So what are you waiting for? Say no to legacy baggage and start saying yes to HTML5 and the future by adding the GCF header/tag to your sites and apps. It’s nearly zero effort. When you’re comfortable, you can add a prompt and free yourself to build sites and apps against only the modern web. When you do, you’ll see how fast and productive web development can really be. I promise you won’t want to go back. Thanks to GCF, you won’t have to.
