S76 Ep 7The Hidden Trouble with Tables
In this episode of Chax Chat, Chad and Dax tackle one of the most misunderstood areas of document accessibility: tables. While they may seem simple to build, the real challenge is designing them in a way that works for assistive technology. We break down how screen readers navigate tables, why column and row headers matter, and how small design decisions can dramatically impact the user experience. From common pitfalls like overcomplicated layouts and unclear headers to practical tips you can apply immediately, this episode is packed with real-world insight. Whether you create, design, or remediate documents, you'll walk away with a clearer approach to building tables that are not just accessible, but truly usable.
S6 Ep 6The One Remediation Tool You Should Have...
What's the best tool for making PDFs accessible? It's the question we get constantly, and the honest answer might surprise you. There isn't one. In this episode of Chax Chat, Chad and Dax break down how the "best" accessibility tool depends entirely on your starting point. Are you working in Word, InDesign, PowerPoint, Google Docs, or Canva? Do you have a tagged PDF, an untagged PDF, or a scanned document? Each scenario changes the strategy. We discuss why "born accessible" is always better than heavy remediation, when Adobe's auto-tagging can actually help, why tools like MadeToTag and Access Word continue to be game changers, and how platforms like CommonLook, PDFix, PREP, and Grackle fit into the workflow. We also talk about handling scanned PDFs, the realities of screen reader testing, and why bookmarks aren't the navigation solution many people think they are. If you've ever felt overwhelmed trying to choose the right accessibility tool, this episode will help you stop chasing a magic solution and start making smarter decisions based on context. Every other week, we unravel accessibility so you can build more inclusive, compliant, and practical documents.

S6 Ep 5Microsoft's MathML Win and Adobe's AI Alt Text Experiment
In this episode of ChaxChat, Dax Castro and Chad Chelius unpack two very different approaches to accessibility innovation. First, they dive into Microsoft's implementation of MathML in Word and PowerPoint and why it represents a genuine win for accessible math. By carrying MathML through to the PDF export with proper tagging and screen reader support, Microsoft demonstrates what it looks like when accessibility is built into the workflow rather than patched on later. They then turn to Adobe InDesign's new AI-generated alt text feature and explore where it helps, where it falls short, and why turning it on by default raises important concerns. The conversation highlights the difference between proven accessibility solutions and experimental AI features, emphasizing the need for human oversight, informed decision-making, and realistic expectations as tools continue to evolve.
S6 Ep 4Accessible Forms: PDF or Web?
Accessible forms are more than a technical checklist. They require smart decisions about usability, workflow, and long-term maintenance. In this episode of Chax Chat, Dax Castro and Chad Chelius are joined by Walt Zielinski, a web developer with extensive experience building accessible form experiences. The conversation focuses on a key question: when should you use a web form versus a PDF form? Together, they explore real-world considerations like data collection, offline access, cost, maintenance, and who is responsible for supporting the form over time. They also cover common accessibility issues that frequently get overlooked, including error identification, focus order, color reliance, target size, and the correct use of checkboxes and radio buttons. This episode offers practical guidance for designers, developers, and document professionals who want forms that actually work for everyone.

They unpack why tables and forms continue to be the most persistent pain points for document accessibility, discuss hard-earned wins from complex remediation projects, and reflect on where current tools still fall short. The conversation also explores realistic expectations for AI in accessibility, emerging assistive technologies that show genuine promise, and the conferences and community spaces shaping the year ahead. It is an honest, practical discussion grounded in experience, aimed at helping accessibility professionals and content creators learn from the past while preparing for what comes next.

Join Dax Castro and senior trainer Rob Underwood as they unpack how smarter file management and planning can transform your accessibility projects. They dig into practical strategies for setting up metadata, creating consistent heading structures, choosing and managing accessible color palettes with CC Libraries, and planning alternate formats for charts and tables before you ever hit export to PDF. Along the way, they tackle the realities of inherited files, layout tables, and multi-person workflows, showing how clear roles and reusable systems can save hours of remediation time while creating a better experience for everyone. Note: For Rob's layer shortcut, he meant to say bring to front, not send to back.
S5 Ep 21Accessible Color Without Killing Your Design
Does accessibility really mean ugly charts, boring colors, and pattern fills everywhere? In this episode, Chad Chelius and Dax Castro tackle accessible color head-on: what color contrast actually means, when it applies (and when it doesn't), and how to handle charts, graphs, heat maps, and logos without trashing your brand. They break down the key WCAG contrast ratios, talk about the logo exemption, and share practical strategies like smarter legends, labels, and selective use of patterns instead of "pattern fill everything." Learn how building an accessible brand palette up front can save hours of rework, and how thoughtful body text and alt text work together for complex graphics. If you've ever been told "accessibility makes our visuals look terrible," this episode will help you push back with solid reasoning and better design.
S5 Ep 20Are You Fixing the Wrong Thing?
Are you spending hours "fixing" things in a PDF that your screen reader users will never notice? In this episode Chad Chelius and Dax Castro ask a hard question: Are you fixing the wrong thing? We pop open the tags tree and talk about what really affects user experience and what is just busywork. From span tags and container tags that never get voiced, to lists that read like run-on paragraphs, to title tags vs H1s, role maps, and tables without proper scope, we walk through where your time actually matters. If you have ever deleted 200 span tags by hand, fought with a list that "looks fine," or wrestled with complex tables in Acrobat, CommonLook, or axesPDF, this episode will help you rethink your workflow and prioritize the fixes that make a real difference for assistive technology users.
