HTMLkódolás

HTMLkódolás, or HTML encoding, is the process of converting characters into a format that can be transmitted over the Internet. This is necessary because HTML, the standard markup language for creating web pages, uses specific codes to represent characters that cannot be directly displayed or transmitted. For example, the less-than symbol (<) is used to denote the beginning of an HTML tag, so it must be encoded to be displayed as text on a web page.

The most common method of HTML encoding is to use character references, which are numerical or named codes that represent specific characters. Numerical character references use the format &# followed by a number, while named character references use the format & followed by a name and a semicolon. For example, the less-than symbol can be encoded as either &#60; or &lt;.

HTML encoding is essential for ensuring that web pages are displayed correctly and that data is transmitted accurately. It is used in a variety of contexts, including the encoding of special characters in URLs, the encoding of data in HTML forms, and the encoding of data in JavaScript. By using HTML encoding, web developers can ensure that their web pages are compatible with a wide range of browsers and devices, and that data is transmitted securely and accurately.
