css shapes - How to code an arrow using css

Question

Hi guys I'm trying to code an arrow like this in css, I'e viewed examples on codepen, but now I'm thinking whether it is actually possible?

Answer 1

Here is another trick using only one element and multiple linear-gradient as background and you can adjust the size/position of each arrow individually:

.arrows {
  width:300px;
  height:100px;
  position:relative;
  background:
  /* For the 3 lines*/
  linear-gradient(#000,#000) 10px 25px/2px calc(100% - 30px),
  linear-gradient(#000,#000) 50% 0/2px calc(100% - 2px),
  linear-gradient(#000,#000) calc(100% - 10px) 25px/2px calc(100% - 30px),
  /*for the arrows*/
  linear-gradient(to top left,transparent 50%,#000 0%) 10px 100%/10px 10px,
  linear-gradient(to top right,transparent 50%,#000 0%) 0px 100%/10px 10px,
  
  linear-gradient(to top left,transparent 50%,#000 0%) calc(50% + 5px) 100%/10px 10px,
  linear-gradient(to top right,transparent 50%,#000 0%) calc(50% - 5px) 100%/10px 10px,
  
  linear-gradient(to top left,transparent 50%,#000 0%) 100% 100%/10px 10px,
  linear-gradient(to top right,transparent 50%,#000 0%) calc(100% - 10px) 100%/10px 10px;
  background-repeat:no-repeat;
}
.arrows:before {
  content:"";
  position:absolute;
  top:20px;
  left:10px;
  right:10px;
  height:8px;
  border:2px solid;
  border-bottom:none;
  border-radius:10px 10px 0 0;
  box-sizing:border-box;
}

<div class="arrows"></div>
