     <div class="container-fluid">
       <div class="row">
         <div class="col-2 col-lg-3 ua-border-right-theme-blue ua-flex-full-align ua-h-65-px">

               <a class="ua-text-size-12 ua-text-color-theme-blue">{{$moment(item.createdAt).format('DD.MM.YYYY') }}</a>
             </div>

               <a class="d-block d-lg-none d-xl-block ua-text-size-12 ua-text-color-dark">{{item.title.length >= 50 ? `${item.title.substring(0, 50)}...` : item.title}}</a>
               <a class="d-none d-lg-block d-xl-none ua-text-size-12 ua-text-color-dark">{{item.title.length >= 40 ? `${item.title.substring(0, 38)}...` : item.title}}</a>

  transition: transform .3s cubic-bezier(1.0, 0.5, 0.8, 1.0), color .5s cubic-bezier(1.0, 0.5, 0.8, 1.0);
}

.fade-leave-active {
