> https://drafts.csswg.org/css-text-4/#text-spacing-property > > This proposal was found in the following issue: > > * [[css-text-4] Text-spacing is too strict #3229](https://github.com/w3c/csswg-drafts/issues/3229) > > > 1. In the above description of `ideographic-alpha` and `ideographic-numeric`, change "Creates 1/4em extra spacing between" to "Creates extra spacing between." > > and this issue was resolved as: > > > RESOLVED: Add a new text-spacing:auto value, which is not the initial value. > > I am ok with adding the `auto` value, but I think it's not sufficient. Changing "Creates 1/4em extra spacing between" to "Creates extra spacing between" is still necessary. > > The "1/4em extra spacing" is not the best choice in many cases, and narrower space such as 1/6em is preferred. Apple iOS seems to use 1/6em for ideographic-alpha/numeric spacing. > > For the `auto` value, UA can choose such better spacing value for ideographic-alpha/numeric spacing, but stylesheet authors cannot use the `auto` value when they need to choose specific text-spacing style, e.g., preference between `allow-end` and `trim-end`, or `space-first` and `trim-start`. So the spacing value of `ideographic-alpha` and `ideographic-numeric` should be same as the spacing value for ideographic-alpha/numeric spacing with `auto`. > > FYI, [Vivliostyle](https://vivliostyle.org/) supports the `text-spacing` property, with `auto` value which is equivalent to `trim-start trim-end trim-adjacent ideograph-alpha ideograph-numeric` and the `ideograph-alpha` and `ideograph-numeric` create 1/6em space.
