<li style="background-image: url(../../assets/images/indexbg1.png);"></li>
li{
width: 258px;
height: 100px;
background-size: 100%;
}
this code should be okay, right? But the picture (development environment) cannot be displayed
to prove that the picture path is correct, I used the img tag and tried again
<img src="../../assets/images/indexbg1.png"> //
so it"s strange here, why can img display pictures, but not background images? And it"s the same picture path.
