font-family Back to top

The font-family property allows you to choose a primary font and fallback fonts for an HTML element.

In this example:

the primary font is Tahoma
if Tahoma isn't on the person's computer, it will try the first fallback font, Arial
if Arial isn't on the person's computer, it will try Verdana
if none of these fonts are on the person's computer, it will try the basic font type sans-serif

body {
  font-family: Tahoma, Arial, Verdana, sans-serif;
}

font-size Back to top

The font-size property sets size of the text.

Default Font Size

The default font-size for the <body> is 16px.

So if you don't set the font-size, it will automatically be 16px.

PX Values

If you want an exact size, you can use a px value.

In this example, the base font-size for the webpage is 10px.

So, paragraphs are 10px. And since the <h1> is double the base font size, so it is 20px.

body {
  font-family: Tahoma, Arial, Verdana, sans-serif;
  font-size: 10px;
}

Here is the same webpage with a 20px base font-size.

Paragraphs are 20px and the <h1> is 40px.

body {
  font-family: Tahoma, Arial, Verdana, sans-serif;
  font-size: 20px;
}

You can set the font-size for individual elements, not just the <body>.

Here the <h1> is 60px.

body {
  font-family: Tahoma, Arial, Verdana, sans-serif;
  font-size: 20px;
}
h1 {
  font-size: 60px;
}

EM, % and VW Font Sizes

Possible Values	Description	Example
px value	like 36px	This text is 36px. It is an exact size.
em value	like 3em	This text is 3em. 1em is equal to the current font size. 1em = 16px. 3em = 16x3 = 48px.
percent value	like 200%	This text is 200%. 100% is equal to the current font size. 100% = 16px. 200% = 16x2 = 32px.
vw value	like 3vw	This text is 3vw. It resizes depending on the width of the browser. (try resizing your browser)

Five Font Types Back to top

All fonts are one of these types:

serif - the characters have extra decorations called serifs. They are used frequently in books, magazines and newspapers
sans-serif - the characters do not have serifs (sans means "without")
cursive - appear as if they are handwritten
fantasy - decorative/playful fonts that are used for headers only
monospace - every character has the same width so they always line up

Serif Fonts

have extra decorations on the edges of the letters
these decorations are called serifs
these fonts are formal and elegant

Sans-Serif Fonts

do not have extra decorations
sans means without
these fonts are more modern looking

Serif vs. Sans-Serif

Cursive Fonts

not always cursive
but look handwritten

Fantasy Fonts

are playful and decorative
should be used for headers only
do not work well as the main font for paragraphs

Monospace Fonts

every character has the same width
all the letters line up
used in code editors like Dreamweaver
