CSS Syntax
Briefly mentioned in the second lecture, the global attributes
id, class, style
are used heavily by
CSS. For more info, check out this
CSS introduction.
CSS Method 1: Internal CSS
Internal styling refers to adding a CSS style
element to the <head> portion of an HTML
document using the <style> element. In an
internal CSS element:
-
#is used to select theidattribute followed by its' value. The value can only be used by a single element. -
.is used to select theclassattribute followed by its' value. The value can be used by multiple elements.
<html>
<!-- Pro Tip: use indentation and line spacing and
breaks to make your code readible -->
<head>
<title>My first HTML document</title>
<style>
/* A CSS comment starts with /* and ends with */
/* In CSS, duplicate declarations are prioritized by the
last read declarations */
p {
color: red;
font-size:
12px; }
#third {
color: purple;
font-weight: bold; }
.green {
color: green; } </style>
</head>
<body>
<!-- Pro Tip: ids should be unique, they also have
priority over classes when both have competing CSS
declarations. -->
<p
id="first">Some text you might write.</p>
<p
id="second"
class="green">Some more text you might write.</p>
<p
id="third"
class="green">Even more text you might write!</p>
</body>
</html>
Results in …
Some text you might write
Some more text you might write.
Even more text you might write!
CSS Method 2: Inline Styling
Inline styling or element styling refers to
applying CSS to the start/opening tag of each
individual HTML element through the use of the
style attribute.
<p
style="color: red; font-size: 12px;">My first CSS</p>
Results in …
My first CSS
Inline styles have the highest priority and will override CSS
declarations found in style elements.
