1.类似于border、margin、padding的四个方向数值顺序为上右下左。
2.属性z-index参数值越大,则被层叠在最上面。
3.标签<a>和属性display:block和适合在一起。
4.页面加载完才会执行onload,适用于延迟加载。
5.标签<frameset>与标签<body>不能一起使用,因为frameset是一种框架结构,会将整个页面占据掉,所以不要用body进行布局,并确保 doctype 被设置为 "Frameset DTD"。
6.属性display的值的说明:block(块对象的默认值)将对象强制作为块对象呈递,为对象之后添加新行;inline(内联对象的默认值)将对象强制作为内联对象呈递,从对象中删除行;inline-block(将对象呈递为内联对象,但是对象的内容作为块对象呈递)旁边的内联对象会被呈递在同一行内;none(隐藏对象)与 visibility 属性的hidden值不同,其不为被隐藏的对象保留其物理空间。
7.属性required适用于以下 <input> 类型:text、search、url、telephone、email、password、date pickers、number、checkbox、radio和file。
