    padding: 80px 0px;
    display: flex;
    flex-wrap: wrap;
    justify-content: space-around; 
  }
  .progress-outer {
    width: 60%; height: 12px;
    border-radius: 8px;
    overflow: hidden;
    position: relative; 
  }    
  .progress-enter {  
    height: inherit;
    background: rgba(180, 160, 120, .2); 
  }
  .progress-bg {
    width: 60%; height: inherit;
    border-radius: 6px; 
    background: repeating-linear-gradient(-45deg, #D9CFBB  25%, #C3B393 0, #C3B393 50%,

    }
  }
</style>
<template>
