博客介绍了HTML中id选择器的使用，通过id选择器可以为不同HTML元素定义相同样式。文中给出了匹配特定id值的样式规则示例，如匹配id为'green'的元素，以及匹配特定元素（如p元素）且id为特定值的样式规则。
The id Selector
With the id selector you can define the same style for different HTML elements.
The style rule below will match any element that has an id attribute with a value of "green":
#green {color: green} |
The rule above will match both the h1 and the p element:
<h1 id="green">Some text</h1> <p id="green">Some text</p> |
The style rule below will match a p element that has an id with a value of "para1":
p#para1
{
text-align: center;
color: red
} |
The style rule below will match any p element that has an id attribute with a value of "green":
p#green {color: green} |
The rule above will not match an h1 element:
<h1 id="green">Some text</h1> |
