Icons and Symbols

Storybook Github

Astro includes a library of common Icons, Symbols, and Notification Symbols. Persistent use of these will help ensure users are presented with consistent and meaningful information across applications.

Each of these must be easily identifiable by users and also be immediately distinguishable from each other, eliminating confusion and mistakes.

Astro’s icons have been designed to utilize the Astro Status System.

Monitoring Icons must include a label, a title attribute in the HTML and a status indicator. When used in a light theme status indicators must also include a 1 pixel border around the status indicator set to rgba(0,0,0,0.5)

Astro Icon Classes

Monitoring Icons

An Icon Label provides the name of the item being represented. An Icon Label should not change.

An Icon Sub-Label provides additional information to the user and may be dynamic. Use Sub-Labels only as needed to avoid unnecessary distraction.

Percentage Monitoring Icons

Percentage Monitoring Icons depict a value between 0 and 100 as an arc and a numeric display. Ranges within the arc may be mapped to the standard Astro Status Colors. In this example the range containing 80% is mapped to Serious.
