css background image not working

1background-image: url(../picture-folder/your-picture.png) 0 0; 
2//No quotes, two dots before "/"
3//Also make sure that your <img> in html has some transparent image as src

1.container {
2    background-image: url("img/rose.jpg");
3 	height: 800px;
4}
5/* Check Path to image, in this case, its in a folder called img */
6/* Check if you Linked your css File on your header, you Link it in the 
7	Header like this <link rel="stylesheet" href="main.css"> */
8/* Check if the Name of your Image is the same like how you saved it */

1background-image: url(nickcage.jpg); // No quotes around the file name so just write it down without "nickcage".jpg

1body { background: url('image_path_name') repeat 0 0; }

3Make sure image_path_name is correctly written, if not then kindly check file extension once.

1background-image: url(nickcage.jpg); // first problem may be missing quotation mark
2// Second may be wrong path 
3// check the name of the file if there is any error
4// check whether you are using proper extension of the file
