I am trying to add a background image to my html by using the background
property but it's showing invalid in my browser. I looked for the error and found this question with same problem. Still not able to figure out the problem.
Here is my code of css:
#showcase {
background: url("../img/showcase.jpg") no-repeat top center fixed/cover;
position: relative;
min-height: 650px;
color: #fff;
padding-top: 6rem; }
