Add a with the text as the closest sibling to the element, which conveys the exact information as the icon. When an icon gives the user some information, whether inbuilt as an indicator or in a block of text, that information can be made available to screen-readers. It uses the icon in place of text inside of a large message. It conveys some information, such as a status. The parent or must be direct text content, aria-label or meaningful label provided by aria-label. The element must be a child of the or element. Symbols alone are not interactive elements for screen-reader users. In interactive icon, a user will click or interact with the icon to perform some action. When an icon is cosmetic and conveys no real semantic meaning, the element is marked with aria-hidden="true". It has no real semantic meaning and it is purely cosmetic. In accessibility, there are three categories: The user of should provide additional information about the use of the icon. AccessibilityĪn icon alone does not provide any useful information for the screen-reader user such as the element. It can be changed to 'Primary,' 'Pronunciation' or 'Warning'. The color is changed to match the colors of the current theme using the color attribute. Icons uses the current font color (currentColor). Many icon sets also can registered in the same namespace. To display icons from the icon set, use SVG icon input in the same way as for registered icons. Each nested tags is identified with an ID attribute. This is done by creating a single root tag that contains some nested tags in its section. Icon sets allow many icons to be grouped into a single SVG file. But in a non-default namespace, use the format. Use the name directly in default namespace. Use the AddSvgIconLiteralInNamespace methods of AddSvgIcon, addSvgIconInNamespace, addSvgIconLiteral or MatSconRegistry to associate an icon with an icon URL. To avoid XSS vulnerabilities, any SVG URL and HTML strings passed in MatIconRegistry must be marked as trusted using the Angular's DomSanitizer service. The SVG icon has the same color as the surrounding text and allows to change the color by setting the color style on the matte-icon element. The default color of SVG content is the CSS currentColor value. This approach provides an advantage over the tag or CSS background-image as it allows SVG to be styled with CSS. displays the SVG icon by inserting SVG content into the DOM as its own child. You can specify the default font class to be used when the font set is not explicitly set by saying tDefaultFontSetClass for both types of font icons. If we want to use such font, set the font input to the font's CSS class and set the font icon input for the class to show the specific icon. By default, expects the content icon font.įonts can also display icons by defining a CSS class for each icon graph, which precedes the selector icon. To use the ligature icon, insert text into the content of the matte-icon component. Some fonts are designed to display icons using ligature by presenting the text as a as a home image. If an empty string is provided, the icon will be hidden from the accessibility layer with aria-hidden = "true." If there is no alt on the icon on the parent element, a warning will pop up on the console. If there is no Ari-label on the icon nor the label on the parent element, a warning will be logged on the console. The icon will be hidden from the access layer with aria-hidden = "true" if an empty string is provided. To use the icon set, developers pre-register the set using the $ mdIconProvider service. Specific set names can be used with the syntax. The string name is used to search for icons from the internal cache Projected strings or expressions can also be used here. The String URL (or expression) is used to load, cache, and display any external SVG. This value can also be used to look for a classname Use $ mdIconProvider.fontSet to determine the style name. The CSS style name is associated with the font library specified as a class for the font-icon. It requires the fonts and named CSS styles to be loaded. The CSS icon's string is associated with the font-face, which is used to render the icon. The following table lists the parameters and descriptions of different features of md-icon. It also supports icon fonts and SVG icons in addition to using Google content icons. An Angular Material icon is a component for showing vector-based icons in applications.
