if you want to apply separate css classes for same element with conditions in Vue js you can use the below given method it worked in my scenario   html    lt div class  Main  v-bind class    Sub  page     gt    in here  Main and Sub are two different class names for same div element  v-bind class directive is used to bind the sub class in here  page is the property we use to update the classes when it s value changed   js  data   page   true      here we can apply a condition if we needed  so  if the page property becomes true element will go with Main and Sub claases css styles  but if false only Main class css styles will be applied

Use the object syntax   v-bind class    fa-checkbox-marked   content  cravings      fa-checkbox-blank-outline    content  cravings       When the object gets more complicated  extract it into a method   v-bind class  getClass     methods       getClass            return                fa-checkbox-marked   this content  cravings                   fa-checkbox-blank-outline    this content  cravings              Finally  you could make this work for any content property like this   v-bind class  getClass  cravings     methods     getClass property       return          fa-checkbox-marked   this content property          fa-checkbox-blank-outline    this content property
