How Can I Create Transparent Cutout Circles Using Only CSS?

Creating Transparent Cutout Circles with CSS

In CSS, drawing solid circles is a ubiquitous task. However, cutting out a hollow circle poses a unique challenge. Can this be achieved using CSS alone?

Exploring the Possibilities

We can easily create a filled circle using CSS, but achieving transparency and a hollow interior requires a bit more ingenuity.

Answer: Two Ingenious Techniques

There are two primary approaches for creating transparent cutout circles in CSS:

1. Leveraging SVG (Scalable Vector Graphics)

SVG allows us to define shapes using XML-based markup. By utilizing the mask element, we can cut out a transparent area and create a hollow circle:

<svg viewbox="0 0 100 50" width="100%">
  <defs>
    <mask>

2. Employing a Path Element

Alternatively, we can create a hollow circle using a path element that defines two arcs:

<svg width="100%" height="50">
  <path d="M 50,25 A 15,15 0 1 1 50,25 L 50,40 A 15,15 0 1 1 50,25" stroke="none" fill="#000000" fill-opacity="0.7" />
</svg>
