How can I make the image occupy the entire container? My idea is to be as shown in the photo. Being the red frame the image and the black frame rounded the container of images
#article{
background-color: rgb(126,230,222, 0);
padding: 0;
height: 70%;
width: 55%;
margin: 0 auto;
border-radius: 20px 20px 20px 20px;
box-shadow: rgba(0,0,0,0.8) 0 0 10px;
}
<div id="article">
<div id="slider">

<img id="imgSlider" src="https://static.pexels.com/photos/207962/pexels-photo-207962.jpeg"/>
