Image
I have tried making a semicircle using CSS but it won't be suitable for the design that I want. I have used 2 jumbotrons, one after the other. The semicircle should cover the area on both jumbotron as in the image(link mentioned above).
Any help is appreciated on how can I achieve this design.
HTML:
<div class="jumbotron">
<div class="container navheader">
<div class="social">
<i class="fa fa-facebook " aria-hidden="true"></i>
<i class="fa fa-google-plus " aria-hidden="true"></i>
<i class="fa fa-instagram " aria-hidden="true"></i>
</div>
<div class="contact-us">
<a href="">
<i class="fa fa-phone " aria-hidden="true">
<label class="icon-label">CALL 0417 949 773</label></i></a>
</div>
</div>
</div>
<div class="jumbotron other-color">
<div class="container navheader">
<div class="user-actions">
<button class="btn btn-link" data-toggle="modal" data-
target="#sign-in">
<i class="fa fa-lock" aria-hidden="true">
<label class="icon-label">SIGN IN</label>
</i>
</button>
<button class="btn btn-link" data-toggle="modal" data-
target="#sign-up">
<i class="fa fa-user " aria-hidden="true">
<label class="icon-label">CREATE AN ACCOUNT</label>
</i>
</button>
</div>
<div class="div-semicircle top"></div>
<div class="cart">
<a href=""><i class="fa fa-shopping-cart " aria-
hidden="true">
<label class="icon-label">2 ITEM(S)</label>
</i></a>
</div>
</div>
</div>
CSS:
<style>
/* Remove the navbar's default rounded borders and increase the bottom margin */
.navbar {
margin-bottom: 50px;
border-radius: 0;
}
/* Remove the jumbotron's default bottom margin */
.jumbotron {
margin-bottom: 0;
background-color: #5a9f33;
padding: 2em 1em;
}
.other-color {
margin-bottom; 0;
background-color: #67b63d;
padding: 2em 1em;
}
.navheader{
display: inline-block;
width: 100%;
}
.social, .user-actions{
float:left;
}
.contact-us, .cart{
float:right;
}
.sign-up{
background-color:#67b63d;
margin: 0 50px 50px;
padding:20px;
}
input{
padding:15px;
margin:20px;
width:85%;
}
.btn-sign{
background-color: #67b63d;
font-family: serif;
color: white;
border-radius: 30px;
font-size: 2em;
padding: 10px 50px;
margin: 20px auto;
display: block;
}
.title{
font-family: serif;
font-weight: 600;
color: #67b63d;
font-size: 3em;
margin-top:20px;
}
.div-semicircle {
background: #9e978e;
display: inline-block;
margin: 0 1em 1em 0;
}
.top,
.bottom {
height: 45px;
width: 90px;
}
.top {
border-top-left-radius: 90px ;
border-top-right-radius: 90px;
}
</style>
UPDATE:
Solution: In case anyone wants to know, refer to the sample by #bhv in the first comment for reference and tweak it as per your requirement.

Answer 1

first of all your posted code isn't of any help....still I'll try to give a procedure how you can achieve the linked image
create a div not with class .container
create 2 navs inside above created div
create a jumbotron below the navs inside the same div and contain it
in a div with class container
set margins as you need it between these 3 to bring them together
It is clearly visible that you dont need a semicircle..you need an ellipse use clip-path: ellipse(65px 30px at 125px 40px); someting like this to create it within same div then position it in a way you want to using css and give it highest z-index so that it renders as top-most layer.
prey that it works!! ;-)

Answer 2

you must use position:absolute to cover both jumbotron
add these lines of code to this class: .div-semicircle.
position: absolute;
top: 23%;
left: 40%;
