A structural directive that conditionally includes a template based on the value of an expression coerced to Boolean.

The default template for the else clause is blank.

An attribute directive that updates styles for the containing HTML element. Sets one or more style properties, specified as colon-separated key-value pairs. The key is a style name, with an optional .<unit> suffix (such as 'top.px', 'font-style.em'). The value is an expression to be evaluated. The resulting non-null value, expressed in the given unit, is assigned to the given style property. If the result of evaluation is null, the corresponding style is removed.

A structural directive that adds or removes templates (displaying or hiding views) when the next match expression matches the switch expression.

Provides a switch case expression to match against an enclosing ngSwitch expression. When the expressions match, the given NgSwitchCase template is rendered. If multiple match expressions match the switch expression value, all of them are displayed.
