带边框的 h2 中的文本溢出

Question

我想要一个带有双边框的 h2 元素。目前我有这个sn-p，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，当我的标题很长时，我认为最好的方法是 text-overflow: ellipsis 和 overflow:hidden。我试过这个，但隐藏在 h2 上的溢出使红色边框底部消失：

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>

最接近的方法是这样，但红色边框与另一个边框不完全折叠：

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>

和margin-bottom:-1px;由于溢出，在跨度上不起作用。请问有什么办法吗？

Answer 1

将display: inline-block 添加到您的跨度并从h2 中删除底部填充。

您的margin-bottom:-1px 也不起作用，因为span 默认是inline 元素，它本身不会像padding 或margin 那样提供视觉变化

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>

更新：如果您想折叠边框，请使用box-shadow 而不是border

  display: block;
  color: #8c2638;
  box-shadow: 0px -1px 0px 0px #ccc inset;
  font-size: 25px;
  text-overflow: ellipsis;
  overflow: hidden;
  white-space: nowrap;
}

h2.titulo span {
  padding: 11px 0;
  font-size: 19px;
  font-size: 25px;
  box-shadow: 0px -1px 0px 0px #8c2638 inset;
  display: inline-block;
  position: relative;
}

<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>

将 div 放在一对 div 中可以解决问题，因为 div 默认为自动高度和全宽，但您可以将第二个设置为将其显示为内联块，然后它将正确应用边框。

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;
}

<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>

使用默认为块的 H2 执行此操作可能会让您头疼。

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;
}

<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>

但你可以解决它删除 h2 填充并将跨度显示为内联块

使用 ::after 或 ::before 添加额外边框怎么样？

我想这是“h2”元素的额外边框
