Can you please take a look at the background video on this website? http://www.agilest.org/home/
The background video does not scale down well for screen sizes less than 1280px. The video stops covering the entire screen width once the screen width gets below 1280px.
Perhaps, this little snippet of code does not seem like a big deal to you, but it means a lot! You guys have the best support I have encountered in this field! Thank you very much.
This did the trick:
.fl-row-bg-video .fl-bg-video video {
max-width: none;
}
