HTML设置水平分割线_html/css_WEB-ITnose
在Web中使用水平分割线可以分割不同的文字段落或者其它网页组件,轻松地修饰了段落排版,使之更美观。当然,水平分割线还可以更加明显地突出某一段重要的文字,使之更加醒目。
使用
标签可以轻松地设置一条水平线。方法如下:
HTML设置水平分割线
1. HTML设置一条水平分割线
<hr />
这是水平分割线的最基本应用。它是居中对齐的。
2. HTML设置水平分割线的宽度
<hr width="200" />
水平分割线的宽度为像素(px)或者相对于屏幕宽度的百分比(%)。比如:
<hr width="200px" /> <!--单位为像素。默认值是将px去掉,成为上面的格式--><hr width="20%" /> <!--单位是相对于屏幕宽度的百分比-->
3. HTML设置水平分割线的粗细
<hr size="30" />
水平分割线的粗细单位仍然是像素(px)。
4. HTML去掉水平分割线的阴影
<hr noshade="noshade" />
一般情况下,水平分割线是带有阴影的,具体显示为一条突出的或者凹下去的线条。使用此属性,可以去掉分割线的阴影,使之成为一条无阴影效果的实心线。
5. HTML设置水平分割线的对齐方式
<hr width="30%" align="left" />
水平分割线的对齐方式默认为居中对齐。使用align属性可以改变它的对齐方式。并且只有当它的宽度设置小于屏幕的宽度时,才会显示出对齐方式的设置效果。
6. HTML设置水平分割线的颜色
<hr color="#FF0000" />
可以给水平分割线设置不同的颜色。
7. HTML设置水平分割线的title属性
<hr size="30" title="设置水平分割线的title属性" />
当浏览者将鼠标悬停在分割线上时会出现属性值设置的提示内容。
8. HTML水平分割线的综合应用
<hr width="300" size="20" noshade="noshade" align="right" color="#0000FF" />
可以分别设置
的属性:size、width、align、color和noshade等。属性不用全部设置,而是根据需要选择某些属性进行设置,未设置的属性浏览器会以默认的方式显示。
默认方式:浏览器在遇到属性不全的标签时,对于未设置的属性将根据浏览器内部定义好的样式进行显示。
