Set page number 1 start

[mrchristian]

All formats need page one to be set as the title page. This is an issue where a front cover is included.

[MurakamiShinyu]

If we want the page counter starting with 0 for the very first page (front cover), we can reset the page counter in the stylesheet as follows:

@page :first {
  counter-reset: page -1;
}

and when we support @page :nth(1) (see vivliostyle/vivliostyle.js#667 (comment)), the page counter can be reset at any document in a publication.

[MurakamiShinyu]

Now, Vivliostyle.js v2.5.0 supports the :nth() page selector.

See #700 feat(core): Support the :nth() page selector

• In multi-document publications, the :nth(1) matches the first page of each document,
  but the :first matches only the first page of the first document.
  (see: First-page pseudo-class :first should work on each document in a multi-document publication? (→support :nth()) vivliostyle/vivliostyle.js#667 (comment) )

You can use @page :nth(1) { counter-reset: page; } to reset the page counter at each or a specific document in a web book.
