  • 3

    Partial. Only background-color values are supported.

  • 4

    Partial. Images URL must be between quotes.

  • 5

    Partial. Does not support multiple values. The entire property is removed if so.

  • 6

    Partial. Does not support the / value shorthand for background-size.

  • 7

    Partial and buggy. Removes the entire style attribute or <style> tag when a url() function with a valid image URL is present. See Gmail rolling out changes that strip CSS with background images and Gmail and background images.
