I need to create an arrow with rounded corners, I implemented it through a border, but the border radius does not apply where necessary. 
I only get this, not all corners can round off ...
.prev { left: 0; display: block; content: ""; width: 32px; height: 32px; right: 0; border: 8px solid #4a275c; border-radius: 5px; border-top: none; border-right: none; -webkit-transform: rotate(45deg); -ms-transform: rotate(45deg); transform: rotate(45deg); } <div class="prev"></div>
:beforeand:after, poking around for a long time with a similar problem, but the solution is just that - Artem Gorlachev
