Can anyone help me with how to get the style like in the image attached below using background colour for a div? I tried adding using pseudo-classes before and after but doesn't seem to be coming through.
.card {
height: 190px;
background: #070B32;
width: 360px;
position: relative;
}
.card:before {
background: #070B32;
position: absolute;
content: "";
left: 0;
height: 50px;
border-radius: 50% 50% 0 0;
}
.card:after {
background: #070B32;
position: absolute;
content: "";
right: 0;
height: 50px;
border-radius: 50% 50% 0 0;
}
<div class="card">
</div>

Answer 1

Use width top values too to have semi-circles with a change in color
.card {
height: 190px;
background: #070B32;
width: 360px;
position: relative;
}
.card:before {
background: white;
position: absolute;
content: "";
left: 0;
top:35%;
width: 25px;
height: 50px;
border-radius: 0 150px 150px 0;
}
.card:after {
background: white;
position: absolute;
content: "";
right: 0;
top:35%;
width: 25px;
height: 50px;
border-radius: 150px 0 0 150px;
}
<div class="card">
</div>
Update:
div {
height: 150px;
margin: 5em 2em;
background: radial-gradient(circle at left center, transparent, transparent 30px, #070B32 30px, transparent), radial-gradient(circle at right center, transparent, transparent 30px, #070B32 30px, transparent);
border-radius: 8px;
position: relative;
width: 360px;
margin: auto;
}
body {
background-image: url(http://www.fillmurray.com/1000/1000);
background-size: cover;
}
<div>
</div>

Answer 2

you should use width: 50px, background-color: white;
and responsive vertical alignment:
top: 50%; transform: translateY(-50%);
.card {
height: 190px;
background: #070B32;
width: 360px;
position: relative;
}
.card:before {
background: #ffffff;
position: absolute;
content: "";
left: -25px;
top: 50%;
transform: translateY(-50%);
height: 50px;
width: 50px;
border-radius: 50%;
}
.card:after {
background: #ffffff;
position: absolute;
content: "";
right: -25px;
top: 50%;
transform: translateY(-50%);
height: 50px;
width: 50px;
border-radius: 50%;
}
<div class="card">
</div>

Answer 3

Or just use a background.
.card {
--circle-color: #fff;
--circle-size: 50px;
background: radial-gradient(farthest-side circle, var(--circle-color) 97%, transparent) calc(100% + (var(--circle-size) / 2)) 50% / var(--circle-size) var(--circle-size),
radial-gradient(farthest-side circle, var(--circle-color) 97%, transparent) calc(var(--circle-size) / -2) 50% / var(--circle-size) var(--circle-size),
#070B32;
background-repeat: no-repeat;
height: 190px;
width: 360px;
}
<div class="card">
</div>
