HTML框架标签 - zhongJaywang
与HTML框架有关的标签主要有三种:
-
<frameset></frameset>
框架结构标签 -
<frame>
框架标签 -
<iframe></iframe>
内联框架标签
一、 先来说第一种框架结构标签 <frameset></frameset>
,其主要属性是rows和cols,使用如下:
<span style="color: #0000ff;"><span style="color: #800000;">html</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">frameset </span><span style="color: #ff0000;">cols</span><span style="color: #0000ff;">="25%,50%,25%"</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><span style="color: #800000;">frame </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="frame_a.htm"</span> <span style="color: #0000ff;">/></span> <span style="color: #0000ff;"><span style="color: #800000;">frame </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="frame_b.htm"</span> <span style="color: #0000ff;">/></span> <span style="color: #0000ff;"><span style="color: #800000;">frame </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="frame_c.htm"</span> <span style="color: #0000ff;">/></span> <span style="color: #0000ff;"></span><span style="color: #800000;">frameset</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"></span><span style="color: #800000;">html</span><span style="color: #0000ff;">></span></span></span></span></span></span>
重要的提示:
不能将 标签与
<frameset></frameset>
标签同时使用!不过,假如你添加包含一段文本的<noframes></noframes>
标签,就必须将这段文字嵌套于标签内。
二、<frame>
标签定义 frameset 中的一个特定的窗口(框架)。其常用的属性如下:
- frameborder,规定是否显示框架周围的边框。值:0/1;
- name,规定框架的名称。值:name;
- noresize,规定无法调整框架的大小。值:noresize;
- scrolling,规定是否在框架中显示滚动条。值:yes/no/auto;
- src,规定在框架中显示的文档的 URL。值:URL;
- marginheight,定义框架的上方和下方的边距。
- marginwidth,定义框架的左侧和右侧的边距。
- longdesc,规定一个包含有关框架内容的长描述的页面。(由于浏览器对 longdesc 属性的支持性非常差,没有必要使用该属性。)
三、内联框架<iframe></iframe>
用于在网页内显示网页
<span style="color: #0000ff;"><span style="color: #800000;">iframe </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="URL"</span><span style="color: #0000ff;">></span><span style="color: #800000;">iframe</span><span style="color: #0000ff;">></span></span>
