- a. specific variable names in the application
- b. specific types of JavaFX nodes
- c. values that the user enters
- d. named constants in the application
When a selector name begins with a period in a JavaFX CSS style definition, the selector corresponds to “specific types of JavaFX nodes”.
Hence, the correct answer is option “B”.
Explanation of Solution
Type Selector Names:
- The selector names, which are starting with a period is type selector.
- Type selector is corresponding to a particular type of JavaFX nodes.
- These names are identical to the JavaFX class names to which they correspond.
- For example
- If the class name is “Button” then the corresponding type selector is “.button”.
- If the class name is “CheckBox”, then the corresponding type selector is “.check-box”.
Explanation for incorrect options:
a. specific variable names in the application:
It is not a valid one and it is not corresponds to specific names in the JavaFX CSS style definition.
Hence, the option “A” is wrong.
c. values that the user enters:
It is not a valid one and it is not corresponds to user entered values in JavaFX CSS style definition.
Hence, the option “C” is wrong.
d. named constants in the application:
It is not a valid one and it is not corresponds to named constant in JavaFX CSS style definition.
Hence, the option “D” is wrong.
