Browsers apply extraneous spaces when letter-spacing #319

Open xfq opened 4 years ago

xfq commented 4 years ago

This issue applies to all languages that use letter-spacing.

Currently browsers that apply letter-spacing do so by adding a space after every letter in the text that is tracked. This results in a superfluous space at the end of the range, which creates an inappropriate gap before the following text. Letter spacing at the end of a line makes the line look misaligned in justified or right-justified text. It also has implications for text that has other styling, such as an outline or a coloured background, at the same time as being stretched.

For more details, see this GitHub issue, which is being used to track this gap. Please add any discussion there, and not to this issue.

I think it has already been discussed at the CSSWG Virtual F2F. See https://github.com/w3c/csswg-drafts/issues/1518#issuecomment-665354152
