Microsoft, together with Apple, Google, Mozilla and other companies, announced the launch of Interop 2024, which will continue the initiative to improve browsers and ensure a consistent user experience across all platforms. Participants aim to achieve a result where each technology will work the same in every browser.
Whether using Edge, Firefox, Safari or Chrome, all sites must provide the same expected features and functionality across all supported operating systems, according to the initiative's goals.
Announced in 2021, Compat 2021 focused on cross-browser compatibility. In 2022, the companies launched Interop 2022 for browser compatibility to identify weaknesses in designs and make the web platform a more pleasant experience.
Microsoft, Google and other companies have jointly implemented numerous improvements to the web platform and are ready to continue their partnership in this direction.
Interop 2024 will focus on several areas including layouts, CSS architecture, HTML elements, and more. Microsoft points out that Compat and Interop have significantly reduced the number of browser inconsistencies when using flexboxes and grids, but differences still exist.
Interop 2024 participants decided to make layout one of the priority areas this year. The initiative will improve CSS nesting to ensure it works consistently across browsers, and the Popover API in HTML will allow developers to display content on top of other elements.
Beyond the major focus areas, Interop 2024 will improve accessibility, user properties, font size, pointer events, scrollbar style, text orientation, and more.
Each of the initiative participants has already published detailed reports describing what will be implemented during Interop 2024. You can check the scores of each of the major browsers in the project tests here.
