Bootstrap Regulatory Frameworks & Compliance 4

Question 1

A Bootstrap-powered healthcare site must comply with HIPAA. Which Bootstrap UI pattern poses the highest risk of unintentional PHI (Protected Health Information) exposure?

Accepted Answer

Toast notifications displaying patient status messages

Answer

Toast notifications can display sensitive status messages in the DOM and may be cached or captured by browser extensions, making them a HIPAA risk if they contain PHI without proper controls.

Question 2

Which Bootstrap JavaScript plugin requires explicit aria-expanded attribute management to comply with WCAG 2.1 SC 4.1.2 (Name, Role, Value)?

Accepted Answer

Collapse

Answer

Bootstrap's Collapse plugin must toggle aria-expanded on the triggering element to communicate the expanded/collapsed state to assistive technologies, per WCAG 4.1.2.

Question 3

Under the EU Web Accessibility Directive (WAD), public sector websites using Bootstrap must meet which standard?

Accepted Answer

EN 301 549 (which references WCAG 2.1 AA)

Answer

The EU Web Accessibility Directive mandates conformance with EN 301 549, which incorporates WCAG 2.1 Level AA as its core accessibility requirements for public sector sites.

Question 4

What is the primary compliance concern with using Bootstrap's data-bs-toggle='tooltip' on an icon-only button with no visible label?

Accepted Answer

Tooltips are not keyboard-focusable by default, violating WCAG 2.1.1

Answer

WCAG 2.1.1 requires all functionality to be operable by keyboard; Bootstrap tooltips on icon buttons are visible on hover but may not be reliably triggered by keyboard focus alone without additional implementation.

Question 5

Which Bootstrap feature directly supports compliance with WCAG 2.1 SC 1.4.4 (Resize Text), requiring text to be resizable up to 200% without loss of content?

Accepted Answer

Bootstrap's use of rem units for typography and spacing

Answer

Bootstrap uses rem-based font sizes and spacing, which scale proportionally when users resize text in browser settings, unlike px-based values that remain fixed regardless of user preferences.
