# HTML Text Formatting Examples This is a **bold (b)** example and right next to it we have a **strong emphasis (strong)** . Notice that **strong + bold mixed** looks similar but carries additional semantic meaning. Here is an *italic (i)* word and an *emphasis (em)* example. Sometimes we combine them like *italic + emphasis together* . Now let's look at text that appears crossed out: ~~strikethrough with s~~ and ~~deleted with del~~ . You can also mix them: ~~double strikethrough (s + del)~~ . To highlight insertions or underlines: underlined with u , inserted with ins . A combination could be: underline + insertion together . Subscript and superscript examples: Water is written as H 2 O using sub. The mathematical expression x 2 + y 3 uses sup. They can also be combined: CO 2 * . Mixing several: This sentence has ***strong + emphasis*** , some **bold + underline** , and a formula like a 2 + b 3 .
