"Technologies and Browser Requirements This site uses a number of advanced (but open and standard) technologies, including HTML5, CSS, and JavaScript. To use this project properly, you will need a modern browser that supports these technologies. The latest versions of Chrome, Firefox, Opera, and Safari are the best choices. The Internet Explorer and Edge browsers for Windows do not fully support the technologies used in this project. Display of mathematical notation is handled by the open source MathJax project." I've tried the interactive examples also in Safari Technology Preview and Firefox Developer Edition and work ok. :)
