Our CSS Flexbox generator lets you create a layout, and skip knowing the confusing properties and value names (let's be honest the W3C did not make a good job here). Not gonna lie, this was heavily inspired by flexer.dev but coded completely from scratch.* ### Behavior change for External ResourcesAdding External Resources will no longer create a list of resources in the sidebar but will be injected as a **LINK** or **SCRIPT** tag inside of the HTML panel.* ### Code Completion with additional contextThe Code Completion will now also have the context of all panels before suggesting code to you - so if for example youhave some CSS or JS, the HTML panel will suggest code based on the other two panels.Introducing some AI sprinkle in the editor - Code Completion based on the **Codestral** model (by **Mistral**).For now it's a BYOK implmentation which means you need to provide your own API Key − you **can get it for free**.* ### Editor switch from CodeMirror to Monaco (same as VSCode)After much deliberation I've decided to make the switch from **CodeMirror to Monaco**.There's a few reasons for this. CodeMirror 5 is no longer being developed, and the switch to 6 would be a hugerewrite since there's not much compatibility between the two versions.Monaco itself has lots of features already built-in, things that took quite a few external plugins to getinto the CodeMirror implementation.**I'm incredibly thankful to Marijn for his work on CodeMirror**, it has served well for many years.Technical debt is a drag man. Remember the time when **MooTools** was state-of-art JS framework? We do and so much of JSFiddle was still dependant on it till this day, but since almost all MooTools features are nowavailable in native JS it was high-time to strip it out of the codebase.This took around a week of work, lots of testing, but it's now done.
