This was included in the 2010 Republican Pledge to America as "A requirement that Congress post all bills online three days before a vote." But it wasn't a bill nor even a rule change. It was just a promise about how they would do business. They dropped it before the 2012 election.
This followed a 2009 proposal to make a rule, as reported by Citizens Against Government Waste:
Rep. Greg Walden (R-Ore.) filed a discharge petition to force a vote on H. Res. 554, a bipartisan-backed bill that would require all non-emergency legislation to be posted online in its final form 72 hours before a vote.
H. Res. 554. In the Senate, it was S. Res. 307 and S. 1772.
Note: this does not preclude there being other initiatives before or after these. E.g. H. Res. 330 and H. Res. 230.
