CSS实现Tab页切换实例代码,csstab切换实例


1.hover

移入其父元素.navI时,触发鼠标的hover态,给父元素添加样式为position:relative;z-index:1;。从而提升了层级z-index。在其子元素导航内容的层级比拼中,“子凭父贵”,父元素层级高的,其导航内容在重叠状态中显示在最上面

<style>
body,p{margin: 0;}
h2{margin: 0;font-size:100%;}
ul{margin: 0;padding: 0;list-style: none;}   
a{text-decoration: none;color:inherit;}
.box{width: 572px;border: 1px solid #999;overflow: hidden;}
.nav{margin-left: -1px;font: 14px "微软雅黑";overflow: hidden;background-color: #f1f1f1;}
.navI{float: left;width: 33.333%;box-sizing: border-box;}
.navI-tit{line-height: 40px;text-align: center;cursor: pointer;border-left: 1px solid #cecece;border-bottom: 1px solid #cecece;}
.navI-txt{width: 572px;height:200px;text-indent:2em;line-height: 2;background:#fff;}
.ml1{margin-left: -100%;}
.ml2{margin-left: -200%;}
.navI_active{position:relative;z-index:1;}
/*重点代码*/
.navI:hover{position:relative;z-index:1;}
.navI:hover .navI-tit{background:#fff;border-bottom:none;}
</style>

<div class="box">
    <ul class="nav">
        <li class="navI navI_active">
            <h2 class="navI-tit">课程</h2>
            <p class="navI-txt">课程内容</p>
        </li>
        <li class="navI">
            <h2 class="navI-tit">学习计划</h2>
            <p class="navI-txt ml1">学习计划内容</p>
        </li>
        <li class="navI">
            <h2 class="navI-tit">技能图谱</h2>
            <p class="navI-txt ml2">技能图谱内容</p>
        </li>
    </ul>   
</div>

2.锚点

点击导航标题时,触发target伪类,改变对应的导航内容的层级z-index,从而使当前导航内容在三个导航内容中胜出,在最上层显示;与此同时,改变当前导航标题的样式

<style>
body,p{margin: 0;}
h2{margin: 0;font-size:100%;}
ul{margin: 0;padding: 0;list-style: none;}   
a{text-decoration: none;color:inherit;}
.box{width: 572px;border: 1px solid #999;overflow: hidden;}
.nav{margin-left: -1px;font: 14px "微软雅黑";overflow: hidden;background-color: #f1f1f1;}
.navI{float: left;width: 33.333%;box-sizing: border-box;position:relative;}
.navI-tit{position:absolute;top:0;left:0;right:0;box-sizing: border-box;line-height: 40px;height: 40px;text-align: center;cursor: pointer;border-left: 1px solid #cecece;border-bottom: 1px solid #cecece;}
.navI-txt{width: 572px;height:200px;margin-top: 40px;text-indent:2em;line-height: 2;background:#fff;}
.ml1{margin-left: -100%;}
.ml2{margin-left: -200%;}
.navI_active{z-index:1;}
/*重点代码*/
.navI-txt:target{position:relative;z-index:1;}
.navI-txt:target ~ .navI-tit{background:#fff;border-bottom:none;}
</style>
<div class="box">
    <ul class="nav">
        <li class="navI navI_active">
            <p class="navI-txt" id="kc">课程内容</p>
            <a class="navI-tit" href="#kc">课程</a>
        </li>
        <li class="navI">
            <p class="navI-txt ml1" id="xx">学习计划内容</p>
            <a class="navI-tit" href="#xx">学习计划</a>
        </li>
        <li class="navI">
            <p class="navI-txt ml2" id="jn">技能图谱内容</p>
            <a class="navI-tit" href="#jn">技能图谱</a>
        </li>
    </ul>   
</div>

3.radio

点击导航标题时,触发checked伪类,改变对应的导航内容的层级z-index,从而使当前导航内容在三个导航内容中胜出,在最上层显示;与此同时,改变当前导航标题的样式

<style>
body,p{margin: 0;}
ul{margin: 0;padding: 0;list-style: none;}
a{text-decoration: none;color: inherit;}
input{margin: 0;padding: 0;border:none;}
.box{width:572px;border:1px solid #999;font:14px "微软雅黑";overflow:hidden;}
.nav-tit{margin-left: -1px;height: 40px;line-height: 40px;text-align: center;background-color: #f1f1f1;overflow: hidden;}
.nav-titI{box-sizing: border-box;float: left;width: 33.333%;border-left: 1px solid #cecece;border-bottom: 1px solid #cecece;cursor: pointer;}
.nav-txt{height: 200px;}
.nav-txtI{height: 200px;display:block;width: 100%;text-indent: 2em; line-height: 2;}
/*重点内容*/
.nav-txt{overflow: hidden;}
.nav-titI:hover{background-color: #fff;border-bottom:none;}
</style>
<div class="box">
    <nav class="nav-tit">
        <label class="nav-titI" for="kc">课程</label>
        <label class="nav-titI" for="xx">学习计划</label>
        <label class="nav-titI" for="jn">技能图谱</label>
    </nav>
    <nav class="nav-txt">
        <input class="nav-txtI nav-txtI_active" id="kc" value="课程内容" readonly>
        <input class="nav-txtI" id="xx" value="学习计划内容" readonly>
        <input class="nav-txtI" id="jn" value="技能图谱内容" readonly>
    </nav>
</div>
