Notes

  • 1

    Partial. Not supported inside the <body>.

  • 2

    Partial. Not supported with Non Gmail Accounts.

  • 3

    Buggy. The first <head> in the HTML is removed, so <style> elements need to be in a second <head> element.

  • 4

    Buggy. <style> elements need to be declared before their rules are used.
