How do CSS blobs work without SVG?

CSS blobs use the 8-value border-radius property syntax (horizontal-radii / vertical-radii) to create asymmetric, curved organic shapes purely in CSS.

Can I download the shape as a scalable vector graphic (SVG)?

Yes, you can copy the raw SVG vector markup or download the shape as a standalone .svg file.
