<span class="split-content">Lorem ipsum</span>
<button type="button" class="btn btn-primary btn-sm">Button</button>
</div>
</div>
</div>
</div>
But i have a small bug, in the after element i see some blue backround line from the first div. It looks like a border line genrated from the radius. But i wannt a clean white round background.

Answer 1

Put border: 2px solid white in :after.
Here is css code:
body {
text-align: center;
}
.split-outer {
position: relative;
display: inline-block;
width: 200px;
height: 200px;
z-index: 2;
background: #014495;
border-radius: 100%;
}
.split-outer::after {
content: "";
position: absolute;
left: -2px;
bottom: -1px;
width: 100%;
height: 50%;
z-index: -1;
background: #fff;
border-bottom-right-radius: 200px;
border-bottom-left-radius: 200px;
border: 2px solid white;
}
.split-inner {
width: 200px;
height: 200px;
margin: 0 auto;
color: #fff;
text-align: center;
}
span {
display: block;
}
span.split-title {
padding: 30px 0 10px 0;
font-size: 55px;
text-align: center;
line-height: 55px;
}
span.split-content {
padding: 20px 0;
font-size: 18px;
color: #014495;
}

You could create the top half of the background by removing the background color from .split-outer and then using a :before pseudo, similar to how the bottom half is created with an :after pseudo.
.split-outer:before {
content: "";
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 50%;
z-index: -1;
background: #014495;
background-image: initial;
background-position-x: initial;
background-position-y: initial;
background-size: initial;
background-repeat-x: initial;
background-repeat-y: initial;
background-attachment: initial;
background-origin: initial;
background-clip: initial;
background-color: #014495;
border-top-right-radius: 200px;
border-top-left-radius: 200px;
}
