How can I ensure that carousel pictures are displayed clearly within the box without overflowing? The code I tried resulted in the pictures overflowing from the box and not being visible clearly. How can I resolve this issue?
.container {
width: 1490px;
height: 645px;
margin: 0;
padding: 0;
background: rgba(0,0,0,0.4);
position: absolute;
margin-top: 40px;
}
.sub-container {
width: 1000px;
height: 350px;
margin-left: 280px;
background-color: red;
overflow: auto;
}<div class="container">
<div class="sub-container">
