no-repeat failure

• Problem background: The scss language is used to write the background picture, and the picture disappears. The following code:

background-image:url(../images/close.png) no-repeat;  

• Cause of the problem: In the case of background-image, only the url attribute can be added, and other attributes cannot be added;
• Solution: Remove the image limit to increase the range of modified attributes

background:url(../images/close.png)  no-repeat;
