    A CSS Selector selects which elements a set of CSS rules applies to. The universal selector (*) applies to EVERYTHING. An element name selector uses the name of the element with NO preceding symbols (for example, h1 would refer to first-level headers).

    For example, say you wanted all first-level headers to be centered. You would have the following:

    Code:
    h1{text-align:center}
    The "h1" in red is your selector.

    Class selectors start with a period ".", and selects elements through the "class" attribute. These refer to groups of elements (grouped by way of having the same class)

    ID selectors start with an octothorpe (also known as a hashtag, "#"), and selects an element through the "id" attribute, the value of which is suppose to be unique within the webpage.

    I wrote an entire chapter on them in my tutorial.

    CSS is used to change HTML elements.

    If you want to style a particular element in the HTML document, you call that HTML element in the CSS and define the style for it.

    For example, you have an h1 tag in the HTML document. If you don't give any style to the h1, its default color is black.

    If you want to give a red color to the h1, you would select the h1 in the CSS and define the font color. Here is an example,

    h1 {color: #ff0000;}

    this is a CSS code and h1 is the selector because it selects all h1s in the HTML. After the selector, we define the style by choosing the appropriate attribute and giving it a value inside the curly braces.

    Hope this answer helps.
