Question

我想要一个带有双边框的h2元素。目前我有这个片段，HTML + CSS：

h2.titulo {
  width: 100%;
  margin: 10px 0;
  padding: 10px 0;
  text-transform: uppercase;
  font-weight: 400;
  font-size: 30px;
  display: block;
  color: #8c2638;
  border-bottom: 1px solid #ccc;
  font-size: 25px;
}

h2.titulo span {
  padding: 11px 0;
  font-size: 19px;
  font-size: 25px;
  border-bottom: 1px solid #8c2638;
}

<h2 class="titulo"><span>My title</span></h2>

我希望这个标题具有响应性，当我有一个很长的标题时，我认为最好的方法是文本溢出：省略号，溢出：隐藏。我尝试了这个，但隐藏在h2上的溢出使得红色边框底部消失：

h2.titulo {
  width: 100%;
  margin: 10px 0;
  padding: 10px 0;
  text-transform: uppercase;
  font-weight: 400;
  font-size: 30px;
  display: block;
  color: #8c2638;
  border-bottom: 1px solid #ccc;
  font-size: 25px;
  text-overflow: ellipsis;
  overflow: hidden;
  white-space: nowrap;
}

h2.titulo span {
  padding: 11px 0;
  font-size: 19px;
  font-size: 25px;
  border-bottom: 1px solid #8c2638;
}

<h2 class="titulo"><span>A very very very very very very very very long long title</span></h2>

最接近的方法就是这样，但红色边框并没有与其他边框完全折叠：

h2.titulo {
  border-bottom: 1px solid #ccc;
  font-size: 25px;
  width: 100%;
  margin: 10px 0;
  padding: 0;
  text-transform: uppercase;
  font-weight: 400;
  font-size: 30px;
  display: block;
  color: #8c2638;
  overflow-x: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

h2.titulo span {
  display: inline-block;
  line-height: 100%;
  padding-bottom: 10px;
  border-bottom: 1px solid #8c2638;
}

<h2 class="titulo"><span>Normal title</span></h2>

保证金底部：-1px;由于溢出，在span上没有做到这一点。好吗？

Answer 1

将display: inline-block添加到您的范围内，并从h2删除底部填充。

此外，您的margin-bottom:-1px无效，因为默认情况下span是inline元素，其自身不会发生任何视觉变化，例如padding或margin < / p>

h2.titulo {
  width: 100%;
  margin: 10px 0;
  padding: 10px 0 0;
  text-transform: uppercase;
  font-weight: 400;
  font-size: 30px;
  display: block;
  color: #8c2638;
  border-bottom: 1px solid #ccc;
  font-size: 25px;
  text-overflow: ellipsis;
  overflow: hidden;
  white-space: nowrap;
}

h2.titulo span {
  padding: 11px 0;
  font-size: 19px;
  font-size: 25px;
  border-bottom: 1px solid #8c2638;
  display: inline-block;
}

<h2 class="titulo"><span>A very very very very very very very very long long title</span></h2>

<h2 class="titulo"><span>NORMAL TITLE</span></h2>

已更新：如果您希望折叠边框，请使用box-shadow代替border

将div放在一对div中可以起到作用，因为div是高度自动和全宽度默认值，但你可以设置第二个将它显示为内联块，然后它将正确应用边框。 / p>

＆＃13;

div.titleBox{
 border-bottom: 1px solid #ccc;
}
div.border{
  border-bottom: 1px solid #8c2638;
  display: inline-block;
}
h2.titulo {
    width: 100%;
    margin: 10px 0;
    padding: 10px 0;
    text-transform: uppercase;
    font-weight: 400;
    font-size: 30px;
    display: block;
    color: #8c2638;
    font-size: 25px;
}

h2.titulo span {
    padding: 11px 0;
    font-size: 19px;
    font-size: 25px;
    word-break: break-all;
}

＆＃13;

<div class="titleBox"><div class="border"><h2 class="titulo"><span>This is a short title</span></h2></div></div>


<div class="titleBox"><div class="border"><h2 class="titulo"><span>This is a very very very very very vbery very large one!</span></h2></div></div>

＆＃13;

使用H2（默认情况下为块）可能会让您感到头疼。

＆＃13;

h2.titulo {
    width: 100%;
    margin: 10px 0;
    text-transform: uppercase;
    font-weight: 400;
    font-size: 30px;
    display: block;
    color: #8c2638;
    font-size: 25px;
    border-bottom: 1px solid #ccc;
}

h2.titulo span {
    padding: 11px 0;
    font-size: 19px;
    font-size: 25px;
    word-break: break-all;
    border-bottom: 1px solid #8c2638;
    display: inline-block;
    margin: -1px;
}

＆＃13;

<h2 class="titulo"><span>This is a short title</span></h2>


<h2 class="titulo"><span>This is a very very very very very vbery very large one!</span></h2>

＆＃13;

但你可以解决它删除h2填充并将范围显示为内联块

Answer 3

使用:: after或:: before添加exstra边框怎么样？

我认为这是＆＃34; h2＆＃34;元件
