W3C has unveiled the official HTML5 logo, which is available under “Creative Commons 3.0 By” so it can be adapted by designers to meet their needs.
You can also use this badge builder to create your own customized logo.
It stands strong and true, resilient and universal as the markup you write. It shines as bright and as bold as the forward-thinking, dedicated web developers you are. It’s the standard’s standard, a pennant for progress. And it certainly doesn’t use tables for layout.
And flash as well! 😀
“The logo’s silhouette is that of a badge, implying both the formality and respect an undertaking of this magnitude demands, but also as a homage to the progressive community that proudly, and relentlessly, ushers in the future of web technologies. Simultaneously a badge of honor and a coat of arms, this crest represents the spirit and substance of the open web platform and the forward-thinking community making it a reality”
Why orange? Orange is a very hot, fast, and striking color, but not nearly as intimidating or aggressive as red. Orange implies excitement, yet with undertones of caution. Orange grabs your attention, but doesn’t scream for it. In Chinese color theory, orange is the color of organization. In medieval heraldry, orange was symbolic of strength and endurance. Sexy with a safety net, organized, powerful and lasting. HTML5, this logo, and orange go quite well together.[source]
