1.首先导入reset.css文件夹来去除基本的样式,性能比*{padding:opx;margin:0px;
}好。
2.处理IE6图片透明问题在body中
清除div img a h1的透明问题;
3. 关于左边设置外边距还是内边距问题,首先width=940px,若设置padding则撑开原先的定义好的宽度,到时候需要重新定义宽度,所有用margin。
4. title作用:鼠标移入到图片就会有提示文字。 alt:描述这张图片
5. 导航条
1、 截一个像素的图作为背景图,样式→固定大小→图像 →裁剪→文件→存储为web所用格式→存储到img下。
2、 来晒选图层。
3、 查看字体
查看字体颜色
4、 选中图层,Alt+图标位置,留下你要选的图层,过滤掉不要的图层
