For example, the following attribute selector matches all H1 elements that specify the "title" attribute, whatever its value.
例如，如下的属性选择符匹配那些指定了“title ”属性的H1元素，而不论其值为什么？
A simple selector is either a type selector or universal selector followed immediately by zero or more attribute selectors, ID selectors, or pseudo-classes, in any order.
一个简单选择符或者是一个类型选择符，或者是一个全局选择符，紧跟在后的是零个或多个属性选择符，ID选择符或伪类，次序任意。
So the return value (sort of a misnomer, but still a useful way to think about things) for an attribute selector is a value; for an element, it's a node set (containing a single node).
因此对于属性选择器，返回值（虽然不确切但是很有用）是一个值，对于一个元素则是一个节点集（包含一个节点）。
The selector in the following rule, which combines descendant and attribute selectors, matches any element that (1) has the "href" attribute set and (2) is inside a P that is itself inside a DIV
下面规则中的选择符结合了派生选择符和属性选择符，它匹配任何元素，如果(1)该元素设置了"href"属性；且(2)包含在一个P元素内，而P元素又包含在一个DIV元素内
Like the class, an ID selector is based on the value of an attribute, but in this case, it's the ID attribute.
与类选择符相似，ID选择符也基于一个属性的值，但这个属性是ID属性。
In the following example, the selector matches all SPAN elements whose "class" attribute has exactly the value "example".
下面这个例子，选择符匹配所有指定“class ”属性为“example ”的SPAN元素。
A class selector selects all elements that have a class attribute with a particular value.
类选择符选择class属性为特定值的所有元素。
Here, the selector matches all SPAN elements whose "hello" attribute has exactly the value "Cleveland" and whose "goodbye" attribute has exactly the value "Columbus".
这里，选择符匹配那些SPAN元素，其“hello ”属性设置为“Cleveland ”而“goodbye ”属性设置为“ Columbus ”。
We recommend picking a selector name with a prefix to ensure that it cannot conflict with any standard HTML attribute, now or in the future.
我们建议在给选择器起名时加个前缀，以确保它不会和任何标准的HTML属性冲突，无论是现在还是未来。
Do spell non-element selectors in lower camel case unless the selector is meant to match a native HTML attribute.
坚持用小驼峰形式拼写非元素选择器，除非该选择器用于匹配原生HTML 属性。
Is there an existing or upcoming CSS3 selector for matching substrings of attribute names?
有一个现有的或即将到来的CSS3选择器的属性的名称匹配的子串？
