↻ 2026-07-30 Updated Refreshed the timeline: added the 3 March 2026 Working Draft milestone and revised the completion outlook against the working group’s schedule (CR snapshot targeted for Q4 2027). Introduction “Our site passed WCAG 2.1 AA 100%, but screen reader users still can’t sign up.” I keep thinking about this comment I heard at a conference last year. They passed accessibility audits, got the green badge, but users with disabilities still couldn’t use core features. This is the biggest dilemma facing WCAG 2.x today. ...

Introduction Recently, I started building and operating a blog using Hugo with the PaperMod theme. Using someone else’s theme has the advantage of quick setup, but not everything fits my needs perfectly. After customizing many parts to match my preferences, I noticed some issues with the code blocks. Line numbers were implemented with <table> tags. While this doesn’t violate accessibility guidelines, it felt not semantic. Moreover, I wondered: what’s the experience for screen reader users? I found a better approach using CSS Counters. ...

This post is a record of grappling with web accessibility, public web services, and the responsibilities of developers from direct, hands-on experience. Between law, technology, standards, and reality, I try to answer the question: “Are we really building for everyone?” In the previous post, we confirmed that the Digital Inclusion Act asks “what is usable?” Then this question remains: If AI is a system that makes decisions? If users can’t understand automated decisions? How do we distinguish between content created by generative AI? ...

This post is a record of grappling with web accessibility, public web services, and the responsibilities of developers from direct, hands-on experience. Between law, technology, standards, and reality, I try to answer the question: “Are we really building for everyone?” ↻ 2026-08-12 Updated Cross-checked against the enacted statute and corrected an article-number error. “Providing alternative means so services can be used without intelligent information technology” is Article 4, not Article 21, in the enacted law. Article 21 covers accessibility quality certification. The draft bill’s numbering had been carried over by mistake. In the previous post, we reached this question: ...

This piece is a record of wrestling with web accessibility, public services, and a developer’s responsibility from the field. Between law and technology, between standards and reality, I try to answer: “Are we really building for everyone?” While working on web accessibility for years, I found myself repeatedly hearing a similar question: “We’re certified and passed the checklist. Isn’t accessibility done now?” When I first heard this question, I nodded briefly. Many public websites did meet WCAG 2.1 / KWCAG 2.2 standards, passed screen reader tests, and satisfied contrast requirements. ...

Introduction I just returned from the AI Agent Scenario Competition Citizen Evaluation Panel held in Seoul. The panel consisted of expert judges and citizen evaluators, with the final scores reflecting both expert evaluation and citizen evaluation. Since the evaluation details are confidential, I can’t discuss individual teams or specific results. However, through this experience, I was able to clearly define what standards I use when evaluating AI public services. So in this post, rather than “how this team performed,” I want to record what questions I asked and why I thought those questions mattered. ...

Introduction Let me be honest — this choice is a losing deal on paper. I’m spending a whole day, paying for transportation out of my own pocket, and the compensation is only about $35 (50,000 KRW). Yet, I’m heading to Seoul tomorrow. I wanted to organize my reasons step by step. View from a train window - a journey to somewhere Photo: Dieter K / Unsplash The Evaluation Panel Offer and My Decision One day, while browsing the NIA (National Information Society Agency) website as usual, I discovered the Public Institution Website Citizen Evaluation Panel. Since then, I’ve been grateful to participate in the public web/app citizen evaluation activities for two years straight. The rewards and achievements may seem small, but the process and experience have been building up as personal assets. ...

Introduction As a web developer, you’ve probably encountered code like this: html Read line numbers: OFF Line-number reading help Reading line numbers aloud This button is for screen reader users. ...

Introduction We live in an age where generative AI like ChatGPT, Claude, and Gemini has become part of daily life. AI chatbots have established themselves on websites, and automated content generation has become commonplace. Amid this rapid technological advancement, we must ask an important question: “Is the web created by AI usable by everyone?” Web Accessibility means ensuring that everyone—people with disabilities, elderly users, those with slow network connections, and more—can use the web equally. In the AI era, or rather because it is the AI era, web accessibility has become even more critical. ...

🚀 Starting a New Blog Hello. This is a space where I record what I learn and experience, hoping it might be of some small help to someone. I call myself a “perpetual beginner developer.” There’s always so much to learn, and sometimes I repeat small mistakes, but recording and sharing this process is both my way of growing and my joy. Why Did I Start This Blog? When developing, you encounter countless trials and errors. Sometimes you panic at error messages you’ve never seen before, and sometimes you face the same problem again today that you solved yesterday. ...
