  Verbose tl;dr

  The <select> element, long a styling holdout, is finally getting much-needed CSS customization capabilities in Chromium-based browsers. Developers can now style aspects like the dropdown arrow (using appearance: none and pseudo-elements), open state, and even the listbox itself, offering greater control over its visual presentation. This enables better integration with overall site design and improved user experience without resorting to JavaScript workarounds or custom elements. While some pseudo-elements are browser-prefixed, the changes pave the way for more consistently styled and accessible dropdown menus across the web.

  The Chromium team's blog post, "The <select> element can now be customized with CSS," proclaims a significant advancement in web development: the long-awaited ability to extensively style the <select> dropdown element using standard CSS. Historically notorious for its resistance to customization, the <select> element has presented a persistent challenge for web developers striving for consistent and visually appealing user interfaces across different browsers and operating systems. This new capability, now available in Chrome 117 and other Chromium-based browsers, finally grants developers the control they've desired.

  The blog post details how previously unstyleable aspects of the <select> element, such as the dropdown arrow (also referred to as the "indicator"), the appearance of options within the dropdown list, and the overall look and feel of the open and closed states, are now readily modifiable using standard CSS properties like appearance, background-color, border, color, font, padding, and more. This eliminates the need for complex JavaScript workarounds or reliance on third-party libraries to achieve custom styling, simplifying the development process and improving performance.

  Specifically, the appearance: none property now effectively removes the default browser-specific styling of the <select> element, providing a blank slate for developers to implement their own designs. This allows for seamless integration of the dropdown with the overall website aesthetic. The blog post further explains how to style specific parts of the <select> element, such as the dropdown options, using the ::part pseudo-element along with specific keywords like list, option, listbox, popup, and indicator. This granular control allows for precise customization of each element within the dropdown structure.

  Furthermore, the post highlights the ability to completely replace the default dropdown indicator with a custom image or icon using the background-image property in conjunction with the ::part(indicator) pseudo-element. This empowers developers to create visually distinctive dropdowns that align perfectly with their design vision. The ability to finally style the <select> element with CSS represents a major step forward in web development, offering greater flexibility and control over form element styling and contributing to a more consistent and visually appealing user experience across different platforms and browsers.

• I-cant-believe-its-not-webusb: Hacking around lack of WebUSB support in Firefox

  permalink

  Posted: 2025-03-14 08:36:08

  Verbose tl;dr

  This project demonstrates a workaround for Firefox's lack of WebUSB support by leveraging its native messaging capabilities. A small native application acts as a bridge, receiving commands from a web page via native messaging and interacting directly with USB devices. The web page communicates with this intermediary application using a custom, WebUSB-like JavaScript API, effectively emulating WebUSB functionality within Firefox. This allows web developers to write code that interacts with USB devices in a consistent manner across browsers, handling the Firefox difference behind the scenes.

  This GitHub project, "I-can't-believe-it's-not-WebUSB," addresses the frustration of Firefox users who want to interact with USB devices directly from web pages but are hampered by the browser's lack of WebUSB support. The project implements a workaround, not a true implementation of WebUSB, by leveraging Firefox's existing support for the serial API. Essentially, it acts as a bridge between a web page and a connected USB device.

  The core functionality revolves around a native messaging host application. This small program, written in Python, runs outside the browser and has direct access to the system's USB devices. On the web page side, a JavaScript library communicates with this native host using the browser's native messaging capabilities. When a web page needs to interact with a USB device, the JavaScript library formats the request and sends it as a message to the native host.

  The native host receives this message, parses the requested action, and then uses the pyusb library in Python to carry out the interaction with the specified USB device. The result of this interaction, whether it's data read from the device or a confirmation of a write operation, is then packaged into a response message and sent back to the JavaScript library in the browser. The library then makes this data available to the web page.

  This setup effectively circumvents the absence of WebUSB in Firefox. While it doesn't offer the same level of integration or security as a native WebUSB implementation, it provides a functional alternative for developers who need to access USB devices from Firefox. The project focuses specifically on USB CDC-ACM devices (Communication Device Class - Abstract Control Model), which are commonly used for serial communication, essentially treating the USB device as a virtual serial port. Therefore, its applicability is primarily for devices that use this communication standard. The reliance on a separate native host application adds a layer of complexity compared to the seamless experience offered by WebUSB in supporting browsers, but provides a practical, albeit somewhat cumbersome, solution for interacting with USB devices from Firefox.

• A Perplexing JavaScript Parsing Puzzle

  permalink

  Posted: 2025-03-12 14:46:02

  Verbose tl;dr

  Hillel Wayne presents a seemingly straightforward JavaScript code snippet involving a variable assignment within a conditional statement containing a regular expression match. The unexpected behavior arises from how JavaScript's RegExp object handles global flags. Because the global flag is enabled, subsequent calls to test() within the same regex object continue matching from the previous match's position. This leads to the conditional evaluating differently on subsequent runs, resulting in the variable assignment only happening once even though the conditional appears to be true multiple times. Effectively, the regex remembers its position between calls, causing confusion for those expecting each call to test() to start from the beginning of the string. The post highlights the subtle yet crucial difference between using a regex literal each time versus using a regex object, which retains state.

  The blog post "A Perplexing JavaScript Parsing Puzzle" by Hillel Wayne presents a seemingly straightforward JavaScript code snippet that produces an unexpected and counterintuitive result due to the intricacies of JavaScript's parsing rules. The puzzle revolves around the behavior of the ++ (increment) operator when combined with optional chaining (?.) and bracket notation for property access.

  Specifically, the code attempts to increment a property of an object that might not exist. It uses optional chaining to safely access the potentially missing property and then attempts to increment its value if it exists. The puzzle lies in the observed behavior differing depending on whether the property is accessed using dot notation or bracket notation.

  When dot notation is employed (e.g., object?.property++), the increment operation works as seemingly intended: if the property exists, its value is incremented; if it doesn't, nothing happens. However, when bracket notation is used with a string literal key (e.g., object?.['property']++), the code throws a ReferenceError. Even more perplexing, if bracket notation is used with a variable holding the property name (e.g., let key = 'property'; object?.[key]++), the code does not throw an error, but neither does it increment the property. Instead, the value of the property remains unchanged.

  Wayne meticulously dissects this behavior by delving into the complexities of the JavaScript specification, specifically the processes of parsing, evaluation, and the distinction between left-hand-side (LHS) and right-hand-side (RHS) expressions in assignments. He demonstrates how the parsing of these different syntactic constructs leads to different internal representations, which ultimately explains the divergent outcomes. The core issue arises from the way JavaScript handles assignments in conjunction with optional chaining. The optional chaining effectively short-circuits the evaluation if the base object is null or undefined. However, the increment operator requires an LHS reference to assign the incremented value. In the problematic cases, the parsing rules prevent the creation of a valid LHS reference when optional chaining is combined with bracket notation, leading to either a ReferenceError or a silently failing increment operation.

  The post concludes by highlighting the non-intuitive nature of this behavior and the challenges it poses for developers, especially considering the relative newness of the optional chaining feature. It serves as a cautionary tale about the subtle yet significant impact of seemingly minor syntactic variations in JavaScript and emphasizes the importance of understanding the underlying parsing rules to avoid unexpected pitfalls.

  Hacker News users discuss various aspects of the perplexing JavaScript parsing puzzle. Several commenters analyze the specific grammar rules and automatic semicolon insertion (ASI) behavior that lead to the unexpected result, highlighting the complexities of JavaScript's parsing logic. Some point out that the ++ operator binds more tightly than the optional chaining operator (?.), explaining why the increment applies to the property access result rather than the object itself. Others mention the importance of tools like ESLint and linters for catching such potential issues and suggest that relying on ASI can be problematic. A few users share personal anecdotes of encountering similar unexpected JavaScript behavior, emphasizing the need for careful consideration of these parsing quirks. One commenter suggests the puzzle demonstrates why "simple" languages can be more difficult to master than initially perceived.

  The Hacker News post titled "A Perplexing JavaScript Parsing Puzzle" (https://news.ycombinator.com/item?id=43343832) has generated a robust discussion with several compelling comments exploring the nuances of JavaScript's parsing behavior.

  Several commenters dive into the technicalities of the automatic semicolon insertion (ASI) rules in JavaScript, explaining how they contribute to the unexpected behavior highlighted in the linked article. They point out that ASI is not simply adding semicolons wherever they seem to fit, but follows a specific set of rules based on the grammar, leading to occasional counter-intuitive outcomes. One commenter notes that ASI is "notoriously confusing," even for experienced JavaScript developers, and emphasizes the importance of understanding these rules to avoid subtle bugs. Another commenter provides a detailed breakdown of how the JavaScript parser interprets the code snippet, showing step-by-step how ASI leads to the unintuitive result.

  Some comments focus on the practical implications of such parsing quirks. One commenter highlights how these unexpected behaviors can make debugging and maintenance more difficult, especially in larger codebases. Another user suggests using a linter or code formatter to enforce consistent coding style and catch potential ASI-related issues early on. They argue that preventative tools like linters are essential for avoiding subtle bugs caused by unexpected parsing.

  The discussion also touches upon the broader topic of language design. One commenter critiques the complexity of JavaScript's grammar and argues that such ambiguous parsing rules make the language more prone to errors. Another commenter offers a contrasting perspective, suggesting that while ASI might seem counterintuitive at first, it's a necessary mechanism for maintaining backward compatibility with older JavaScript code.

  Several comments offer specific solutions or workarounds to avoid the problem presented in the article. These include explicitly adding semicolons, using parentheses to clarify the intended grouping of expressions, and relying on linters to detect potential ASI-related issues. One commenter even provides an alternative way to write the code snippet that avoids the problematic ASI behavior altogether.

  Finally, some commenters express their surprise and amusement at the unexpected behavior demonstrated in the article, highlighting the sometimes-perplexing nature of JavaScript. One commenter remarks on how such puzzles can be a valuable learning experience, helping developers gain a deeper understanding of the language's intricacies. Another simply expresses their amazement, calling the behavior "truly bizarre." The comments collectively reveal a mix of technical analysis, practical advice, and shared bewilderment regarding JavaScript's intricate parsing rules.

  Verbose tl;dr

  Eric Meyer reflects on the ten years since the release of his book, "Designing for Performance," lamenting the lack of significant progress in web performance. While browsers have gotten faster, web page bloat has outpaced these improvements, resulting in a net loss for users. He points to ever-increasing JavaScript execution times and the prevalence of third-party scripts as primary culprits. This stagnation is particularly frustrating given the heightened importance of performance for accessibility, affordability, and the environment. Meyer concludes with a call to action, urging developers to prioritize performance and break the cycle of accepting ever-growing page weights as inevitable.

  Eric Meyer, in his June 7, 2024 blog post entitled "A decade later, a decade lost (2024)," reflects with a palpable sense of disappointment on the state of web development a decade after his original post in 2014 lamenting the stagnation of the field. He posits that the intervening ten years have not witnessed the advancements he had hoped for, specifically in the realm of layout tools. While acknowledging some marginal improvements, such as the wider adoption of Flexbox and Grid, he argues these developments have not fundamentally altered the landscape or resolved the core issues that plagued web design in 2014. He expresses particular frustration with the enduring prevalence of single-column layouts and the lack of substantial innovation in layout modules beyond Flexbox and Grid.

  Meyer details his earlier optimism for advancements inspired by the print design world, such as regions and exclusions, which have failed to materialize in any meaningful way. He laments the lack of development in areas like multi-column layout handling overflow, fragmentation, and spanning, emphasizing the limitations of existing tools when dealing with these complex scenarios. Furthermore, he notes the continued dominance of JavaScript frameworks and libraries, which he views as adding complexity and overhead while often failing to deliver truly novel or efficient layout solutions. He suggests these frameworks, while providing some structure, often obscure or even hinder access to the underlying CSS layout capabilities that could be leveraged for more elegant and performant design.

  His disappointment extends to the perceived lack of focus within the web standards community on pushing the boundaries of layout technology. He contrasts the relative stagnation in this area with the significant advancements made in other aspects of web development, such as the proliferation of new JavaScript frameworks. This, he suggests, implies a misdirection of effort and a lack of appreciation for the fundamental importance of robust and flexible layout tools. He concludes with a renewed plea for the development community to revisit and prioritize innovation in layout, arguing that the current state of affairs represents a significant missed opportunity and a detriment to the evolution of the web. He underscores the ongoing need for more advanced layout tools to unlock the true potential of the web platform and facilitate the creation of richer, more dynamic, and ultimately more user-friendly web experiences.

  Posted: 2025-02-05 19:08:12

  Verbose tl;dr

  Cloudflare is reportedly blocking access to certain websites for users of Pale Moon and other less common browsers like Basilisk and Otter Browser. The issue seems to stem from Cloudflare's bot detection system incorrectly identifying these browsers as bots due to their unusual User-Agent strings. This leads to users being presented with a CAPTCHA challenge, which, in some cases, is unpassable, effectively denying access. The author of the post, a Pale Moon user, expresses frustration with this situation, especially since Cloudflare offers no apparent mechanism to report or resolve the issue for affected users of niche browsers.

  A Hacker News user has reported that Cloudflare is seemingly blocking access to websites protected by its services when using the Pale Moon web browser, and potentially other less common browsers. The user describes encountering Cloudflare's "Checking your browser before accessing..." page, which typically precedes legitimate access but in this case never progresses, effectively denying access. This issue specifically arises with Pale Moon 29.4.1 (x64) on Windows 10. The user emphasizes that they have disabled all extensions and add-ons within Pale Moon, eliminating them as a potential cause of the blockage. They also note that clearing cookies and site data did not resolve the issue. The affected websites are served through Cloudflare, but the exact trigger for the block remains unclear. The user hypothesizes that Cloudflare might be targeting Pale Moon's User-Agent string, a piece of information browsers send to websites identifying themselves, speculating that Cloudflare may have a list of acceptable User-Agent strings and is blocking access from browsers with unrecognized identifiers. This suggests a potential incompatibility between Cloudflare's security measures and Pale Moon's browser identification. The user highlights the inconvenience this poses, particularly for users who rely on or prefer less mainstream browsers. The post implies a concern regarding the control Cloudflare exerts over web access and the potential for exclusion of legitimate users based on browser choice.
