Jumbotron parallax issue

Hi there,

Firstly, incredible theme - thank you so much for taking the time to create it and distribute it for free. The site I am currently using it on is www.saltirecontracting.com.

My question is with regards to the jumbotron. Initially I was having issues with its display on mobile devices (It would crop massively into the image on anything other than a desktop making it unusable). However, I used the css below to remedy the situation.

@media only screen and (max-width: 2732px) {
#header {
background-attachment: initial !important;

I now have a beautiful jumbotron image on desktop, ipad & iphone. However, on desktops it now no longer has the parallax effect. Delete this code and it returns but so to does the ugly appearance on mobile. I’m happy with the trade but after going through every post in the forum to fix the original mobile display problem I figured some people might be interested in this development so thought id flag it up.

Thanks again & all the best.
