Microsoft Edge Developer

Hi, are you a web developer or designer?

“No, I just want to share feedback on Microsoft Edge.”

Please use the Feedback Hub (requires Windows 10) to submit your feedback in the Microsoft Edge category. This site is for web developer and designer feedback only. Other feedback will be closed without action.

“Yes, I’m a web developer or designer with feedback for the Microsoft Edge platform.”

Great! This site is where the Microsoft Edge team collects feature requests from the web developer and designer community in the categories listed to the right. For bugs on existing features, please log an issue on the Issue Tracker.

Your feedback will help us with planning and to better understand how web developers and designers are using the platform. Top standards-based feature requests will also be copied over to status.microsoftedge.com, where you can track its development status.

For the most actionable feedback, please search and up vote for existing suggestions before submitting a new suggestion, and create a separate suggestion per idea. Note that off topic or inappropriate suggestions may be moderated. The Microsoft Edge team will use suggestions as an important input, but there are several additional factors that inform the final roadmap.

A note from our lawyers: Please do not send any novel or patentable ideas, copyrighted materials, samples or demos which you do not want to grant a license to Microsoft. See the Terms of Service for more information.

How can we improve the Microsoft Edge developer experience?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

        • :has()

          https://drafts.csswg.org/selectors/#relational

          The relational pseudo-class, ‘:has()#’, is a functional pseudo-class taking a relative selector list as an argument. It represents an element if any of the relative selectors, when absolutized and evaluated with the element as the :scope elements, would match at least one element.

            • Implement conic gradients from CSS Image Values Level 4

              Conic gradients [1] are useful for a number of effects on the Web that cannot be emulated in any other way (see [2]). They can be implemented in many graphics libraries today (e.g. Cairo) via mesh gradients. Please implement them.

              • Update CSS Scroll Snap Points

                Now that both Firefox 39+ and Safari 9 supports it in addition to being in development in Chrome, updating the Scroll Snap Points implementation to match the current spec is crucial. The current implementation from the IE 10 days is outdated and incompatible with the changes made since then.

                Why hasn't there been any talk regarding this, and why hasn't it been done already?

                Spec: https://drafts.csswg.org/css-snappoints/

                • CSS attr() as defined in CSS Values Level 3

                  Allows attr() to be used in any CSS rule (not just generated content), any CSS property (not just content) and for various data types.

                  Spec: http://www.w3.org/TR/css3-values/#attr-notation

                  This will revolutionize what we can do with CSS and enable a kind of decoupling between content and styling that has never been possible before.

                  • Support SVG 2 paint-order property

                    The SVG 2 paint-order property allows authors to control the order in which stroke, markers, and fill are painted for each shape, or for text. This can be used to create outlines that do not obscure fine details of shapes or text. It can also be used to create more subtle line markers that do not obscure the line itself.

                    The basic fill/stroke/markers options, as defined in the current draft of the specification, are already supported in Firefox, Chromium, and Webkit. They are therefore unlikely to change, although additional options may be added by future specifications.

                    http://www.w3.org/TR/SVG2/painting.html#PaintOrder

                    • image-rendering: pixelated

                      This declaration is used to preserve pixels when scaling up images (e.g. pixel art). IE provides this functionality via -ms-interpolation-mode: nearest-neighbor. The other browser engines also provide this functionality (see here: http://www.simevidas.com/2015/05/10/Blowing-up-pixel-art-on-the-Web.html).

                      • Support CSS Motion Path Module

                        Since SMIL will be deprecated in Blink and there is no intent to implement in MS Edge, we need to fill in the gaps and provide alternative ways to do with CSS what we could do in SMIL.

                        The CSS Motion Path spec is now a Level 1 module and is in W3C Working Draft status:: http://www.w3.org/TR/2015/WD-motion-1-20150409/

                        Using the properties defined in this specification, we will be able to animate HTML and SVG elements along arbitrary paths, using nothing but good old CSS.

                        There is a bug report open to fixes in Blink, hopefully to make it to implementation this…

                        • Support calc() in Flexbox rules

                          Please just axe IE and don't rebrand with the Spartan project. You're literally the worst browser in every conceivable test http://html5test.com http://css3test.com and yet you make fun of people who critique you instead of dumping resources into fixing your garbage browser. https://www.youtube.com/watch?v=lD9FAOPBiDk

                          So happy Chrome is bashing you nowadays. You deserve it.

                                      This feature would add support for the <dialog> element to create in-page modal windows.

                                      • all:initial

                                        Supported by Firefox and Chrome and gives the developer more control over CSS cascading. This would be helpful when when writing components that get inserted in other environments.

                                        Preferably both property: initial and all: initial would be supported.

                                        • tab-size property

                                          CSS3 tab-size is supported in all other browsers, and defines how many spaces the tab character should consist of.
