  • WebKit Fix: Quirk News.Y Combinator to Skip TextAutoSizing
    Looking at the html of HN's pages, can't blame them really. Running though https://validator.w3.org/ , the result is abysmal. At this rate, if web browsers started requiring sites to output HTML that is somewhere in the realm of normalcy, HN would sooner shut down than consider ever updating. - Source: Hacker News / 7 days ago
