Built for the Modern Web Trix supports all evergreen, self-updating desktop and mobile browsers. This gives Trix complete control over what happens after every keystroke, and avoids the need to use execCommand at all. Trix sidesteps these inconsistencies by treating contenteditable as an I/O device: when input makes its way to the editor, Trix converts that input into an editing operation on its internal document model, then re-renders that document back into the editor. Most WYSIWYG editors are wrappers around HTML’s contenteditable and execCommand APIs, designed by Microsoft to support live editing of web pages in Internet Explorer 5.5, and eventually reverse-engineered and copied by other browsers.īecause these APIs were never fully specified or documented, and because WYSIWYG HTML editors are enormous in scope, each browser’s implementation has its own set of bugs and quirks, and JavaScript developers are left to resolve the inconsistencies. See Trix in action in the all-new Basecamp 3. Millions of people trust their text to Basecamp, and we built Trix to give them the best possible editing experience.
