Answer 1

您可以定义高度，

.portfolioImg{
  height:400px; 
}

您可以将图像宽度和高度属性设置为100％，

img{
 width:100%;
 height:100%
}

Answer 2

试试这个

.portfolioImg img { 
   width:100%; 
}

Answer 3

.portfolioImg {
background:url('../imagepath/imagename') center center no-repeat;
background-size:cover;
height:100vh; or height:manual
}

Answer 4

在css属性下面申请：

.portfolioImg img{
    max-width: 100%;
    width: auto;
}
