我正在尝试创建一个在主div后面有一条线的横幅/ tittle。我希望tittle的线和文本位于中间(垂直),如图所示:
问题是,如果我更改浏览器的大小,hr
和文本不会对齐(垂直)。以下是第一个版本:
.section {
clear: both;
padding: 0px;
margin: 0px;
}
.col {
text-align:center;
display: block;
float:left;
margin: 1% 0 1% 0%;
}
.col:first-child { margin-left: 0; }
.group:before,
.group:after { content:""; display:table; }
.group:after { clear:both;}
.group { zoom:1; /* For IE 6/7 */ }
.span_3_of_3 { width: 100%; }
.span_2_of_3 { width: 66.66%; }
.span_1_of_3 { width: 33.33%; }
@media only screen and (max-width: 480px) {
.col { margin: 1% 0 1% 0%; }
.span_3_of_3, .span_2_of_3, .span_1_of_3 { width: 100%; }
}
#middle
{
background:#CCC;
color:#FC3699;
height:100px;
margin-top:0;
line-height:100px;
}
hr {
margin-top:40px;
border:2px solid #FC3699;
}
<div class="section group">
<div class="col span_1_of_3">
<div class="topsection">
<div class="header"><hr /></div>
</div>
</div>
<div id="middle" class="col span_1_of_3">
aaaaaaa
</div>
<div class="col span_1_of_3">
<div class="topsection">
<div class="header"><hr /></div>
</div>
</div>
</div>
这是第二个版本。而不是有3列我可以使用下面的代码片段。问题出在这一行:
高度:100像素; line-height:100px;
我希望高度为100%。但行高不能:
.main {
height:100%;
min-height:100px;
display: block;
text-align: center;
overflow: hidden;
white-space: nowrap;
}
.main > span {
width:200px;
height:100px;
line-height: 100px;
background:#F1F1F1;
position: relative;
display: inline-block;
}
.main > span:before,
.main > span:after {
content: "";
position: absolute;
top: 50%;
width: 9999px;
height: 3px;
background: #FC3699;
}
.main > span:before {
right: 100%;
margin-right: 15px;
}
.main > span:after {
left: 100%;
margin-left: 15px;
}
<div class="main">
<span style="vertical-align: middle;">Text</span>
</div>
这是第三个也是最好的版本,我只需要text-aling:center;
文本。但即使我在CSS中添加它,它也不起作用:
.main {
height:100%;
min-height:100px;
display: block;
text-align: center;
overflow: hidden;
white-space: nowrap;
}
.main > span {
width:200px;
height:100px;
line-height: 100px;
background:#F1F1F1;
position: relative;
display: inline-block;
}
.main > span:before,
.main > span:after {
content: "";
position: absolute;
top: 50%;
width: 9999px;
height: 3px;
background: #FC3699;
}
.main > span:before {
right: 100%;
}
.main > span:after {
left: 100%;
}
#child {
display: table-cell;
vertical-align: middle;
}
<div class="main">
<span><div id="child">Text</div></span>
</div>

如果flexbox
是一个选项,这很容易 - 您只需要提供
display: flex;
justify-content:center;
align-items:center;
您可以取消所有定位和宽度计算 - 请参阅下面的演示:
.main {
height: 100%;
min-height: 100px;
display: flex;
justify-content:center;
align-items:center;
width: 100%;
text-align: center;
white-space: nowrap;
}
.main > span {
width: 200px;
height: 100px;
background: #F1F1F1;
display: inline-flex;
justify-content:center;
align-items:center;
}
.main:before,
.main:after {
content: "";
height: 3px;
background: #FC3699;
flex:1;
}
<div class="main">
<span>Text</span>
</div>

问题是1%
的{{1}}保证金和.col
的固定排名。
我建议使用hr
作为包装器并将其垂直放置在包装器中。这样即使更改了包装器高度,行也将相对于包装器位于相同的位置( jQuery仅用于演示):
:before
$(document).ready(function() {
setInterval(function() {
$('.col3').animate(
{height: 300},
2000,
function() {
$('.col3').animate({height: 120}, 2000);
});
}, 5000);
})
* {
box-sizing: border-box;
}
.col3 {
width: 33.33333%;
height: 120px;
display: inline-block;
background-color: grey;
color: #fc3699;
z-index: 10;
position: relative;
margin: 1% 0;
}
.col3:before {
content: '';
height: 100%;
vertical-align: middle;
display: inline-block;
}
.wrapper {
position: relative;
text-align: center;
}
.wrapper:before {
content: '';
display: block;
width: 100%;
height: 4px;
background-color: #fc3699;
position: absolute;
left: 0;
top: 50%;
margin-top: -2px;
}

我就是这样做的,带有一个图标:
gulp.task('watch', function() {
gulp.watch('dev/templates/**/*.jade').on('change', function(changedFile) {
return compileJade(isPartial(changedFile) ? findAffectedFiles(changedFile) : changedFile);
});
});
CSS:
<div class="propos_underline marginbottom">
<div class="icon icon-cubes"></div>
<div class="clear"></div>
</div>
结果:
jade-inheritance
