Background Image not showing up in jumbotron

Question

I do not know what the problem is. I made a style.css and used this as my code

.jumbotron {
    background-image:url(images/bikebg.jpg);
    margin-top:-20px
}

before putting the background in the images folder, it worked fine. But since I changed it, it will no longer work. The site is live here http://bikesite.web44.net/bikes.html

Answer 1

try this

   .jumbotron {
        background-image:url(../images/bikebg.jpg);
        margin-top:-20px
    }

Answer 2

your folder path was wrong

try

url(../images/bikebg.jpg);
