PURE CSS DONUT CHART

All right, let us now get into the steps of building a simple donut chart using HTML and CSS only.

 

PART 1) PIE CHART

1A) THE HTML

donut-chart.html
<!-- (A) DONUT CHART -->
<div class="donut"></div>

A <div class="dnout"> is all the HTML we need to get started.

 

1B) THE CSS

donut-chart.css
/* (A) PIE CHART */
.donut {
  /* (A1) CIRCLE */
  width: 300px; height: 300px;
  border-radius: 50%;
 
  /* (A2) SEGMENTS */
  background: conic-gradient(
    red 0deg 80deg,
    green 80deg 190deg,
    blue 190deg 360deg
  );
}

  • (A1) Use width: 300px height: 300px to create a square, and add border-radius: 50% to turn it into a circle.
  • (A2) Next, we specify the segments using conic-gradient. As you already know, a full circle is 360 degrees. So we just specify the segments using COLOR START-DEGREE END-DEGREE.

Yes, I know. This is a pie and not a donut. Have some patience, we will get into that in the next step.

 

 

PART B) DONUT CHART

2A) THE HTML

donut-chart.html
<!-- (A) DONUT CHART -->
<div class="donut"><div class="hole"></div></div>

How does one convert a pie into a donut? Punch a <div class="hole"> in the middle.

 

2B) THE CSS

donut-chart.css
/* (B) DONUT "CONVERSION" */
/* (B1) SMALLER CIRCLE */
.hole {
  width: 180px; height: 180px;
  border-radius: 50%;
  background: #fff;
}
 
/* (B2) "CONVERT PIE TO DONUT" - CENTER SMALLER CIRCLE */
.donut {
  display: flex;
  align-items: center;
  justify-content: center;
}

  • (B1) That’s right. We create a smaller circle within the pie chart.
  • (B2) Then using CSS flex, we center this smaller circle in the middle of the pie chart – This effectively “converts” the pie chart into a donut chart.

 

 

PART C) THE LEGEND

3A) THE HTML

donut-chart.html
<!-- (B) LEGEND -->
<div class="legend">
  <div class="segment1"></div> <div>First</div>
  <div class="segment2"></div> <div>Second</div>
  <div class="segment3"></div> <div>Third</div>
</div>

Some other tutorials on the Internet do some “not-so-simple calculations” to put the labels/segments directly in the chart itself… I figured that is “too confusing”, and the easiest way is to create a separate legend.

 

3B) THE CSS

donut-chart.css
/* (C) LEGEND */
/* (C1) LEGEND CONTAINER */
.legend {
  display: flex;
  margin-top: 30px;
}
 
/* (C2) SEGMENTS */
.legend div { padding: 0 10px; }
.segment1 { background: red; }
.segment2 { background: green; }
.segment3 { background: blue; }

Lastly, there is not much of a mystery here. The legend is just a simple “flexbox legend bar”.

 

 

USEFUL BITS & LINKS

That’s all for the tutorial, and here is a small section on some extras and links that may be useful to you.

 

NOT GREAT FOR COMPLEX DONUTS

Of course, we can build simple donut charts using pure HTML and CSS. But when it comes to a complex multiple segments chart, it quickly becomes extremely painful with manual calculations and placements. So a little bit of Javascript to “automate” the calculation will do great – I shall leave that as a possible future update.

 

COMPATIBILITY CHECKS

CSS flex and conic gradient are well-supported on all modern “Grade A” browsers.

  1. Hi, this is so helpful thank u a lot!

    I just would love to place the text in the middle of the hole.
    Is there any possibility to do this?

    1. Directly enter the text inside <div class="hole">.

      Set both donut and hole to centered flex – B2 .donut, .hole { ... }

  2. Worked perfectly and satisfied my needs without requiring JavaScript. I’ve converted this into a Blazor component and can now use it whenever I need it. Thanks!
