描述

https://drafts.csswg.org/cssom/#resolved-values

See https://github.com/w3c/csswg-drafts/issues/1346 for the spec issue around position: sticky, though note per the original discussion on the Chromium bug tracker position: fixed makes no more sense as currently spec'd.

http://output.jsbin.com/wunoxod/quiet is a simple test page.

Results:

position: static relative sticky absolute fixed

Firefox 53 auto 0px auto 224px 296px
Edge 14 auto auto n/a auto auto

研究方向
Review the CSSOM resolved values spec at https://drafts.csswg.org/cssom/#resolved values and the test page at http://output.jsbin.com/wunoxod/quiet. Look at existing tests in the wpt repository under css/cssom/ for patterns. The issue requires writing tests that verify the resolved values for position static, relative, sticky, absolute, and fixed across browsers, focusing on the discrepancies noted. No maintainer comments or linked PRs exist, so the solution should propose a new test file in the appropriate directory.
