Vue implements star rating with decimal points

<style>
 main{
  position:relative;
  }
 .star_line{
  /* Set to force no line break */
  width-space:nowrap;
  overflow: hidden;
  position: absolute;
  }
 .star{
  display: inline-block;
  /* Set the mouse to turn into a small hand style when it is placed on a star*/
  cursor: pointer
  }
</style>

<div id="app">
 <input type="text" v-model.number="score">
 <- When any component receives the bound value in a two-way binding, it must use value to receive it. The principle is as follows: input ->
 <v-star v-model="score"></v-star>
</div>
