  - write your classes using the sep 
      <element class:class1;class2;class3={condition} />
      Custom sep
      <element class:class1@class2@class3={condition} />
  - two separators for toggle 
      <element class:true-class1;true-class2;;false-class1;false-class2={condition} />
      Custom sep 
      <element class:true-class1@true-class2@@false-class1@false-class2={condition} />

<label class:text-gray-500,bg-gray-50,border-gray-300="{isValid}">text</label>

<!-- OR -->

<label class:text-gray-500|bg-gray-50|border-gray-300="{isValid}">text</label>
