Notes

1. Only supports the *-start, and *-end values for margin, border and padding, not the inline/block type values as defined in the spec.

2. Like #1 but also supports *-before and *-end for *-block-start and *-block-end properties as well as start and end values for text-align

3. Does not support the margin-block, margin-inline, padding-block, padding-inline, or any of the inset shorthand properties. Supported in newer Chromium browsers behind the #enable-experimental-web-platform-features flag

4. Does not support the border-start-start-radius, border-start-end-radius, border-end-start-radius and border-end-end-radius property.

5. Does not support the border-start-start-radius, border-start-end-radius, border-end-start-radius and border-end-end-radius property.

^* Partial support with prefix.
