CSS for icons

Iconify API can dynamically generate CSS for icons, where icons are used as background or mask image.

This allows rendering icons with a simple <span> tag without any components.

Query

API URI that generates CSS is /{prefix}.css?icons={icons}, where:

  • "{prefix}" is icon set prefix. To generate CSS for icons from multiple icon sets, send separate queries for each icon set.
  • "{icons}" is list of icon names, separated by comma.

Examples:

.icon--openmoji {
   display: inline-block;
   width: 1em;
   height: 1em;
   background: no-repeat center / 100%;
}

.icon--openmoji--axe {

Using icons in HTML is easy: use a placeholder element with 2 class names: class name for an icon set and class name for icon:

<span class="icon--openmoji icon--openmoji--axe"></span>
<span class="icon--mdi icon--mdi--account"></span>

Why 2 classes? This allows splitting common style in separate rule, reducing duplication and making it easier to target all icons from an icon set.

If you want to reference icons with 1 simple class, you can use selector and common options. See examples below.

Options

Optional parameters:

  • download. If set to "true" or "1", sends CSS as an attachment, forcing browser to download file.
  • iconSelector or selector. Selector for icon, defaults to ".icon--{prefix}--{name}". Variable "{prefix}" is replaced with icon set prefix, "{name}" with icon name.
  • commonSelector or common. Common selector for icons, defaults to ".icon--{prefix}". Set it to empty to disable common code (see one of examples below). Variable "{prefix}" is replaced with icon set prefix.
  • overrideSelector or override. Selector that mixes iconSelector and commonSelector to generate icon specific style that overrides common style. See below. Default value is ".icon--{prefix}.icon--{prefix}--{name}".
  • pseudoSelector or pseudo, boolean. Set it to true if selector for icon is a pseudo-selector, such as ".icon--{prefix}--{name}::after".
  • varName or var. Name for variable to use for icon, defaults to "svg" for monotone icons, null for icons with palette. Set to null to disable.
  • forceSquare or square, boolean. Forces icon to have width of 1em.
  • color. Sets color for monotone icons. Also renders icons as background images.
  • mode: "mask" or "background". Forces icon to render as mask image or background image. If not set, mode will be detected from icon content: icons that contain currentColor will be rendered as mask image, other icons as background image.
  • format. Stylesheet formatting option. Matches options used in Sass. Supported values: "expanded", "compact", "compressed".

Other optional parameters are the same as in getIconsCSS() function of Iconify Utils.

Color and mode

There are two types of icons:

  • Monotone icons, which use currentColor for color.
  • Icons with hardcoded palette, where colors cannot be changed.

Monotone icons are rendered as mask image with background color set to currentColor. That means icon will use same color as text.

To change icon color, simply change text color:

<span class="icon--mdi icon--mdi--home" style="color: gray"></span>

Result:

Monotone icon used as mask: (hover to see color change)

Icons with palette used as background:

Icons with hardcoded palette are rendered as background image.

You can force background or mask mode by adding mode parameter: &mode=background or &mode=mask

You can also use color parameter to convert monotone icons to icons with palette: &color=green.

CSS variables

Important note about color option: you cannot use CSS variables. Color is not added to style, it is changed inside icon. Icon is not inlined in HTML, it is treated as an external resource. Elements of icon cannot be targetted or styled, just like any other image linked with url(), therefore CSS variables are not available in icon.

If you want to use a CSS variable for color, do not use color option, add color to icon in your stylesheet or inline style by changing text color:

<span class="icon--mdi icon--mdi--home" style="color: var(--icon-color)"></span>

More examples

You can customise generated stylesheet using various optional parameters.

Getting CSS for one icon with custom selector by adding selector parameter:
