Correct answer
Explanation
In Apache Flex, the alpha property controls the transparency (opacity) of a visual component, ranging from 0.0 (completely transparent) to 1.0 (fully opaque). Setting alpha affects how much of what's behind the component shows through - it does not affect brightness, spacing, or dimensions. This is a fundamental visual property in Flex UI components.
AI explanation
The alpha (opacity) property controls how transparent or opaque an element is; increasing it makes the element more solid/visible, decreasing it makes it more see-through. It has nothing to do with brightness, spacing, or dimensions, which are controlled by separate properties.
