Text-based web browsers like Lynx, w3m, and ELinks are falling behind as HTML evolves. A technical analysis reveals how these browsers fail to handle modern interactive elements, creating a progressive enhancement paradox.
The web development community has embraced a philosophy of progressive enhancement for decades: start with solid HTML, then layer CSS and JavaScript on top. This approach theoretically ensures that content remains accessible regardless of the user's browser capabilities. Yet a troubling reality emerges when we examine how text-based browsers—those minimalist tools like Lynx, w3m, and ELinks—actually handle modern HTML features. The gap between what HTML can do and what these browsers understand is growing, not shrinking.
The baseline assumption
When developers talk about cross-browser compatibility, they typically mean Chrome, Firefox, Safari, and Edge. Text-based browsers exist in a blind spot, dismissed as relics or niche tools for terminal enthusiasts. But they serve important purposes: they're invaluable for accessibility testing, useful in resource-constrained environments, and surprisingly effective for developers who want to verify their markup is semantically sound without the distraction of visual styling.
The core premise of progressive enhancement suggests that if we build properly with HTML first, we should be covered. The reality is more complex. Modern HTML has evolved to include interactive elements that don't gracefully degrade in text-based environments—they simply don't work at all, often breaking the user experience in ways that violate the progressive enhancement ideal.
Details and disclosure widgets
The <details> element provides native disclosure functionality without JavaScript. When closed, it shows only the <summary>. This is elegant for progressive enhancement: without CSS or JS, it still functions as a simple expandable section.
Text-based browsers don't understand this semantic. They render the entire contents of <details> elements as if they were always open. The result is verbose but functional—users see all content, which is acceptable for most use cases. The verdict here is "acceptable" because while the interactive behavior is lost, the content remains accessible.
Data lists and input suggestions
The <datalist> element attaches suggested values to input fields, creating a simple autocomplete experience. Here, text-based browsers show a more fundamental problem: they often ignore datalists entirely. Lynx even flags them as "bad HTML," apparently because it expects <option> elements only within <select> elements.
The browsers fall back to a plain <input> field, which is better than nothing. The verdict is "whatever"—a pragmatic acknowledgment that this failure is minor, especially given that datalists have known accessibility issues anyway.
Dialogs: where things get problematic
The <dialog> element brought native modal and non-modal dialogs to HTML. Initially requiring JavaScript to toggle visibility, the Popover API now enables much of this functionality with plain HTML. This represents a significant step toward the progressive enhancement ideal.
Text-based browsers have no support for dialogs. They render all dialog content as if the open attribute were always present. Worse, they don't understand method="dialog" on forms, so submitting a dialog triggers the form action instead of closing the dialog cleanly. This breaks expected behavior and can lead to confusing user experiences. The verdict is "problematic"—the loss of functionality here is more severe.
Popovers and the Invoker Commands API
The Popover API is one of the most exciting recent additions to HTML, enabling lightweight, dismissible UI overlays without JavaScript. Since dialogs are essentially a type of popover, it's no surprise that text-based browsers handle them the same way: they dump all popover content onto the screen.
The verdict is "most likely problematic," and the pattern is becoming clear. These aren't just missing features—they're interactive elements that fundamentally change how content is presented and accessed.
Inert content areas
The inert attribute makes entire sections of the DOM unreachable for interaction, a crucial tool for modal dialogs and focus management. Without it, developers must manually disable interactive elements within overlays.
Text-based browsers ignore inert entirely. Users can still access and interact with links, buttons, and forms inside areas that should be inert. This creates accessibility and usability problems that can trap users in broken interfaces. The verdict is blunt: "Bad."
The hidden attribute: the breaking point
Here we reach the feature that prompted this article. The global hidden attribute has been supported for over a decade, providing a native way to hide content in HTML, equivalent to display: none in CSS. This is fundamental to progressive enhancement techniques where content starts hidden and becomes visible through CSS or JavaScript.
Text-based browsers never implemented hidden support. Discussions about adding it were rejected years ago. The result: all content marked with hidden remains visible.
This isn't a minor omission—it's a fundamental violation of the progressive enhancement contract. Developers use hidden specifically to control content visibility at the HTML level, often for critical progressive enhancement patterns. When text-based browsers ignore it, they break the intended behavior completely.
The verdict is damning: "Epic fail." This isn't just about missing features; it's about browsers that actively undermine the core philosophy of building with HTML first.
The visually hidden problem
There's no native HTML way to visually hide content while keeping it accessible to screen readers. Developers rely on CSS classes like .visually-hidden or .sr-only, which require multiple lines of CSS. If HTML had a native solution, text-based browsers would display it anyway, since they ignore styling. This remains an unsolved problem.
The progressive enhancement paradox
Here's the irony: text-based browsers were supposed to be the safety net for progressive enhancement. They were meant to prove that good HTML works everywhere. Instead, they've become the exception that proves the rule: modern HTML features require browser support, and without it, the entire approach breaks down.
The gap isn't closing. As HTML continues to evolve with features like the Popover API, Invoker Commands, and future interactive elements, text-based browsers are falling further behind. The choice for developers becomes stark: either limit HTML to what text-based browsers understand, or accept that these browsers will provide a broken experience for modern sites.
What this means for web development
This analysis reveals a deeper tension in web development philosophy. The progressive enhancement ideal assumes that browsers will gracefully handle markup they don't understand. But modern HTML features aren't just decorative enhancements—they're interactive components with specific behaviors.
When text-based browsers ignore hidden attributes, they don't just miss styling cues; they fundamentally misunderstand the document structure. When they render dialogs as static content, they break the expected interaction model.
For developers who care about these browsers, the options are limited:
- Avoid modern HTML features entirely, sticking to basic markup that text-based browsers understand
- Accept the degradation and hope users understand they're seeing a broken experience
- Use server-side detection to provide alternative experiences
None of these is ideal. The first option sacrifices modern web capabilities. The second violates the principle of universal access. The third adds complexity and maintenance burden.
The future of text-based browsers
The trajectory is concerning. As the web becomes more interactive by default—through native dialogs, popovers, and other features—text-based browsers risk becoming obsolete not through obsolescence of their concept, but through their inability to keep pace with HTML itself.
W3m, Lynx, and ELinks were built for a web of documents. The modern web is a platform for applications. The two visions are increasingly incompatible.
This doesn't mean text-based browsers have no value. They remain excellent tools for testing semantic markup, verifying accessibility structures, and providing access in constrained environments. But their role as a universal fallback is diminishing.
A call for reconsideration
The text-based browser community might need to reconsider its position. Features like hidden support aren't stylistic flourishes—they're fundamental to how modern HTML works. Implementing them wouldn't mean rendering visual styles; it would mean respecting the semantic meaning of HTML attributes.
Without this evolution, the gap will indeed widen. These browsers won't die overnight, but they'll become increasingly irrelevant to the modern web development conversation. The progressive enhancement ideal they once represented will need new champions.
For now, developers building with modern HTML must accept that text-based browsers will provide a subpar experience. The question becomes whether that's a price worth paying for using features that make the web better for the vast majority of users on modern browsers.
The answer, for many, will be yes. And that reality, more than any technical limitation, is what might ultimately relegate text-based browsers to history.
