Resize Text
Except for captions and images of text, text must be resizable up to 200% without loss of content or functionality.
What it requires
Users with low vision rely on browser zoom (Ctrl/Cmd +) and per-element text resize. WCAG 2.0 SC 1.4.4 requires every page to remain usable when text is resized to 200% — no clipped content, no horizontal scrolling on body text, no broken layout, no buttons with overflowing labels.
The most reliable way to satisfy 1.4.4 is to size text with relative units (`rem`, `em`, `%`) rather than absolute pixels, and to use `max-width` on containers instead of fixed widths.
Common Shopify failure
Hero copy set in `font-size: 18px` and absolute-positioned over a fixed-height background image — at 200% zoom the copy overflows the image and gets clipped. Sticky announcement bar set to `height: 36px` with no overflow handling.
How to fix it
AccessComply's deterministic-fix pipeline rewrites `font-size: <px>` declarations to `rem` equivalents on theme stylesheets and removes fixed-height containers from layout-blocking sections (announcement bar, sticky header).
Merchant QA checklist
- Scan the storefront page where this pattern appears: product pages, collection pages, cart drawer, customer-account pages, and any landing page built with theme sections.
- Confirm the issue is fixed in the rendered browser output, not only in the Liquid file. Shopify section settings, app blocks, and third-party scripts can reintroduce the same 1.4.4 failure after a theme edit.
- Re-test the affected component with keyboard navigation and a screen-reader accessibility tree before publishing the theme, especially when the fix changes markup or ARIA attributes.
How AccessComply handles it
AccessComply treats WCAG 1.4.4 as a rendered-storefront issue first. The scanner checks the live DOM and computed styles, maps the finding back to the Shopify theme file that produced it, then classifies the fix as a guided partial fix. When automation is safe, the app writes the smallest theme-code change needed and keeps the original theme backup available. When merchant judgment is required, the issue is surfaced for manual review instead of pretending the page is fixed.
