记录下样式小细节,做回作业~~~
作业内容均是嘎嘎!!!学到啦神马!!!定位!定位!定位!
图像映射既是鼠标放上去给予提示信息 样式完全是用hover属性;效果如图:

1、先看html中,行内元素span居然可以嵌套~~~汗从这才知道,好吧我记下啦!!!
<span class="outer"><span class="inner"><span class="note">GUNDAM-001</span></span></span>
2、关键的样式来哦
绝对定位,绝对的居中:浏览器你变长变短我都居中!!!
650px; height:450px; position:absolute; top:50%; left:50%; margin:-225px 0 0 -325px;
/*这里是注释内容*/ !!!红的背景图可是起了很大作用哦,么有这张图IE是不会有hover时间的,那是因为这是定位的的内容是是空的,只有两个border框,没有图文字也text-indent:-9999px; 甩到一边去啦;
所以这里加个透明的背景图还搞定万恶IE!!!!
.gundam-pic a{ display:block; 200px; height:200px; /*border:1px solid #FF9;*/ position:absolute; text-decoration:none;
color:black;text-indent:-9999px; background: url(images/bg.gif) no-repeat;}
3、小细节
.gundam-pic span { display:block;}
.gundam-pic .outer { /*border:1px solid black;*/}
.gundam-pic .inner { /*border:1px solid white;*/ 196px; height:196px;}
总结同样的样式一起搞,.gundam-pic span { display:block;},之后再补充不同的!!!
<a>标签width/height=200px; 196px; height:196px;
border是会占掉两个像素的,所以内层<span>的要缩小缩小缩小的~~~
4、重头hover
.gundam-pic a:hover {border:2px solid #FF9;}
.gundam-pic a:hover .note{ text-indent:0;background:#FFC url(images/note.gif) repeat-x; padding:5px; text-align:center; border-bottom:1px solid black;border-left:1px solid black; float:right;}
<a>hover,不仅可以hover<a>元素的样式,包含在<a>里的元素也可享受这中特殊待遇哦~~~
这里把被甩出去的文字又给拽回来啦~~~text-indent:0;好厉害哦!!!
绝对定位也很拽的,让你在呆着就给我老实在哪呆着!!!
float:left;position:absolute; left:60px; bottom:-30px;
z-index:100;是防止藏头漏尾~~~
5、就说一点点~~~
.gundam-pic a{ display:block; 200px; height:200px; /*border:1px solid #FF9;*/ position:absolute; text-decoration:none; color:black;text-indent:-9999px; background: url(images/bg.gif) no-repeat;-moz-border-radius-topright:8px;
-moz-border-radius-bottomleft:8px;
/*-webkit-border-radius:8px;*/
-webkit-border-top-right-radius:8px;
-webkit-border-bottom-left-radius:8px;
}
IE不支持的边框圆角化~~~
最后,好脑袋不如赖笔头~~~做笔记做笔记!!!
