我被要求创建这个标题,纯粹用css,它甚至可能吗?
文本的背景需要保持透明,h2需要跨越任何容器的宽度,并且左右边框自动填充剩余空间。
h2 {
font-size:42px;
line-height:48px;
width:100%;
overflow: hidden;
&:before {
content:'';
position:relative;
padding-left:50px;
padding-right:10px;
margin-right:10px;
margin-bottom:10px;
background:red;
height:3px;
display:inline-block;
}
&:after {
content:'';
margin-left:10px;
width:100%;
background:red;
height:3px;
display:inline-block;
}
}
左侧很容易,但是我被困在右侧。

我似乎无法弄清楚如何只让正确的线条填充容器右侧的剩余空间。

您可以在"urn:x-local:objective_1"
伪元素上使用margin-right:-100%;
和vertical-align:middle;
。 (根据这个答案:Line separator under text and transparent background):
:after
h2 {
font-size: 42px;
line-height: 48px;
width: 100%;
overflow: hidden;
}
h2:before, h2:after {
content: '';
display: inline-block;
vertical-align:middle;
width:50px;
height:3px;
border-top:1px solid #fff;
border-bottom:1px solid #fff;
}
h2:after {
width:100%;
margin-right: -100%;
}
/**** FOR THE DEMO ***/
body{background-image: url('https://farm9.staticflickr.com/8760/17195790401_ceeeafcddb_o.jpg');background-repeat:no-repeat;background-size:cover;color:#fff;}
请注意,我还简化了您的CSS。

如果您对绝对定位不太满意,可以
h2 {
font-size:42px;
line-height:48px;
width:100%;
overflow: hidden;
&:before {
content:'';
position:relative;
padding-left:50px;
padding-right:10px;
margin-right:10px;
margin-bottom:10px;
border-top:1px solid #000;
border-bottom:1px solid #000;
height:3px;
display:inline-block;
}
&:after {
content:'';
margin-left:10px;
width:50%;
height:3px;
position:absolute;
border-top:1px solid #000;
border-bottom:1px solid #000;
top:60px;
}
}
需要调整,但在jsfiddle中,这可以获得你需要的东西

以下是使用display: table;
的解决方案
和display: table-cell;
标题内容后侧面的线条会增长和缩小。
.headline {
display: table;
line-height: 3px;
white-space: nowrap;
}
.headline:before {
width: 20%;
height: 2px;
margin-top: 20px;
border-right: 10px solid transparent;
}
.headline:after {
width: 80%;
border-left: 10px solid transparent;
}
.headline:before,
.headline:after {
content: '';
display: table-cell;
border-top: 1px solid black;
border-bottom: 1px solid black;
}
<h2 class="headline">
Headline
