This was a vote to pass H.R. 2331 in the House. This vote was taken under a House procedure called “suspension of the rules” which is typically used to pass non-controversial bills. Votes under suspension require a 2/3rds majority. A failed vote under suspension can be taken again.
H.R. 2331 requires all federal agencies that create or update a website intended for use by the public to ensure that the website is mobile friendly. A mobile friendly website is defined as a webpage easily navigated on a smartphone, tablet, or similar mobile device.
