Fundamental CSS Selectors
In CSS, a selector specifies the HTML elements which will be selected by the rule.
Fundamental selectors include:
HTML element selectors
HTML element selectors select elements based on element type.
An HTML element selector consists of the HTML element itself.
Example, CSS rule to make all paragraphs red:
p { color: red; }
ID selectors
ID selectors select elements based on the ID attribute of a single HTML element.
ID selector rules begin with a pound sign, or hash mark (#).
Example, CSS ID selector rule to set width of HTML element:
#example { width: 1100px; }
#example { color: green; }
The element itself might look like this:
<div id="example"> <!-- more content and HTML elements here --> </div>
Class selectors
Class selectors select elements based on the class attribute of one or more elements.
Class style rules begin with a period (.).
Example, CSS class selector rule to set colors:
.example
{
color: red;
}
.example2
{
background-color: yellow;
}
The HTML elements might look like this:
<p class="example"> This paragraph has red text. </p> <p> This paragraph has default styles. </p> <p class="example class2"> This paragraph has red text and yellow background. </p>
Note how the third paragraph has two class styles: red text, yellow background.
Other CSS selectors
Many other kinds of selectors exist, for a wide range of purposes.
We will discuss some of them in later class sessions.
