February 17Feb 17 Administrators HTML Entities Reserved characters in HTML must be replaced with entities: < (less than) = < > (greater than) = > HTML Character Entities Some characters are reserved in HTML. If you use the less than (<) or greater than (>) signs in your HTML text, the browser might mix them with tags. Entity names or entity numbers can be used to display reserved HTML characters. Entity names look like this: &entity_name; Entity numbers look like this: &#entity_number; To display a less than sign (<) we must write: < or < Entity names are easier to remember than entity numbers. Non-breaking Space A commonly used HTML entity is the non-breaking space: A non-breaking space is a space that will not break into a new line. Two words separated by a non-breaking space will stick together (not break into a new line). This is handy when breaking the words might be disruptive. Examples: § 10 10 km/h 10 PM Another common use of the non-breaking space is to prevent browsers from truncating spaces in HTML pages. If you write 10 spaces in your text, the browser will remove 9 of them. To add real spaces to your text, you can use the character entity. The non-breaking hyphen (‑) is used to define a hyphen character (‑) that does not break into a new line.

Combining Diacritical Marks A diacritical mark is a "glyph" added to a letter. Some diacritical marks, like grave ( ̀) and acute ( ́) are called accents. Diacritical marks can be used in combination with alphanumeric characters to produce a character that is not present in the character set (encoding) used in the page.
