Go to the site, go to the CSS category, choose any property and look at the Result section (if available).
You can also see if you inspect the example there is only a tag and an empty body tag.

It looks like when DevDocs scrapes MDN's content, their scraper filters out hidden elements.
Looking at a typical CSS document at MDN's GitHub repository, its Example and Try It sections are stored as fenced code blocks in its markdown source. However, only one type of section appears in the DevDocs version.
The Try It sections don't get deleted with this filter, and they appear undifferentiated in the final document.

However, the Example sections do get deleted, because there's these
hiddentags as part of each code block.https://github.com/mdn/content/blob/e522944060c9b7b17c1a9f373ecf4503b8d14445/files/en-us/web/css/filter-function/blur/index.md?plain=1#L102-L106
(I really wish these code blocks embedded...)
Plus, I'm not sure if I can find any code that would actually take these code blocks, unescape them, and run them in a sandboxed <iframe>. It'd probably be relatively easy once we'd get to that point, considering how permissive HTML5's parser is.

Hi,
Is this issue still open? I’d like to work on it if possible.
