Question

我尝试将箭头形状添加到div中。我设法将它添加到div的末尾，但我正在努力弄清楚如何在不使用新类的情况下将其添加到前面。是否有可能只用一个类来实现它？

编辑：我用不同的形状方法回答问题，我认为它们都非常有用：

＆＃13;

public interface IPersonViewModel
{
    [Required]
    string MobileNumber { get; set; }
}

public class PersonViewModel : IPersonViewModel
{
    // this will NOT get the [Required] attribute from the interface
    public string MobileNumber { get; set; }
}

＆＃13;

.arrow {
  margin-left: 100px;
  position: relative;
  background: pink;
  width: 400px;
  height: 100px;
  text-align:center;
  line-height:100px;
  margin-bottom:10px;
}

.arrow:after {
  border: solid transparent;
  content: " ";
  position: absolute;
  border-bottom-color: white;
  border-width: 50px;
  left: 0;
  top: 0;
  transform: rotate(90deg);
}

.arrow:before {
  border: solid transparent;
  content: " ";
  position: absolute;
  border-bottom-color: pink;
  border-width: 50px;
  left: 400px;
  top: 0;
  transform: rotate(90deg);
}

Answer 1

你需要一个内在元素。这个元素是什么，纯粹取决于你。在这里，我使用了<span>来显示左箭头。

.arrow {
  float: left;
  width: 128px;
  height: 50px;
  background-color: white;
  border: 1px solid green;
  position: relative;
  margin-right: 40px;
  text-align: center;
  border-left: none;
}

.arrow:after,.arrow span:after  {
  content: '';
  position: absolute;
  top: 0px;
  left: 128px;
  width: 0;
  height: 0;
  border: 25px solid transparent;
  border-left: 12px solid white;
  z-index: 2;
}

.arrow:before,.arrow span:before {
  content: '';
  position: absolute;
  top: 0px;
  left: 129px;
  width: 0;
  height: 0;
  border: 25px solid transparent;
  border-left: 12px solid green;
  z-index: 1;
}
.arrow span:after {
  left: 0;
}

.arrow span:before {
  left: 1px;
}

<div class="arrow"><span></span>1</div>
<div class="arrow"><span></span>2</div>
<div class="arrow"><span></span>3</div>
<div class="arrow"><span></span>4</div>
<div class="arrow"><span></span>5</div>

Answer 2

我修改过V形状，在这个页面上：https://css-tricks.com/examples/ShapesOfCSS/（借用了想法，归功于Anthony Ticknor先生：））

.chevron {
  position: relative;
  text-align: center;
  height: 60px;
  width: 260px;
  line-height:60px;
 
 margin-bottom:10px;

}

.chevron:before {
   content: ''; 
   position: absolute; 
   top: 0; 
   left: 3%; 
   height: 50%; 
   width: 100%;
  
    transform: skew(25deg, 0deg);
    border:1px solid red;
    border-bottom:none;
}

.chevron:after {
   content: ''; 
   position: absolute; 
   top: 50%; 
   left: 3%; 
   height: 50%; 
   width: 100%;
   
    transform: skew(-25deg, 0deg);
       border:1px solid red;
    border-top:none;
}

<div class="chevron">1</div>
<div class="chevron">2</div>

所以，一个div和两个伪元素，在需要的地方隐藏了边框。

在div前面添加一个箭头
