  A developer created a charming animated scroll bar companion that "walks" down the webpage as you scroll. The little figure, seemingly inspired by platformer video games, is positioned alongside the scrollbar and mimics the user's scrolling action, creating a playful and visually engaging browsing experience. Its movement is synchronized with the scroll position, giving the impression of the character traversing the page's content. The project showcases a simple yet effective way to enhance the user interface with a touch of whimsy.

  A web developer has meticulously crafted and documented the creation of a charming, interactive scroll bar companion. This "scroll buddy," a small animated character situated adjacent to the webpage's vertical scroll bar, mimics the user's scrolling behavior, creating a sense of companionship and whimsy during navigation. The developer meticulously details the technical process, encompassing the JavaScript coding required to dynamically adjust the character's vertical position in real-time as the user scrolls. The implementation involves carefully calculating the proportional relationship between the scroll bar's thumb position and the overall scrollable document height, subsequently translating this into a corresponding vertical offset for the scroll buddy image. This ensures the character appears to "walk" down the page in perfect synchronization with the user's scrolling actions. The post extensively covers the challenges encountered and solutions devised, including strategies for handling varying screen sizes and potential performance implications. Furthermore, the developer showcases the versatility of the technique by demonstrating its adaptability to different character images and sizes, thereby allowing for personalization and customization of the scroll buddy experience. The result is a delightful enhancement to the otherwise mundane act of scrolling, injecting a touch of personality and interactivity into web browsing.

• A bookmarklet to kill sticky headers (2013)

  Verbose tl;dr

  This blog post presents a simple bookmarklet designed to remove fixed position headers on websites. The author, frustrated by obstructive sticky headers, created a JavaScript snippet that can be saved as a bookmark. When clicked, this bookmarklet iterates through all elements on the current page, identifies those with a fixed position (typically headers), and sets their position to static, effectively removing the sticky behavior. The post highlights the bookmarklet's effectiveness in reclaiming screen real estate and improving the browsing experience. It also includes the code snippet for easy copying and implementation.

  In a 2013 blog post titled "A bookmarklet to kill sticky headers," author Alasdair McDiarmid presents a JavaScript bookmarklet designed to remove fixed or "sticky" headers from web pages. He explains that while these headers can be useful in some contexts, they often obstruct content and become an annoyance, particularly on smaller screens where vertical real estate is precious. He identifies the primary CSS property responsible for this behavior as position: fixed; applied to the header element.

  McDiarmid provides the full JavaScript code for the bookmarklet, which iterates through all elements on the page. For each element, it checks if the position style is set to fixed. If it is, the script changes the element's position to absolute, effectively removing the fixed positioning and allowing the header to scroll with the rest of the page content. He emphasizes the simplicity and effectiveness of this approach, noting it doesn't require complex parsing or manipulation of the page's stylesheets.

  The author further explains how to create and use a bookmarklet: copying the provided JavaScript code and creating a new bookmark in the browser with the code pasted in as the URL. Clicking this bookmark on any webpage will then execute the script, modifying the fixed headers as described. He acknowledges the potential for unintended consequences, admitting that the script might affect elements other than headers that use position: fixed. However, he suggests the benefits of quickly disabling sticky headers generally outweigh this risk. The post concludes with the complete bookmarklet code, ready to be copied and used by readers.

Some users expressed concerns about potential website breakage, while others offered alternative solutions like browser extensions (e.g., uBlock Origin) or Stylish. A few commenters suggested improvements to the bookmarklet's code, such as handling elements with position: fixed differently or providing an option to restore the original header. The discussion also touched upon the broader issue of intrusive web design and the ongoing battle between users and websites trying to maximize ad revenue. One commenter even shared a personal anecdote about creating a similar tool years prior, highlighting the long-standing frustration with sticky headers.
