# Styling RSS w XLS notes XML files can include both xml-stylesheets (XSLT) and normal stylesheets (CSS). XSLT files are transformations, and allow you to process an XML doc into an HTML doc (among other things). In this case, it doesn't matter if we import the CSS here or via /rss/rss.xsl -- it gets applied either way. The XSLT will output HTML for us, but the HTML content from the RSS feed (i.e., the bodies of posts) must be unescaped. There's a special attribute (`disable-output-escaping`) which will do that. However, we need to run some JS, too, because not every browser supports decoding html like that. * firefox does not seem to support `disable-output-escaping="yes"`, so it requires the JS in rss.js * chrome does support `disable-output-escaping="yes"`, so don't remove those attrs The JS works by testing `#cometestme`, and then (if needed) looping over elements matching `[name=decodable]` and basically `el.innerHTML = el.textContent`. Note, `disable-output-escaping="yes"` is a legacy feature from XSLT v1.0; the new way to do it is with character maps. When I tried those, they didn't seem to work in firefox (which is when I tried the original JS). IDK if chrome support character maps, but if it does, then that is a good update to implement. TODO I guess. <p>this script will speed up (or slow down) video and audio via ffmpeg.</p> <p>put the following in e.g., <code>~/.local/bin/mod-video-speed</code> and <code>chmod +x</code> it.</p> <div
