this is my reference/inspiration
I have a motorcycle shop website an I found this very creative menu for a bike shop online. I was planning on implementing it in my motorcycle website but I don’t know where to start. For now I am using Django, html, css, and planning on using JavaScript.
try this code
.half-circle {
width: 200px;
height: 100px;
background-color: gold;
border-top-left-radius: 100px;
border-top-right-radius: 100px;
border: 10px solid gray;
border-bottom: 0;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}<div class="half-circle"></div>
