Here is an arrow with pure CSS. Supported by all browsers.

.arrow {
  width: 120px;
}

.line {
  margin-top: 14px;
  width: 90px;
  background: blue;
  height: 10px;
  float: left;
}

.point {
  width: 0;
  height: 0;
  border-top: 20px solid transparent;
  border-bottom: 20px solid transparent;
  border-left: 30px solid blue;
  float: right;
}

<div >
  <div ></div>
  <div ></div>
</div>

As already mentioned, you can do it with pseudo-elements. Here's a way to do it:

<!DOCTYPE html>
<html lang="en">

    <head>
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <style>
            .parent {
                display: inline-flex;
                flex-direction: column;
                width: 100%;
                margin-bottom: 10px;

            }

            .children {
                position: relative;

            }

            .children {
                margin-left: 12px;
            }

            .parent .children:not(:last-of-type):before {
                content: "";
                width: 1px;
                height: 100%;
                background-color: #666;
                top: 0;
                left: -10px;
                position: absolute;
            }

            .parent .children:last-of-type:before {
                content: "";
                width: 6px;
                height: 10px;
                border-left: 1px solid #666;
                border-bottom: 1px solid #666;
                border-radius: 0 0 0 6px;
                top: 0;
                left: -10px;
                position: absolute;
                font-size: 10px;
                line-height: 19px;
            }

            .parent .children:last-of-type:after {
                content: "";
                width: 4px;
                height: 0px;
                border-top: 5px solid transparent;
                border-bottom: 5px solid transparent;
                border-left: 5px solid #666;
                top: 5px;
                left: -6px;
                position: absolute;
            }
        </style>
    </head>

    <body>
        <div >
            Parent
            <div >child</div>
            <div >child</div>
