It appears in cloud platforms like Google Cloud where provisioning Cloud SQL databases, or in data pipeline tools like Apache Airflow where defining data source connections requires universally recognized database symbols.

Question 3

What does the Circle Stack Solid icon tell users?

It's drawn in currentColor, so it takes the text color wherever you use it. To bake a color in, set one in Customize before you copy.

Question 12

How do I change the size of the Circle Stack Solid icon?

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Question 13

How do I make the Circle Stack Solid icon accessible?

Accepted Answer

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Circle Stack Solid", so screen readers say what it does.
