on Edge
• Keyboard-only navigation (Tab, Shift-Tab, Enter, Space)

Tell us if something's broken

If you encounter an accessibility barrier on this site — a missing label, a trap, an unreadable colour, anything — please let us know. We take accessibility feedback seriously and aim to respond within 5 business days.

Our philosophy on accessibility in client work

When we build software for clients, accessibility is part of the definition of “done”, not an afterthought. We ship features that keyboard users, screen-reader users, and colour-blind users can all use from day one — because retrofitting accessibility later costs 10× more.
