ID selector

We can also use the id selector. It creates the id attribute of a HTML tag and selects a specific element on the page. An element of a page must have a unique id. It can use only once in a page. To declare a id selector we use # (hash) character before the name of id. Write in Style.css

#redleft{
	Color:red;
	text-align:left;
}
#blueright
{
	Color:blue;
	text-align:right;
}

The class selector

We can also use the class selector. It creates the class attribute of a HTML tag. It is used to create a group of elements on the page with the same class. The looks of the elements within a class are same. To declare a class selector we use (.) DOT character before the name of the class.
