html - mdl-stepper 不响应溢出

Question

我遇到的问题，您可以通过 codepen.io 查看就是无论我做什么，我都无法让 mdl-stepper 使其高度与里面的内容相同。

这似乎没有真正的 getmdl.io。

CSS(我知道这是问题所在)

Answer 1

HTML 更改

     /** remove inline css height and overflow it will enable scroll **/
     <ul class="mdl-stepper mdl-stepper--linear mdl-stepper--horizontal"  style="display:inline-block;"id="ipet-stepper">
      <li class="mdl-step mdl-step--editable">
        <span class="mdl-step__label">
        <span class="mdl-step__title">
            <span class="mdl-step__title-text">Your Information</span>
            <span class="mdl-step__title-message">Edit this step later</span>
        </span>
            <span class="mdl-step__label-indicator"><span class="mdl-step__label-indicator-content">1</span>
        </span>
        </span>
       /** remove inline css height and overflow it will enable scroll **/
        <div class="mdl-step__content" style="display:inline-block;">

CSS 更改 添加高度属性以定义 mdl-stepper 类的高度

    .mdl-stepper {
  position: relative;
  font-family: "Roboto", sans-serif;
  background-color: white;
  display: block;
  box-shadow: 0px 3px 1px -2px rgba(0, 0, 0, 0.2), 0px 2px 2px 0px rgba(0, 0, 0, 0.14), 0px 1px 5px 0px rgba(0, 0, 0, 0.12);
  padding: 24px 0;
  max-width: 720px;
  width: 100%;
  border-radius: 2px; 
  /**height property based on device screen height you could define it as required **/ 
  height : 80vh;}

试验 mdl-stepper 和 mdl-step 的 css 高度以确定最终元素的外观和感觉。避免使用 !important

的内联样式
