CSS开发技巧

1. 布局边界显示
   新建书签，在网址栏输入以下代码，保存书签，在想要查看样式的页面点击书签，会切换显示布局

javascript: (function(){ var style = document.querySelector('#_outline_'); if (style) { style.parentNode.removeChild(style); } else { style = document.createElement('style'); style.id = '_outline_'; style.innerHTML = "*{outline: 1px solid red}"; document.body.appendChild(style); } })();

2. 单行文本省略号

width:200px;//固定宽度
overflow:hidden;
text-overflow:ellipsis;
white-space:nowrap;

3. 超出两行文本省略号

width:200px;//固定宽度
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 2;
overflow: hidden;

4. 去除数字输入框默认样式

width:200px;//固定宽度
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 2;
overflow: hidden;

5. 优化checkbox框
   

// HTML
<svg class="checkbox-symbol">
      <symbol id="check" viewbox="0 0 12 10">
        <polyline
          points="1.5 6 4.5 9 10.5 1"
          stroke-linecap="round"
          stroke-linejoin="round"
          stroke-width="2"
        ></polyline>
      </symbol>
    </svg>

    <div class="checkbox-container">
      <input class="checkbox-input" id="apples" type="checkbox" />
      <label class="checkbox" for="apples">
        <span>
          <svg width="12px" height="10px">
            <use xlink:href="#check"></use>
          </svg>
        </span>
        <span>Apples</span>
      </label>
      <input class="checkbox-input" id="oranges" type="checkbox" />
      <label class="checkbox" for="oranges">
        <span>
          <svg width="12px" height="10px">
            <use xlink:href="#check"></use>
          </svg>
        </span>
        <span>Oranges</span>
      </label>
    </div>
// CSS

      }

      .checkbox span {

        transform: scale(1);
        border: 1px solid #cccfdb;
        transition: all 0.3s ease;
      }

      .checkbox span:first-child svg {
