Description of problem

I have a code and everything, but when I try to add the image for a background nothing pops up, it just remains black. I'm wondering what the issue is, I can provide the code I am using as well.

Code:

.postprofile {
            border-radius: 4px;
            border: 2px solid black;
            background-image: url(https://i.postimg.cc/ZRKmKLqp/Profile-plate.png);
        }

Code:

.postprofile {
       border-radius: 4px;
       border: 2px solid black;
       background-image: url(https://i.postimg.cc/ZRKmKLqp/Profile-plate.png)!important;
 }

Thankyou, it works now; i will mark this as solved

You're welcome.
