You can also try using Pseudoclass :after.. I have used this kind of styling in one of my applications.
您也可以尝试使用 Pseudoclass :after。. 我在我的一个应用程序中使用了这种样式。
h1:after
{
content:' ';
display:block;
border:2px solid black;
}
You can tidy up little more to style something like this:- http://jsfiddle.net/5HQ7p/
你可以稍微整理一下来设计这样的东西:- http://jsfiddle.net/5HQ7p/
h1:after {
content:' ';
display:block;
border:2px solid #d0d0d0;
border-radius:4px;
-webkit-border-radius:4px;
-moz-border-radius:4px;
box-shadow:inset 0 1px 1px rgba(0, 0, 0, .05);
-webkit-box-shadow:inset 0 1px 1px rgba(0, 0, 0, .05);
-moz-box-shadow:inset 0 1px 1px rgba(0, 0, 0, .05);

You should use the border-bottom
CSS property.
您应该使用border-bottom
CSS 属性。
For HTML, use the below code:
对于 HTML,请使用以下代码:
<h1>Introduction</h1>
For CSS, use the below code:
对于 CSS,请使用以下代码:
h1
{
border-bottom:1px solid #CCC;
padding-bottom:3px;
}
In case, you want to use the float:left, float:right
properties, then you have to use width:100%
property also. padding-bottom
is to optionally give some space between the text and horizontal line.
如果您想使用float:left, float:right
属性,那么您也必须使用width:100%
属性。padding-bottom
是可选地在文本和水平线之间留出一些空间。
h1
{
border-bottom:1px solid #CCC;
float:left;
width:100%;
padding-bottom:3px;
}
