Question

我正在尝试使用单选按钮制作的标签式导航。我的问题是，当我点击标签时，所选内容的不透明度不会改变，因此内容不会显示。

我的HTML代码：

<div id="container">

<div id="tabs">     
    <input id="tab-1" type="radio" name="tab-group" checked="checked" />
    <label for="tab-1">Tab 1</label>
    <input id="tab-2" type="radio" name="tab-group" />
    <label for="tab-2">Tab 2</label>
    <input id="tab-3" type="radio" name="tab-group" />
    <label for="tab-3">Tab 3</label>
</div>

<div id="content">

    <div id="content-1">
        <form>
            First name:<br>
            <input type="text" name="firstname"><br>
            Last name:<br>
            <input type="text" name="lastname">
        </form> 
    </div>

    <div id="content-2">
        <p class="column-left"><img src="http://ximg.es/200x150" alt="">Lorem ipsum dolor sit amet, consectetur adipisicing elit. </p>
        <p class="column-right"><img src="http://ximg.es/200x150" alt="">Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
    </div>

    <div id="content-3">
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. </p>
        <ul>
            <li>Lorem ipsum dolor sit amet, consectetur adipisicing it.</li>
            <li>Lorem ipsum dolor sit amet, consectetur adipisicing it.</li>
            <li>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</li>
        </ul>
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. </p>
    </div>
</div>

我的CSS代码：

* {
    font-family: Arial, sans;
    margin: 0;
    padding: 0;
    box-sizing: border-box;
    -moz-box-sizing: border-box;
}


#container {
  padding-top: 6em;
  margin: 0 auto;
  width: 50%;
}

#tabs input {
  height: 2.5em;
  visibility: hidden;
}

#tabs label {
  background: #f9f9f9;
  border-radius: .25em .25em 0 0;
  color: red;
  cursor: pointer;
  display: block;
  float: left;
  font-size: 1em;
  height: 2.5em;
  line-height: 2.5em;
  margin-right: .25em;  /*space between tabs*/
  padding: 0 1.5em;
  text-align: center;
}

#tabs input:hover + label {
  background: #ddd;
  color: lawngreen;
}

#tabs input:checked + label {
  background: black;
  color: white;
  position: relative;
  z-index: 6;
}

#content {
  background: red;
  border-radius: 0 .25em .25em .25em;
  min-height: 20em;
  position: relative;
  width: 100%;
  z-index: 5;
}

#content div {
  opacity: 0;
  padding: 1.5em;
  position: absolute;
  z-index: -100;
  transition: all linear 0.1s;
}

#tabs input#tab-1:checked ~ #content #content-1,
#tabs input#tab-2:checked ~ #content #content-2,
#tabs input#tab-3:checked ~ #content #content-3 {
  opacity: 1;    
  z-index: 100;
}


input.visible {
  visibility: visible !important;
}

我认为问题在于3个选择器行“#tabs input＃tab-1：checked~＃content＃content-1”

我试图用不同的语法重写这些行，但没有任何作用。

请帮忙。

Answer 1

匹配#content的div不是任何input的兄弟。这是他们的父母的兄弟姐妹。

我的阿姨不是我的妹妹。

您无法使用CSS选择器从输入到#content-X绘制链接。 There is no parent combinator

您需要使用JavaScript。

<div id="container">

            <li>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</li>
        </ul>
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. </p>
    </div>
</div>

</div>

如果你稍微更改你的HTML，你可以。

基本上，为了#content兄弟姐妹#tabs，我将#tabs关闭div移到了最后。希望这会有所帮助。
