Bold formatting is probably the most common and effective way to make text stand out. For instance, browsers typically style the h1–h6 headings in bold by default. Just as with italics, you may style any text in bold or turn it off. Style sheets give you a lot of flexibility with bold text, providing relative values. However, the fonts themselves don’t always include different weights that map to the relative values, often making them look the same (when in doubt, just specify the weight as bold) ( and ).
