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.

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

            • 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.

                                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.

                                        • Add Support for Scrollbar Styling

                                          Add support for scrollbar styling, similar to the earlier properties supported in Internet Explorer (i.e. scrollbar-base-color, etc)
