Example 1:

const sampleBoolean = true

Use . to combine multiple classes
<div class:sample-class-1.sample-class-2.sample-class-3="{sampleBoolean}">Example</div>
WILL BE COMPILED TO
<div
    class:sample-class-1="{sampleBoolean}"
    class:sample-class-2="{sampleBoolean}"
    class:sample-class-3="{sampleBoolean}"
>
    Example
</div>
WILL BE COMPILED TO
<div class="sample-class-1 sample-class-2 sample-class-3">Example</div>

Example 2:

const sampleBoolean = true

Use ! infront of class to negate condition for that specific class
<div class:!sample-class-1.!sample-class-2.sample-class-3="{sampleBoolean}">Example</div>
WILL BE COMPILED TO
<div
    class:sample-class-1="{!sampleBoolean}"
    class:sample-class-2="{!sampleBoolean}"
    class:sample-class-3="{sampleBoolean}"
>
    Example
</div>
WILL BE COMPILED TO
<div class="sample-class-3">Example</div>
