CSS Fonts

The CSS font properties define the font family, boldness, size, and the style of a text.

In this tutorial, you can learn how to decorate fonts using CSS font attributes.

CSS Font Types

There are five font properties are used to design CSS fonts:

  • font-family: The font family of a text is set with the font-family property.
  • font-style: Define the style of the text.
  • font-size: The font-size property sets the size of the text.
  • font-weight: Specifies the weight of a font
  • font-variant: Specifies whether or not a text should be displayed in a small-caps font.

Font Family

The font-family is used to define a family of text like 'Times New Roman', 'Arial', 'Helvetica', 'Times', etc; These are the font-families in CSS.

The CSS font-family can be categorized into two categories:

  • Generic Font Family: A group of font families with a similar look (like "Serif" or "Monospace")
  • Font Family: A specific font family (like "Times New Roman" or "Arial")

What is Serif and Sans-serif fonts?

Serif Fonts

Serif fonts have a small line at the end of the character, which means you can see sharpness at corners of characters.


Sans-Serif Fonts

If you remove the sharpness of Serif Fonts then it will be converted in Sans-Serif fonts.


Example: Font-Family

NOTE: It may possible some browsers not support some font-family. So, you can pass more than one font-family name property value separating them by comma(,).
