Conditional classes

Conditional classes have been possible for a very long time in Angular with the ngClass syntax. There are several different ways to use it.

First version


Second version

// single
[ngClass] = "{'css-class': true}"

// multiple same condition
[ngClass] = "{'css-class css-class2': true}"

// multiple different conditions
[ngClass] = "{'css-class': true, 'css-class2': false }";

Third version

[ngClass] = "(true)?'css-class1':'css-class2'";
