font-size property?
- The font-size property sets the size of a font.
This will be our boilerplate:
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title> Font Sizes in CSS </title>
<style>
</style>
</head>
<body>
</body>
</html>
Font Size Property values
i) px: The px value is normatively defined as being exactly 1/96th of an inch.
.p {
font-size: 20px;
}
ii) em: Relative to the font size of the element (2em means 2 times the size of the current font).
.p {
font-size: 2em;
}
iii) rem: This property value is relative to the font size of the root element.
.p {
font-size: 4rem;
}
