the .mdx file didn’t include the .css file so the format information wasn’t applied to the .mdx. I added a line for each entry:
<link rel=“stylesheet” type=“text/css” href=“DWDS - artikel.css”>
so that the .css file can be applied.
As for the links, they were originally redirected to the DWDS website, so I changed it to make it connected the entries in this .mdx file.
