忽略元素盒模型的内边距和边框。 | |
position属性 | |
static —— 默认,表示它不会被特殊定位 | |
relative —— 相对定位,可以修改top\right\bottom\left属性使其偏离正常位置 | |
fixed —— 固定在相对窗口的位置,不会再变动 | |
absolute —— absolute 与 fixed 的表现类似,除了它不是相对于视窗而是相对于最近的“positioned”祖先元素。如果绝对定位(position属性的值为absolute)的元素没有“positioned”祖先元素,那么它是相对于文档的 body 元素,并且它会随着页面滚动而移动。 | |
float —— 实现文字环绕图片 | |
