Improving input responsiveness in Microsoft Edge
As the web becomes more interactive, web pages are becoming increasingly reliant on JavaScript for core functionality, such as input, rendering, layout, and composition. As more and more of this core functionality moves to the client side, it becomes imperative for browsers to adopt smart scheduling mechanisms to ensure that JavaScript workloads are processed in an efficient manner. With EdgeHTML
What forces layout/reflow. The comprehensive list.
what-forces-layout.md What forces layout / reflow All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck. Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for a

This browser tweak saved 60% of requests to Facebook
Over the past two years Facebook has been working with browser vendors to improve browser caching. As a result of this work, both Chrome and Firefox recently launched features that make their caches significantly more efficient both for us and for the entire web. These changes have helped reduce static resource requests to our servers by 60% and as a result have dramatically improved page load tim
history pushState and scroll position
I am trying to retrieve the scroll position when a user navigates back in the browser history using HTML5 popstate handler. Here is what I have: $(document).ready(function () { $(window).on('popstate', PopStateHandler); $('#link').click(function (e) { var stateData = { path: window.location.href, scrollTop: $(window).scrollTop() }; window.history.pushState(stateData, 'title', 'page2.html'); e.prev
History API - Scroll restoration | Blog | Chrome for Developers
Using the History API to manage your URLs is awesome and, as it happens, a crucial feature of good web apps. One of its downsides, however, is that scroll positions are stored and then, more importantly, restored whenever you traverse the history. This often means unsightly jumps as the scroll position changes automatically, and especially so if your app does transitions, or changes the contents o
Make the Web Work For Everyone – Mozilla Hacks - the Web developer blog
Updated 2016/07/22: Commenters found a few data errors (thanks!) which have now been corrected. Millions of websites have compatibility problems on one or more of the major browsers, leading to a poor user experience. The web developer community can fix this. The web has changed immensely in the past 20 years. In 1996 there were roughly a million websites; now there are more than a billion. Back t
Updating Our Prefixing Policy
When implementing new features for the Web, it’s important for us to be able to get them into the hands of developers early, so they can give new things a try. (Of course, this also helps us identify and fix bugs!) In the past, browsers did this by using vendor-prefixed names for features. This was intended to protect the Web from the churn of spec and implementation changes. Browsers would eventu
More Responsive Tapping on iOS
WebKit on iOS has a 350 millisecond delay before single taps activate links or buttons. WebKit has this delay because we also allow users to double tap to zoom, which is a great way to zoom in on content that is well-sized for large desktop displays, but appears too small on mobile devices. However, when a user has tapped once, WebKit cannot tell if the user intends on tapping again to trigger a d
Building a more interoperable Web with Microsoft Edge
Over the past year the Microsoft Edge team has been hard at work on a new browser engine that will be better than ever at correctly, quickly, and reliably rendering the Web. As a user, your favorite web sites will just work, and as a web developer, you will find that Microsoft Edge should just work like other browsers, making it easier than ever to create a site that works everywhere. We’ve implem
V8 JavaScript engine
