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:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

  1. Support CSS Reflections

    Webkit offers the ability to create reflections using CSS:

    I would love to see this in Edge as it can add a nice effect to images.

    • Add CSS transforms on SVG elements

      I created a CSS-based grid system for my SVG sprite sheet using transforms, only to revert to transform attributes after it collapsed in IE9+.
      Please add support for CSS transformation in SVG.

      • @document (css conditional rule)

        The @document rule has long been implemented in Firefox, but the W3C deferred further discussions about @document to CSS4, thus not carving anything out in stone - yet.

        Please make a push for getting the @document rule recognized and implmented in Edge, or something that works a similar way.

        Thank you!

            • :scrolling psuedoclass

              Currently, JS has to be used to apply styles to a scrolled container. It would be fantastic to have a psuedoclass like :scrolling or :overflowing to apply specific styling, like correcting for the space taken up by a scrollbar or perhaps applying a fixer header automatically.

                  • Make CSS unit 'ch' consistent with other browsers

                    Currently, IE claims to support the 'ch' CSS unit (http://www.w3.org/TR/css3-values/#font-relative-lengths), but its implementation differs from other browsers' one. While other browsers consider '1ch' equal to the overall width of the character, including its side-bearings, IE seems to take into account only the width of the painted area, without side-bearings. This makes IE's implementation almost useless in practical tasks like http://lea.verou.me/2012/02/simpler-css-typing-animation-with-the-ch-unit/. Can the implementation of this unit be changed for the parity with other browsers, so we could use it interoperably?

                      • Unprefix and support all @viewport properties

                        CSS Device Adaption (http://dev.w3.org/csswg/css-device-adapt) is partially supported through the @-ms-viewport rule, however the width and height property are the only ones supported. It would be nice if the zoom and orientation properties were supported, too (in addition to the rest of the spec), so that we'd get a real replacement for the non-standard viewport <meta> tag.

                        • 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.

                                • Support PNG, GIF & SVG cursors and other cursor enhancements

                                  Add support for more formats than just the CUR and ANI file formats in the CSS cursor property. PNG, SVG and GIF support would be good.

                                  Also, consider supporting the zoom-in/out and grab/grabbing properties, in addition to updating the browser-specific cursors like no-drop, all-scroll, col/row-resize, alias, cell, copy and context-menu cursors, as they look small/jagged, old and weird on my high DPI screen.

                                      • font-size-adjust & other font properties

                                        Add support for the CSS3 property used for adjusting font sizes consistently across font families. Supported in Firefox since the beginning.

                                        And please consider some of these font-related properties, too, potentially making it easier to customize and implement fonts on the web:
                                        * font-variant (and its children properties)
                                        * font-synthesis
                                        * font-kerning
                                        * @font-feature-values
                                        * font-language-override

                                        • Custom filters (shaders)

                                          Filter effects are a way of processing an element’s rendering before it is displayed in the document.
