Using icons in buttons

Icons can be used inside other components, like buttons. For demos of how to use icons inside buttons, see the Button documentation.

Icon sizes

Icons support a few different pre-defined size options. Right now the supported sizes are: medium, small, and x-small.

If no size property is provided, the medium size will be used by default.

Icon size examples for all supported size values.
Example icon at medium sizeMedium Icon20px
Example icon at small sizeSmall Icon16px
Example icon at extra-small sizeExtra-small Icon12px


x-small icon size is only intended for use in certain special cases. Most components should use Icons in small or medium size.

CSS-only version

You can use icons in a no-JavaScript context via a the CSS icon Less mixin provided by the Codex library. To use this mixin, import the mixin file and apply .cdx-mixin-css-icon() to an empty <span> element. The parameters of the mixin are as follows:

Param nameDescriptionDefault
@param-icon (required)The icon to use, in the form of a Less variable. These variables are also provided by the mixin file. The syntax for the Less variable version of an icon name is @cdx-icon-icon-name, e.g. @cdx-icon-info-filled. See the list of all icons for icon names.
@param-fill-colorThe hex code of the fill color of the icon@color-base
@param-size-iconThe icon size@size-icon-medium
@param-is-button-iconWhether the icon is inside of a <button> elementfalse


Before importing the css-icon mixin, you must first import the design tokens. If you don't, you will get errors that look like variable @color-base is undefined.


Visit the Button docs for details on using CSS icons within buttons.

Icon color

Use the second parameter of the .cdx-mixin-css-icon() mixin, @param-fill-color, to apply a hex code as the SVG fill color.


Icon sizes

Use the third parameter of the .cdx-mixin-css-icon() mixin, @param-size-icon, to use one of the pre-defined size options (@size-icon-medium, @size-icon-small, or @size-icon-x-small).

The CSS icon mixin supports icons that differ between the left-to-right (LTR) and right-to-left (RTL) reading directions. To take advantage of this behavior, in RTL contexts, one of the following is required:

  • A dir="rtl" attribute set on the <html> element.
  • A dir="rtl" attribute set directly on the icon span.


In RTL contexts, ensure that a dir="rtl" attribute is set either on the <html> element or on the icon element itself.
