Key Font Properties in Css

 The following properties are often used for tighter control. Most are self-explanatory, so let’s
breeze through them; we’ll combine them all in a sample template at the end of the chapter.

font-weight
The font-weight property sets how thick or thin characters in text should be displayed. Typically,
the declaration will either be normal or bold, although some browsers support numeric values
in increments of 100. These are 100 (lightest), 200, 300, 400 (same as normal), 700 (same as bold),
800, and 900 (even bolder!).

font-style
Again, this property is pretty obvious. The default is normal, but typically you would use this
property to declare any text that needs to be rendered in italics. Values are normal, italic, and
oblique. When you specify an oblique font style, the browser looks for any available font with
“oblique” in its name or, failing that, one with “italic” in its name.

font-variant
The font-variant property is used to display text in a small-caps font, which means that all the
lowercase letters are converted to uppercase letters, but all the letters in the small-caps font
have a smaller font size compared to the rest of the text. This is useful for secondary, lessimportant
info such as stats, figures, or footer information. Possible values are simply normal or
small-caps.
Note that the browser will use a proper small-caps font if one is available; otherwise the
effect is done computationally. You can see an example of small caps a little later in Figure 4-9.

text-transform
Not strictly a font property, but it controls the font, so it is included here. This property is a
natural antidote to font-variant, where all characters can be rendered uppercase without
reducing font size. The text-transform:uppercase declaration is especially useful for headings,
where it is semantically incorrect to type using uppercase characters in the markup.
