Customization

INFO

Check everything about the customization mechanics in the "How it works" documentation.

CSS Variable	Type	Description
--z-smiling-z--fill	color	Fill color
--z-smiling-z--size	distance	Size of the Smiling Z

Both the color and the size of the z-smiling-z can be customized using the --z-smiling-z--fill and --z-smiling-z--size CSS custom properties respectively.

Extending isotype or modifying sources

We can use the --z-smiling-z--urlCSS variable to change the source of the icon. This way, we can use any SVG file as an icon. The rest of the component will behave the same.

The custom-str won't work with this prop, so we need to use the CSS or using style or custom for instances.

SVGs for icons must be flattened

The SVG file must be flattened to work correctly. This means that the SVG file should not have any nested SVG elements or multiple SVG sub-elements.

It's better and more comfortable to do this override anyway in a CSS general file:

[z-smiling-z] {
  --z-smiling-z--url: url(https://upload.wikimedia.org/wikipedia/commons/3/3b/Eo_circle_green_checkmark.svg);
}

We can also use this approach to extend the icon catalog with custom icons.

[z-smiling-z][data-brand="react"] {
  --z-smiling-z--url: url(https://upload.wikimedia.org/wikipedia/commons/a/a7/React-icon.svg);
}
