javascript - 使选项卡正确对齐

Question

我正在尝试向面板添加选项卡，但选项卡未与从中生成的框对齐(对齐)。我应该怎么做才能纠正这个问题？这是实际代码:JSFiddle .我正在尝试制作如下屏幕截图所示的 View :

<main>
  <input id="tab1" type="radio" name="tabs" checked>
  <label for="tab1">Tab1</label>
  <input id="tab2" type="radio" name="tabs">
  <label for="tab2">Tab2</label>  
  <section id="content1"> 
    <form id="msform">
    <fieldset id="firstField">
        <h2 class="fs-title">Do yo have a fever?</h2>
        <input type="button" name="feveryes" class="next action-button" value="Yes" />
        <input type="button" name="feverno" class="next action-button" value="No" />
        <br><input type="button" name="previous" class="previous action-button" value="Reset" />
    </fieldset>
    <fieldset id="feveryes">
        <h2 class="fs-title">Do you have a cough?</h2>
        <input type="button" name="coughyes" class="next action-button" value="Yes" />

        <br><input type="button" name="previous" class="previous action-button" value="Reset" />
    </fieldset>
    <fieldset id="coughno">
        <h2 class="fs-title">Be careful!</h2>

    </fieldset>  
</form>

<section id="content2">TEST TEST TEST
  </section>
</main>

Answer 1

只需删除部分的填充和表单的边距:

section {
  display: none;
  padding: 20px 0 0;
  border-top: 1px solid #ddd;
  padding: 0;
}


#msform fieldset {
    background: white;
    border: 0 none;
    border-radius: 3px;
    box-shadow: 0 0 15px 1px rgba(0, 0, 0, 0.4);
    padding: 20px 30px;

    box-sizing: border-box;
    width: 80%;
    //margin: 0 10%;  // no margin

    /*stacking fieldsets above each other*/
    position: absolute;
}
