带有“下一个”箭头的纯HTML / CSS列表菜单

时间：2015-12-08 11:20:14

标签： html css3 menu tabs

我正在尝试使用指向右侧的箭头生成纯HTML / CSS菜单。只要活动状态是第一个选项卡，一切看起来都很好（http://jsfiddle.net/q03wma6u/）。但是当活动类移动到第二个选项卡时，边框和箭头不会定位到（http://jsfiddle.net/q03wma6u/1/）。

有没有办法只使用HTML / CSS生成这个菜单？

这是怎么回事：

＆＃13;
＆＃13; 
.tabs {
  list-style: none;
  padding: 0;
  margin: 0;
}

.tabs a {
  display: table-cell;
  text-align: center;
  vertical-align: middle;
  color: #4a4a4a;
  text-decoration: none;
  text-transform: uppercase;
}

.tabs > li {
  float: left;
  position: relative;
  border: 1px solid #7B7B7B;
  border-right: none;
  width: 140px;
  height: 50px;
  background: #cccccc;
  cursor: pointer;
  display: table;
}

.tabs > li:before {
  position: absolute;
  top: 50%;
  right: 0;
  margin: -15px -13px;
  border-top: solid 1px #7B7B7B;
  border-right: solid 1px #7B7B7B;
  width: 25px;
  /* .tabs > li height/2 */
  height: 29px;
  /* .tabs > li height/sqrt(3) */
  transform: rotate(30deg) skewY(30deg);
  /* create a rhombus */
  -ms-transform: rotate(30deg) skewY(30deg);
  /* IE 9 */
  -webkit-transform: rotate(30deg) skewY(30deg);
  /* Safari and Chrome */
  background: #cccccc;
  /* 49.1deg = atan(1.15) = atan(height/width) */
  /* percentages are 100 - .tabs > li percentages*/
  content: '';
  z-index: 1;
}

.tabs > li:after {
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  width: 40px;
  background: #cccccc;
  content: '';
  z-index: 2;
}

.tabs > li.active,
.tabs > li.active:before,
.tabs > li.active:after {
  background: #ffffff;
}
＆＃13; 
<ol class="tabs">
  <li class="step1"><a href="#" data-next="step2" class="disabled">Step 1</a></li>
  <li class="step2 active"><a href="#" data-next="step3" class="disabled">Step 2</a></li>
  <li class="step3"><a href="#" data-next="ste4" class="disabled">Step 3</a></li>
  <li class="step4"><a href="#" data-next="step5" class="disabled">Step 4</a></li>
</ol>
＆＃13;
＆＃13;
＆＃13;

结尾li没有边框和方形结束框：

＆＃13;
＆＃13; 
.tabs {
  list-style: none;
  padding: 0;
  margin: 0;
}

.tabs a {
  display: table-cell;
  text-align: center;
  vertical-align: middle;
  color: #4a4a4a;
  text-decoration: none;
  text-transform: uppercase;
}

.tabs > li {
  float: left;
  position: relative;
  border-right: none;
  width: 140px;
  height: 50px;
  background: #cccccc;
  cursor: pointer;
  display: table;
}

.tabs > li:before {
  position: absolute;
  top: 50%;
  right: 0;
  margin: -15px -13px;
  border-top: solid 1px #7B7B7B;
  border-right: solid 1px #7B7B7B;
  width: 25px;
  height: 29px;
  transform: rotate(30deg) skewY(30deg);
  -ms-transform: rotate(30deg) skewY(30deg);
  -webkit-transform: rotate(30deg) skewY(30deg);
  background: #cccccc;
  content: '';
  z-index: 1;
}

.tabs > li:after {
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  width: 40px;
  background: #cccccc;
  content: '';
  z-index: 2;
}

.tabs > li.active,
.tabs > li.active:before,
.tabs > li.active:after {
  background: #ffffff;
}


.tabs > li:last-child:before,
.tabs > li:last-child:after {display:none; content:none;}
＆＃13; 
<ol class="tabs">
  <li class="step1"><a href="#" data-next="step2" class="disabled">Step 1</a></li>
  <li class="step2 active"><a href="#" data-next="step3" class="disabled">Step 2</a></li>
  <li class="step3"><a href="#" data-next="ste4" class="disabled">Step 3</a></li>
  <li class="step4"><a href="#" data-next="step5" class="disabled">Step 4</a></li>
</ol>
