"Customize the appearance of your theme by adjusting the background and text colors when making a

Is there a way to dynamically change the style of a webpage based on user selection using CSS in AngularJS?

I've searched online, but haven't found a solution that works for me.

I have a CSS file with different styles and I want to apply these styles to various divs by changing background color, text color, and font style as needed.

    $scope.model.webPageSkin = 'Default';  

    // create a list of themes  
    $scope.bootstraps = [  
        { name: 'Plain', url: 'Plain' },  
        { name: 'Blue', url: 'Blue' },  
        { name: 'Green', url: 'Green' } , 
        { name: 'Default', url: 'default' } , 
    ]; 

**Plain.css**

.ChangeColor  
{  
    font-family: "Source Sans Pro",Calibri,Candara,Arial,sans-serif;  
    font-size: 15px;  
    line-height: 1.42857143;  
    color: #333333;  
    background-color: #ddd;  
}  


**default.css**

.ChangeColor  
{  
    font-family: "Source Sans Pro",Calibri,Candara,Arial,sans-serif;  
    font-size: 15px;  
    line-height: 1.42857143;  
    color: #333333;  
    background-color: #3c8dbc;  
}  

<div class="wrapper>
     <header class="main-header">
          <nav class="navbar navbar-static-top" ng-class="{ChangeColor: 
           model.webPageSkin !important;}">
          </nav>
     </header>

<div class="row">
<select  ng-model="model.webPageSkin" ng-options="bootstrap.url as bootstrap.name for bootstrap in bootstraps">  
                </select>
</div>
</div>

Any suggestions on how to achieve this dynamic style switching are welcome!

Answer 1

Answer №1

When using ng-class in AngularJS, it is important to remember that it evaluates an expression, not the CSS styling you may be trying to apply.

Check out the ngClass API documentation

To correctly use ng-class, make sure your markup specifies that you want the 'ChangeColor' css class applied when the model.webPageSkin evaluates to true.

ng-class="{'ChangeColor': model.webPageSkin}">

Answer №2

If you want to modify your code, try the following approach:

ng-class="{'ModifyStyle': model.pageSkin==='Standard'}">

The ng-class directive is effective with conditions that result in either true or false. When the condition evaluates to true, the specified class will be applied.
