<template> <div class="circle"> <div v-for="item in 50" class="item" :style="{ transform: `rotate(${item * 3.6}deg)` }"></div> <div class="top"></div> </div> </template> <script lang="ts" setup> import { transform } from 'ol/proj' </script> <style lang="less"> .circle { position: relative; width: 86%; height: 86%; left: 7%; top: 7%; border-radius: 50%; .top { position: absolute; width: 100%; height: 100%; left: 5%; top: 5%; border-radius: 50%; background-color: rgba(255, 255, 255); } .item { width: 100%; height: 3px; background-color: rgba(255, 255, 255, 0.5); position: absolute; left: 0%; top: 50%; } } </style> 请将以上的class="item"的线条缩短,距离最外层盒子10px

可以在`.item`的样式中加上`margin: -1.5px 0 0 -1.5px;`，同时将`.circle`的`border-radius`属性改为`calc(50% - 10px)`，即可将线条缩短并距离最外层盒子10px，修改后的代码如下所示：

<template>
  <div class="circle">
    <div v-for="item in 50" class="item" :style="{ transform: `rotate(${item * 3.6}deg)` }"></div>
    <div class="top"></div>
  </div>
</template>

<style lang="less">
.circle {
  position: relative;
  width: 86%;
  height: 86%;
  left: 7%;
  top: 7%;
  border-radius: calc(50% - 10px);
  .top {
    position: absolute;
    width: 100%;
    height: 100%;
    left: 5%;
    top: 5%;
    border-radius: 50%;
    background-color: rgba(255, 255, 255);
  }
  .item {
    width: 100%;
    height: 3px;
    background-color: rgba(255, 255, 255, 0.5);
    position: absolute;
    left: 0%;
    top: 50%;
    margin: -1.5px 0 0 -1.5px;
  }
}
</style>
