Tab頁面切換的功能我們已經和大家分享過很多,本文我們主要和大家紹CSS實現Tab頁切換實例代碼,需要的朋友可以參考下,希望能幫助到大家。
1.hover
移入其父元素.navI時,觸發滑鼠的hover態,為父元素新增樣式為position:relative ;z-index:1;。從而提升了層級z-index。在其子元素導航內容的層級比拼中,“子憑父貴”,父元素層級高的,其導航內容在重疊狀態中顯示在最上面
<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> <p 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> </p>
2.錨點
點擊導航標題時,觸發target偽類,改變對應的導航內容的層級z-index,從而使當前導航內容在三個導航內容中勝出,在最上層顯示;同時,改變目前導航標題的樣式
<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> <p 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> </p>
3.radio
點擊導航標題時,觸發checked偽類,改變對應的導航內容的層級z-index,從而使當前導航內容在三個導航內容中勝出,在最上層顯示;與此同時,改變目前導覽標題的樣式
<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> <p 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> </p>
