Use Vue.js class bindings to create blank spaces in between CSS classes

I'm utilizing a v-bind:class binding on a component in order to toggle a css class based on the truthiness of a boolean within my Vue.js component.

When I specify this in my template:

<aside v-bind:class="{'--opened': sidebarVisible}" class="sidebar" id="sidebar">

In the script section of my component:

<script>
import { EventBus } from "@/event-bus.ts";
    export default {
        data(){
            return {
                sidebarVisible: false
            }                
        }    
        //Removed for brevity            
};      

</script>

My expectation is that Vue.js will update the class attribute to class="sidebar--opened", however, it actually renders as class="sidebar --opened" with an empty space. How can I work around this issue?

Answer №1

To apply a separate class to this element, you must include the full name of the class like so:

<aside v-bind:class="{'sidebar--opened':sidebarVisible}" class="sidebar" id="sidebar">

Please note: If this method does not work, you may need to explicitly remove the 'sidebar' class.
