CSS position sticky is a relatively recent addition to web development that allows elements to toggle between relative and fixed positions based on the scroll position, offering a GPU-accelerated alternative to JavaScript scroll handlers. Before its official introduction, developers achieved similar functionality using JavaScript, but with significant performance drawbacks due to CPU reliance. Despite its potential, CSS sticky was initially underutilized due to delayed browser support, with major browsers like Google Chrome only adopting it in 2017. However, its usage is growing as developers leverage it for innovative web designs, such as sticky headers, footers, images, and navigation bars, despite challenges like managing overflow properties and ensuring accessibility. Cross-browser compatibility remains a concern, especially with Internet Explorer, which never supported the feature due to its deprecation. Tools like LambdaTest help developers test CSS sticky across numerous browsers and operating systems, facilitating broader adoption and implementation in web design.
