How to create a dotted line consisting of circles in css?-CodePudding

Example IMG It is necessary to create a discontinuous line consisting of circles with a diameter of 4px. And the distance between the circles should be 8px. I can't get the desired result in CSS, please help.

CodePudding user response：

radial-gradient can do it:

.line {
  height: 6px; /* diametre */
  background: 
    radial-gradient(circle closest-side, blue 90%, #0000) 
     0/14px 100%; /* 14px = 6px   8px */
}

<div ></div>

CodePudding user response：

we can use this CSS solution:

border-top: 4px dotted red;

advantages:
- with only one div
- and no complex code
- no repetition

#line {
  border-top: 4px dotted red;
}

<div id="line"></div>

One approach could be like:

CSS like this:

.dot {
  height: 8px;
  width: 8px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  margin: 4px
}

And the HTML body would be like:

<body>

<div #dots style="text-align:center">
  <span ></span>
  <span ></span>
  <span ></span>
  <span ></span>
</div>

</body>

Result:

<!DOCTYPE html>
<html>

<head>
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <style>
    .dot {
      height: 8px;
      width: 8px;
      background-color: #bbb;
      border-radius: 50%;
      display: inline-block;
    }
  </style>
</head>

<body>

  <div #dots style="text-align:center">
    <span ></span>
    <span ></span>
    <span ></span>
    <span ></span>
  </div>

</body>

</html>
