 Local usage
 --------------------
 
-Since unfortunately ESM modules are not working on `file:` protocol due to [CORS issues](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules#other_differences_between_modules_and_standard_scripts), there is a bundled [single-file version working locally](https://asn1js.eu/index-local.html). It doesn't work online (due to [CSP](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) restrictions about inline content) but can be saved locally and opened in a browser. ([known bug](https://github.com/lapo-luchini/asn1js/issues/89): dark mode is currently broken in this mode)

     <p>On the left of the page will be printed a tree representing the hierarchical structure, on the right side an hex dump will be shown. <br>
       Hovering on the tree highlights ancestry (the hovered node and all its ancestors get colored) and the position of the hovered node gets highlighted in the hex dump (with header and content in a different colors). <br>
       Clicking a node in the tree will hide its sub-nodes (collapsed nodes can be noticed because they will become <i>italic</i>).</p>
