.content-block.video svg.icon { display: none; } .media-embed-wrapper { width: 100%; max-width: 1024px; } .media-embed-wrapper .media-embed-code { max-height: none; } .media-embed-wrapper .media-embed-code iframe { aspect-ratio: 16 / 9; height: 100%; } The above css fixes youtube's (and presumably other video embed - not tested) height on spectrum. To use this you'll need something like stylish: firefox https://addons.mozilla.org/en-US/firefox/addon/styl-us/ chrome https://chromewebstore.google.com/detail/stylus/clngdbkpkpeebahjckkjfobafhncgmne Whilst we're on the subject of using stylish to "fix" things, should you fancy removing the top navigation bar on spectrum too, use the following [data-rsi-component=PlatformBar] { display: none !Important }
