文字

使用图像替换类交换背景图像的文本。

利用.text-hide类或mixin帮助用背景图像替换元素的文本内容。

<h1 class="text-hide">Custom heading</h1>
// Usage as a mixin.heading {
  @include text-hide;}

使用.text-hide该类来维护标题标签的可访问性和搜索引擎优化的好处,但希望利用background-image而不是文本。

<h1 class="text-hide" style="background-image: url('/assets/brand/bootstrap-solid.svg'); width: 50px; height: 50px;">Bootstrap</h1>
