You can inject your own stylesheet to customize styles however you want.

new EmbedBox({
  embedCode: "<script src='http://embedbox.io/examples/library.js'></script>",
  name: "Example Stylesheet App",
  style: "" +
  ".header .title {" +
  "  color: hotpink;" +
  "  text-shadow: 0 0 4px pink;" +
  "}"
})
