I'm facing an issue with the image in the masthead of a Bootstrap Template. I tried to change the image URL to my desired picture in the CSS file of the downloaded Bootstrap files, but even after saving it, the image on the page remains the same old one that I deleted. Interestingly, when I add the new URL in the CSS file using Chrome's Dev Tools, the preview displays exactly what I want. However, implementing the same changes in my actual code within the C9 workspace doesn't reflect any updates, and Bootstrap continues to use the old default image despite me removing it completely from the Workspace. If anyone can help pinpoint where I might be going wrong, I would greatly appreciate it.
The Bootstrap CSS
header.masthead{position:relative;background-color:#343a40;background:url(../img/bg-masthead.jpg) no-repeat center center;}
I am trying to change it to
header.masthead{position:relative;background-color:#343a40;background:url(http://www.4usky.com/data/out/94/164852092-the-riddler-wallpapers.jpg) no-repeat center center;}
