背景圖片填充div

 

html:
<div class=”contain-title”><div>

css:
(1)這種情況下圖片可以填充整個div，但背景色和原背景圖片不一致
background: url(../images/mall-bg.png) no-repeat center center fixed;
height: 11.5rem;
width: 100%;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
display: flex;
justify-content: space-around;
align-items: center;

（2）和背景圖片基本一致，但背景圖片在寬度上沒有填充整個div，左右兩邊有間距
background: url(../images/mall-bg.png);
background-size: 100%;
height: 9rem;

（3）背景圖片在寬度上填充整個div，且基本與原背景圖片效果一致
width: 100%;
display: flex;
justify-content: space-around;
align-items: center;
background: url(../images/mall-bg.png);
height: 9rem;
background-position: center;
background-size: 110% 100%;
