htmlcssxmlprocessing-instruction

Is there a CSS selector matching processing instructions?

I'm having a HTML document that contains processing instructions and should be styled using CSS. I didn't find any way to refer to the processing instructions from CSS. Is this possible?

<div>
  Hello World
  <?pi1 ?>
  Test
  <?pi2 ?>
</div>
Solution

  • No. Browsers will treat them as bogus comments, so in the DOM they will be comment nodes. CSS selectors match element nodes, so the processing instructions are not referable.
