Accessibility Issues With Message Filter Text Scaling

The Challenge of Unresponsive Text in the Message Filter

Accessibility is a cornerstone of modern web design, ensuring that everyone, regardless of their abilities or how they interact with technology, can access and use digital content. For users with visual impairments or those who simply prefer larger text for easier reading, browser-based text resizing is a critical feature. It allows them to adjust the default font size to their comfort level, typically around 24px or greater. However, a recent issue has come to light concerning the message filter component on VA.gov, where specific elements fail to respect these user-defined text size settings. This not only creates a frustrating user experience but also presents a significant accessibility barrier, potentially preventing some users from effectively managing their messages. The problem statement clearly outlines that when a user sets their browser's default font size to 24px or larger, several components within the message filter do not scale up as expected. This includes the filter heading, which has a hardcoded font size of 20px and a line-height of 26px, meaning it won't grow proportionally with the user's preference. Similarly, the 'Show filters' accordion button suffers from a hardcoded width of 166px. This fixed width forces the text to wrap awkwardly, creating a visually unappealing and potentially confusing layout. Furthermore, the '+' button decorator, intended to indicate an expandable section, remains in a fixed position, leading to it overlapping the text when the text wraps due to the restricted width. This lack of responsiveness directly contradicts the principles of WCAG 2.2's SC 1.4.4 Resize Text, which mandates that content should be resizable without loss of information or functionality. The hardcoded values are the primary culprits, preventing dynamic adjustment based on user preferences. Addressing these hardcoded dimensions is paramount to ensuring the message filter is usable and accessible for all.

Deep Dive into the Message Filter's Accessibility Flaws

Let's delve deeper into the specific issues plaguing the message filter component and understand why they are critical from an accessibility standpoint. The problem statement highlights two main areas of concern: the filter heading and the 'Show filters' accordion button. For the filter heading, the hardcoded font-size of 20px and line-height of 26px are problematic. When a user increases their base font size to 24px, this heading should ideally scale up to remain legible and proportional to other text on the page. Instead, it remains fixed, becoming relatively smaller and potentially harder to read for users who rely on larger text. This fixed sizing can lead to a jarring visual experience, where certain text elements are significantly smaller than others, disrupting the overall visual hierarchy and making it harder to scan and comprehend information. Then there's the 'Show filters' accordion button. The hardcoded width of 166px is a particularly troublesome aspect. In responsive design, fixed widths are generally discouraged, especially for elements that contain text which may need to expand. When the text wraps due to this limited width, it creates an unprofessional and difficult-to-read presentation. Compounding this issue is the '+' button decorator. This icon, meant to visually signal an expandable section, is fixed in place. As the text wraps, the decorator can end up directly overlapping the text, making it unreadable and confusing. This overlap is a clear indication that the element's layout is not adapting to its content. Beyond these direct issues, there's a significant side issue worth discussing: the inconsistency between the 'Show filters' component and a similar component, 'What's a message ID?', located just above it. The 'What is a message ID?' component serves as a prime example of how to implement an accessible and user-friendly accordion or expandable section. Its accordion buttons, or triggers, span the full width of their containing element, allowing users to activate the section by clicking anywhere within that area. This provides a larger click target, which is beneficial for users with motor impairments. Furthermore, this component features a focus indicator that spans the entire click area, a hover state that also covers the full click area, and a smooth, time-based transition when opening. In contrast, the 'Show filters' component is far less accommodating. Its focus area is limited only to the button itself, and the hover state is only triggered when hovering directly over the button. This disparity creates an inconsistent user experience. The alignment of the 'Show filters' button is also visually off due to the extra margin and padding applied, further detracting from its usability. Crucially, it lacks the time-based transition found in the 'What is a message ID?' component, making its opening and closing feel abrupt and less polished. These inconsistencies not only affect usability but also signal a potential lack of adherence to design system principles and accessibility best practices across the platform.

The Path Forward: Solutions for Enhanced Accessibility

Resolving the accessibility issues within the message filter component requires a strategic approach focused on replacing hardcoded values with more flexible and scalable units. The proposed solution and next steps provide a clear roadmap for achieving this. The primary recommendation is to change font sizes to use rem units. The rem unit (root em) is relative to the font size of the root element (typically the <html> element), which in turn is often influenced by the user's browser default font size settings. By migrating font sizes from fixed pixels (px) to rem, the text within the filter heading and other elements will automatically scale up or down in response to the user's browser preferences. This is a fundamental step towards meeting the requirements of WCAG 2.2 SC 1.4.4 Resize Text. For instance, if the user has set their base font size to 24px, any element using rem units for its font size will proportionally adjust, ensuring legibility and maintaining the intended visual hierarchy. Alongside font size adjustments, the recommendation to change button width to use rem or % is equally vital. A fixed pixel width for the 'Show filters' button is the root cause of the text wrapping and overlapping issues. Using rem or percentage-based widths allows the button to adapt dynamically to the content it contains and the available space. A percentage-based width (%) would make the button responsive to its container, while rem units for width, similar to font sizes, would allow it to scale with the user's text size preferences, offering a more robust solution. Implementing these changes will not only fix the immediate problems of text overlap and poor wrapping but also ensure that the component is truly adaptable to diverse user needs. The acceptance criteria clearly state that fonts should scale relative to the base settings provided by the user's browser or system settings, and this is precisely what the proposed solutions aim to achieve. Moving forward, the tasks outlined are crucial for the development lifecycle. These include reviewing and refining feedback, updating ticket information to ensure clarity and proper tracking, and implementing the fixes or documenting any decisions made regarding the implementation. The involvement of a product manager for moving the ticket to 'QA/A11y Review' and an accessibility specialist for final validation and closure ensures a thorough and collaborative process. By adopting these flexible units, we move closer to a web experience that is truly inclusive and respects every user's individual needs.

Ensuring Consistency and User Experience

Beyond the technical implementation of rem units and responsive widths, there's a crucial aspect of accessibility and user experience that needs continuous attention: consistency. The side issue identified in the problem statement – the stark contrast between the 'Show filters' component and the 'What's a message ID?' component – highlights a broader challenge in maintaining a cohesive and predictable interface across VA.gov. The 'What is a message ID?' component, with its full-width clickable areas, encompassing focus indicators, hover states, and smooth transitions, sets a high bar for what users can expect from an interactive element. It's intuitive, forgiving, and visually clear. Conversely, the 'Show filters' component, with its limited click target, abrupt transitions, and misaligned button, falls short. This inconsistency can lead to user confusion and frustration. Users learn patterns as they navigate a website, and when these patterns are broken, it requires extra cognitive effort to understand how to interact with different elements. For users who rely on assistive technologies or have cognitive disabilities, this inconsistency can be a significant hurdle. Therefore, the proposed solutions should not only address the immediate resizing issues but also consider bringing the 'Show filters' component into alignment with the more accessible patterns demonstrated by 'What's a message ID?'. This means:

• Expanding the click and hover targets: Making the entire area of the accordion trigger clickable, not just the button itself, will improve usability, especially for those with motor challenges.
• Ensuring full-width focus indicators: This provides clear visual feedback to keyboard users about their current interactive element.
• Implementing smooth, time-based transitions: This makes the opening and closing of sections feel more natural and less jarring.
• Addressing margin and padding: These should be reviewed to ensure the button is visually aligned and doesn't contribute to a sense of awkwardness.

By prioritizing consistency and adopting best practices demonstrated by successful components, we enhance the overall usability and accessibility of the platform. This iterative improvement process, where we learn from existing components and apply those lessons to others, is key to building a truly user-centered digital experience. Ultimately, every component on VA.gov should strive to meet the highest standards of accessibility and intuitive design, ensuring that all users can navigate and utilize the site with confidence and ease. Ensuring that all interactive elements behave predictably and provide clear feedback is a critical part of building trust and facilitating efficient task completion for every visitor to the site.
