  Any particular reason to use CSS triangles over Unicode arrow characters?
  • tonfa 14y ago
    It works even if the font doesn't support all unicode characters.

      Also nerd cred.

  I think it would be incorrect to use css to create an interactive object, a page should be 100% usable without css. And probably font rendering is a lot faster than css rendering, though I couldn't find a similar benchmark

    "Interactive object" in question is just a link. It would work without CSS just fine. But it would not work without JavaScript (in current implementation). As for rendering efficiency: it just does not matter. There is a lot of things that could be improved on HN that would have orders of magnitude larger impact on performance.

  Doesn't work in IE7, at least not the last time I needed to draw variably sized triangles on a page.
