I am currently developing a web application using node-webkit, which is based on Google's Chrome browser. I have encountered an issue when embedding a PDF file on the site using the embed tag - there is a white line at the top of the embedded part (see attached picture). Initially, I thought it might be a border, but setting border = 0 did not solve the problem. My theory is that this white line is actually part of the background of the embed area and Adobe's PDF plugin does not cover the entire embed area.
Edit
If my hypothesis holds true, it would already be helpful if I could change the background color of the embed area to a different color. However, setting background-color has not worked either.
