background-repeat属性的定义和用法:
设置或检索对象的背景图像如何铺排填充。
必须先指定background-image属性。
允许提供2个参数，如果提供全部2个参数，第1个用于横向，第二个用于纵向。
如果只提供1个参数，则用于横向和纵向。特殊值repeat-x和repeat-y除外，因为repeat-x相当于repeat no-repeat，repeat-y相当于no-repeat repeat，即其实repeat-x和repeat-y等价于提供了2个参数值。
对应的脚本特性为backgroundRepeat。
语法结构:
background-repeat：repeat-x | repeat-y | [repeat | space | round | no-repeat
取值:
repeat：背景图像在横向和纵向平铺，默认值。
repeat-x：背景图像在横向上平铺。
repeat-y：背景图像在纵向上平铺。
no-repeat：背景图像不平铺。
round：背景图像自动缩放直到适应且填充满整个容器。（CSS3）
space：背景图像以相同的间距平铺且填充满整个容器或某个方向。（CSS3）
浏览器支持:
1.IE8及更早浏览器不支持为background-repeat定义2个参数值；不支持CSS3新增参数值round | space。
2.Firefox4.0-8.0不支持为background-repeat定义2个参数值；不支持CSS3新增参数值round | space。
3.Safari5.1已接受CSS3新增参数值round | space，但还未实现支持。 4.Chrome13.0-16.0已接受CSS3新增参数值round | space，但还未实现支持。
继承性:
无继承性。

What are boolean attributes in HTML? Give some examples.Apr 25, 2025 am 12:01 AMBoolean attributes are special attributes in HTML that are activated without a value. 1. The Boolean attribute controls the behavior of the element by whether it exists or not, such as disabled disable the input box. 2.Their working principle is to change element behavior according to the existence of attributes when the browser parses. 3. The basic usage is to directly add attributes, and the advanced usage can be dynamically controlled through JavaScript. 4. Common mistakes are mistakenly thinking that values need to be set, and the correct writing method should be concise. 5. The best practice is to keep the code concise and use Boolean properties reasonably to optimize web page performance and user experience.
