项目需求: 字体在固定宽度的盒子中适应
知识点: css 、js

html结构:

 	<div class="logo">
        <div class="logo-name">
           {
   
   { logoObj.name }}
        </div>
    </div>

css代码:

		// 父级盒子
      .logo {
    
    
        float: left;
        width: 200px;
        height: 52px;
        line-height: 52px;
        color: #fff;
        text-align: center;
        cursor: pointer;
        overflow: hidden;
        // 文字样式
        &-name {
    
    
          font-family: PangMenZhengDao;
          height: 52px;
          line-height: 52px;
          text-align: center;
          font-size: 26px;
          font-weight: bold;
          display: inline-block;
          white-space: nowrap;
          transform-origin: left center;
        }
      }

js逻辑处理:

    handleTextAdaptive() {
    
    
      let domContainer = document.querySelector('.logo');
      let domText = domContainer.querySelector('.logo-name');
      if (domText.clientWidth <= domContainer.clientWidth) {
    
    
        domText.style.transform = 'none';
      } else {
    
    
        let r = domContainer.clientWidth / domText.clientWidth;
        domText.style.transform = 'scale(' + r + ')';
      }
    },
