Get dash-dot and dash-dot-dot border using CS [duplicate] - css

Question

How to created dash dot and dash dot dot lines and rectangles like
in CSS without using external links to images or other (inline data urls can used if there is no better way).
https://codepen.io/ibrahimjabbari/pen/ozinB
contains some samples like
hr.style17:after {
content: '§';
display: inline-block;
position: relative;
top: -14px;
padding: 0 10px;
background: #f0f0f0;
color: #8c8b8b;
font-size: 18px;
-webkit-transform: rotate(60deg);
-moz-transform: rotate(60deg);
transform: rotate(60deg);
}
. It uses content and rotate CSS properties, maybe those can used.

You can try a combination of repeating-linear-gradient and radial-gradient
.dash-dot {
height:50px;
background:
radial-gradient(circle at center,#000 2px,transparent 3px) 5px 50%/20px 5px repeat-x,
repeating-linear-gradient(to right,#000,#000 10px,transparent 10px,transparent 20px) center/100% 3px no-repeat
}
.dash-dot-dot {
height:50px;
background:
radial-gradient(circle at center,#000 2px,transparent 3px) 0px 50%/30px 5px repeat-x,
radial-gradient(circle at center,#000 2px,transparent 3px) 10px 50%/30px 5px repeat-x,
repeating-linear-gradient(to right,#000,#000 10px,transparent 10px,transparent 30px) center/100% 3px no-repeat;
}
<div class="dash-dot"></div>
<div class="dash-dot-dot"></div>
To have a rectangle you need to repeat the same on each side:
.dash-dot {
height:210px;
background:
/*right*/
repeating-linear-gradient(to bottom,#000,#000 10px,transparent 10px,transparent 20px) calc(100% - 1px) 0/3px 100% no-repeat,
radial-gradient(circle at center,#000 2px,transparent 3px) 100% 5px/5px 20px repeat-y,
/*left*/
repeating-linear-gradient(to bottom,#000,#000 10px,transparent 10px,transparent 20px) 1px 0/3px 100% no-repeat,
radial-gradient(circle at center,#000 2px,transparent 3px) 0 5px/5px 20px repeat-y,
/*top*/
repeating-linear-gradient(to right,#000,#000 10px,transparent 10px,transparent 20px) 0 1px/100% 3px no-repeat,
radial-gradient(circle at center,#000 2px,transparent 3px) 5px 0/20px 5px repeat-x,
/*bottom*/
repeating-linear-gradient(to right,#000,#000 10px,transparent 10px,transparent 20px) 0 calc(100% - 1px)/100% 3px no-repeat,
radial-gradient(circle at center,#000 2px,transparent 3px) 5px 100%/20px 5px repeat-x;
}
<div class="dash-dot"></div>
