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.

        • Implement the display: contents

          When using layout modes like flexbox and grid, there is a conflict between the desire to keep the DOM tree relatively flat, to avoid complex, unperformant, highly-nested layouts, and grouping elements in a way that makes sense semantically and allows easy manipulation via data-binding frameworks like Angular.

          This conflict can be solved by supporting the "display: contents" box-generation mode from CSS Display Module Level 3. This allows elements to be configured to generate no box of their own, only those of their children. In this way, complex, nested DOM structures can generate much simpler box trees.

          • Implement :focus-within from Selectors 4

            Tons of UIs include elements that are not visible unless the user interacts with their parent or ancestor. Think popup menus, delete or edit buttons, floating formatting toolbars, copy buttons, editing popups and so on. The list is endless. This is a good way to reduce visual clutter.
            However, this is often done in an inaccessible way, just by using :hover, because making it accessible requires JS, since :focus does not apply to ancestors. However, 1 in 2 people writing HTML/CSS are not comfortable with JavaScript so keyboard accessibility (and usability, as many of us are keyboard users by choice)…

                  • :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.

                      • 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.

                        • CSS Intrinsic Sizing

                          Extends the CSS sizing properties with keywords that represent content-based "intrinsic" sizes and context-based "extrinsic" sizes, allowing CSS to more easily describe boxes that fit their content or fit into a particular layout context.

                                  • Bring `gap` property to flexbox

                                    As outlined in the linked issue, having the ability to use grid-gap on flexbox (which is soon to be renamed just "gap" by the CSS Working Group because "grid-gap" doesn't make sense when used on flexbox) solves a major pain point that developers are facing.

                                    See the issue for more details:

                                      • CSS property "list-style: none" is ignored in MS Edge

                                        even when `list-style` is set to `none` for lists MS Edge stil rendering the list bullets. Looks like `list-style: none` is completely ignored by MS Edge
