Welcome! This repo is home to "explainers" and related documents originating from the Microsoft Edge team.
Explainers are documents focused on describing a user/ developer/ customer problem (at a high level) and exploring potential solutions. These documents are starting points for engaging in discussion with you and other members of the community. Explainers should address their stated problems in clear and easy to understand language. Proposed solutions should be easy to follow and not too deep in technical details. When you read an explainer, we hope the stated problem is compelling and you can form an opinion for whether the proposed solution would address the problem.
Please provide feedback
We are looking for feedback! Are the stated problems relevant to you? How have they impacted your experience? Do the proposed solutions seem reasonable? Do they follow good web principles? Would they solve a problem you currently have? (We love to hear that; tell us more about your scenario!) Do you have related use-cases we hadn't considered?
We appreciate you taking the time to offer feedback; it helps to improve the explainers, validate the problem and solutions they describe, and show evidence that there is potential momentum to move an idea to the next stage. We desire to see all our explainers make the journey to become cross-browser supported web standards.
Have a product bug?
If you're looking to file a product bug on Microsoft Edge and the bug is unique to Edge, please use the in-browser "Send Feedback" tool (Alt+Shift+i in Windows, or "..." > "Help and feedback"). If the bug reproduces in another Chromium-based browser, please file the issue upstream in the Chromium bug database. Thanks!
These are the proposals we are currently investigating in this repo. Use the links below to read the explainers, review the current issues, and file new issues specifically for the given explainer(s). We hope they will all "graduate" and begin their journey along the standards-track as they gain sufficient interest; each explainer has a "status of this document" section that indicates what standards venue they expect to go to next (if known). When they graduate, we move them into the Alumni section below.

Awesome! These explainers have moved on to bigger and better things! We've archived the original explainers here for posterity and updated their document status section to help you find where the latest discussions are happening. Please continue to participate and follow the links below to the current standards communities. Thanks for your continued interest!

When at first you don't succeed… don't give up! We're no longer pursuing the solutions described in these explainers at this time, but that doesn't mean the problem isn't worth solving. Have an idea for an alternate solution? We'd love to hear your feedback!
|Custom Dialog on Close||This design conflicted with the philosophy of keeping tab close as fast as possible. Work is ongoing to describe a way to meet the needs that this design aimed to address.||2020-03-25|
|Arbitrary Text Fragments||We are now directing our efforts into providing feedback on the similar proposal ScrollToTextFragment already being incubated in the W3C Web Incubator Community Group.||2019-10-31|
|Password Reveal||Rather than working on this HTML controls feature in isolation, we have rolled this effort into the larger Open UI project of the Web Incubator Community Group in an effort to provide a standardized set of form controls for the web, including password.||2019-06-17|
