eliminate the border line of iframe

[laiyenju]

The original iframe style may display frame border. I add an argument border: 0 to fix the problem. Make the iframe looks cleaner.

Here is the effect I tried on my Jekyll blog: https://laiyenju.github.io/datanews-0

Thank you for your suggestion, actually the existing integration guide on Jekyll does not meet the standard iframe integration, which states in this guide. Do you mind to follow 2nd and 3rd steps of the guide and update for Jekyll accordingly?
