Advertisements


The md-icon, an Angular directive, is a component to show vector-based icons in application. It supports icon fonts and SVG icons also apart from using the Google Material Icons.

Attributes

The following table lists out the parameters and description of the different attributes of md-icon.

Sr.No Parameter & Description
1

* md-font-icon

This is the string name of CSS icon associated with the font-face, which will be used to render the icon. Requires the fonts and the named CSS styles to be preloaded.

2

* md-font-set

This is the CSS style name associated with the font library, which will be assigned as the class for the font-icon ligature. This value may also be an alias that is used to lookup the classname; internally use $mdIconProvider.fontSet(<alias>) to determine the style name.

3

* md-svg-src

This is the String URL (or expression) used to load, cache, and display an external SVG.

4

* md-svg-icon

This is the string name used for lookup of the icon from the internal cache; interpolated strings or expressions may also be used. Specific set names can be used with the syntax <set name>:<icon name>. To use icon sets, developers are required to pre-register the sets using the $mdIconProvider service.
