Introduction to CSS
What is CSS?
Cascading Style Sheets (CSS) describe how the html on a page should appear.
Before CSS developers would apply styles using attributes or special tags on each node of a page. This made markup repetitive and prone to errors.
CSS allows selectors to describe how each piece of matching content should look.
body {
font-size: 15px;
}
a {
color: rebeccapurple;
text-decoration: underline;
}
Using CSS
External style sheets let many pages share the same styles.
<link href="styles.css" rel="stylesheet" type="text/css">
Internal style sheets apply CSS to all matching tags on a page.
<style>
h1 {
font-family: sans-serif;
margin-bottom: 1.5em;
}
</style>
Inline CSS apply styles to a single tag.
<img src="..." style="border: 1px solid red;" />
