How to show (HTML, ...) code with syntax highlighting

I use “Editor Syntax Highlight Obsidian Plugin”.
I have this file named “HTML Grundgeruest.md”.

## 1 Beispiel


```htmlembedded
<!DOCTYPE html>
<html lang="de">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Titel</title>
  </head>
  <body>

  </body>
</html>

It worked fine for a few days. When I open it now in Obsidian (Win10), I get the following error message:

What have I done to resolve the problem?

  • At first I thought the error comes from german umlauts, which I changed form ü to ue.
  • Tried to update the plugins, no news.
  • I installed the latest obsidian again.
  • I also cannot change the color of my tags via Obsidian.obsidian\snippets\tag_pills.css, but I think, this is another problem.

Then I deleted this from the note:

<!DOCTYPE html>
<html lang="de">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Titel</title>
  </head>
  <body>

  </body>
</html>

And the problem was gone …

But how can I include such code snippets?

Finally, it works again (perhaps a side effect of other problems). This issue is solved.
