Question

大家好我所遇到的问题你可以通过codepen.io看到无论我做什么我都不能让mdl-stepper使其高度与内部的内容相同。

似乎没有真正的getmdl.io。

CSS（我知道这是问题）

并且是的Actuall问题是从那个css文件发生的，你必须复制你Style.css中的所有Css然后更改下面的Css如下（Bcoz它发生步进Mod水平宽度样式）< /强>

更改此

/* STEPPER MOD HORIZONTAL */ @media only screen and (min-width: 841px) { .mdl-stepper--horizontal { -webkit-display: flex; -moz-display: flex; -ms-display: flex; display: flex; flex-direction: row; align-items: baseline; max-width: 840px; padding: 0; min-height: 576px; /* HORIZONTAL STEP */ /* HORIZONTAL STEP LABEL */ /* HORIZONTAL STEP CONTENT */ /* HORIZONTAL STEP ACTIONS */ /* STEPPER MOD HORIZONTAL + MOD LINEAR */ }

至此

/* STEPPER MOD HORIZONTAL */ @media only screen and (min-width: 901px) { .mdl-stepper--horizontal { -webkit-display: flex; -moz-display: flex; -ms-display: flex; display: flex; flex-direction: row; align-items: baseline; max-width: 900px; padding: 0; min-height: 1100px; /* HORIZONTAL STEP */ /* HORIZONTAL STEP LABEL */ /* HORIZONTAL STEP CONTENT */ /* HORIZONTAL STEP ACTIONS */ /* STEPPER MOD HORIZONTAL + MOD LINEAR */ }

注意：此处使用!important规则用于覆盖先前分配的CSS声明

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height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;}

尝试使用mdl-stepper和mdl-step的css高度来计算最终元素的外观。避免使用!important
