I'd like to know how to do to make the False ng-class.
page.isSelected(1) is TRUE if the page if the page is selected, else FALSE
<div id="homePage" ng-class="{ center: page.isSelected(1) }"> I therefore want you if:
isSelected is TRUE: center
isSelected is FALSE: left
I tried:
<div id="homePage" ng-class="{ page.isSelected(1) 'center : 'left' }"> but it doesnt work.
I do not know what I'm doing wrong. Can you help me please?

To add a conditional class in Angular we can pass an object to ngClass where key is the class name and value is condition i.e., true or false as shown below. And in the above code, class name will be added only when the condition is true.
yes , you can do it. Did you try it? What happened? You can use both class and ngClass as the first one gives you the opportunity to apply a class that you want to implement in all cases under any circumstances and the later to apply classes conditionally.
AngularJS ng-class Directive The ng-class directive dynamically binds one or more CSS classes to an HTML element. The value of the ng-class directive can be a string, an object, or an array. If it is a string, it should contain one or more, space-separated class names.

Just make a rule for each case:
<div id="homePage" ng-class="{ 'center': page.isSelected(1) , 'left': !page.isSelected(1) }"> Or use the ternary operator:
<div id="homePage" ng-class="page.isSelected(1) ? 'center' : 'left'"> You can use the ternary operator notation:
<div id="homePage" ng-class="page.isSelected(1)? 'center' : 'left'"> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
