CSS, short for Cascading Style Sheets, is a language used to control the presentation of HTML and XHTML documents.
CSS, short for Cascading Style Sheets, is a language used to control the presentation of HTML and XHTML documents. Each CSS document is made out of rulesets preceded by a selector - a set of rules for matching HTML and XHTML elements, containing property-value pairs that defines the presentation of the elements matching the selector. CSS is presented as a collection of features (CSS1, CSS2, CSS3).
Sample CSS File
a { /* This removes the underline from all anchors and change their colors to orange */
text-decoration: none;
color: orange;
}
#article a.tag { /* Selectors with greater Specificity override less specific ones */
color: #4A6B82;
}
#article #sidebar > h3 + p:first-child a {
/* Complex selectors can be created from joining multiple simple ones together */
border-bottom: 1px solid #333;
font-style: italics;
}
