11.24.1. HTML entity ¶

In HTML, some characters are reserved.

The less than sign (<) and the greater than sign (>) cannot be used in HTML because browsers mistook them for tags.

If we want to display reserved characters correctly, we must use character entities (character entities) in the HTML source code. Character entities look like this:

& *entity_name*;
or
&# *entity_number*;

To display the less than sign, we must write: < or < or <

Tip: the advantage of using entity names instead of numbers is that names are easy to remember. The downside, however, is that browsers may not support all entity names (entity numbers are well supported).

11.24.2. Non-breaking Space ¶

The common character entities in HTML are uninterrupted spaces (& nbsp;).

Browsers always truncate spaces in HTML pages. If you write 10 spaces in thetext, the browser deletes 9 of them before displaying the page. To increasethe number of spaces in the page, you need to use the & nbsp; character entity.

11.24.3. Combined phonetic alphabet ¶

A phonetic symbol is a “glyph” added to a letter.

Some consonant symbols, such as sharp notes and muted notes.

Consonant symbols can appear above and below the letter, or inside the letter, or between two letters.

Phonetic symbols can be used in combination with alphabetic and numeric characters.

Here are some examples:

11.24.4. HTML character entity ¶

Entity names are case sensitive!

Although html is not case-sensitive, entity characters are case-sensitive.
