SVG Circles in HTML

Here's a quick tutorial that will teach you how to create a circle with HTML's svg and circle tags.

SVG circle

<svg xmlns=""
viewBox="0 0 1000 200">

<circle cx="500" cy="100" r="75"
opacity="1.0" />

The Attributes

Here are the attributes used to define our circle:

  • cx & cy: The x and y coordinates of the center of the circle.
  • r: The radius of the circle, relative to the site of the viewbox.
  • stroke: The color of the border line. This value can be defined either by specifying a hexadecimal color code as we did above or by using a valid color name.
  • stroke-width: The width of the border line output to the screen, relative to the size of the viewbox.
  • fill: The fill color can also be defined as a hexadecimal color code or color name and will fill the circle with the color specified. Specifying a value of none will keep the circle fill color transparent.
  • opacity: Determines if the circle will have any transparency. Valid decimal values can be between 0.0 (invisible) and 1.0 (fully visible). A value of 0.5 would give the circle 50% transparency.
