 == Elements of a regular expression ==
-* Anchors: Assert the start and end position of a line. ^ (caret) matches the start and $ (dollar sign) matches the end.
+=== Literal characters ===
-* Character class: Enclosed in square brackets [ ], defines a set of characters to match. For example, [aeiou] matches any vowel.
+Most characters simply match themselves. The letter '''a''' matches the letter "a" in the text.
-* Capturing group: Parentheses ( ) are used to create groups, used to treat multiple characters or subpatterns as a single unit.
-* Quantifiers: Specify the number of occurrences of the preceding character, character class or group. Common quantifiers include * (zero or more), + (one or more), ? (zero or one), and {} (exact number or range).
+=== Anchors (position markers) ===
-* Alternation: | (pipe). It allows you to specify alternatives, matching either the pattern on the left or the one on the right.
+Anchors do not match a character, they match a ''position'' in the text.
-* Negation: ^ (caret). Used inside a character class. Matches any character not listed in the character class. [^aeiou] matches any character that is not a vowel.
+* <code>^</code> (caret) — matches the start of a line.
-* Escape character: \ (backslash). It is used to escape a special character, allowing you to match it as a literal. Also used for encoded characters, e.g. \x20 matches a white space character.
+* <code>$</code> (dollar sign) — matches the end of a line.
-* Special character: . (dot) matches any character except new line, \w matches any word character, \d matches any digit, \s matches any whitespace character.
+* <code>\b</code> — matches a word boundary (the position between a word character and a non-word character).
