When writing HTML code, we need to set the encoding format of the file to ensure that the browser can correctly display the web page content. This article will introduce the encoding format of HTML and how to set it up.
Introduction to HTML encoding format
The encoding format of HTML web pages refers to the character encoding method used in HTML files. Common encoding formats include ASCII, GBK, UTF-8, etc.
ASCII (American Standard Code for Information Interchange) is the most basic character encoding method, used to represent English text characters. It contains 128 characters, including 26 uppercase letters, 26 lowercase letters, numbers, punctuation marks, and some special characters.
GBK (Guo Biao (National Standard) Kou Jian (Extended)) is a Chinese encoding format that contains all Chinese characters. GBK encoding includes GB2312 encoding and extended parts.
UTF-8 (Unicode Transformation Format 8-bit) is currently the most commonly used character encoding method. It supports characters in all languages, including various special symbols, expressions, etc. UTF-8 uses variable-length encoding and can handle any Unicode characters, so it is recommended by most web developers.
Set HTML encoding format
In the header declaration of the HTML document, we can specify the encoding format of the document. The following is an example:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>设置HTML编码格式</title> </head> <body> <!-- 这里是网页内容 --> </body> </html>
In the above example, we use the <meta> tag to set the encoding format, and its attribute charset specifies the The encoding used for the file is UTF-8.
Note: <meta>The position of the label is very important, it must be at the top of the header, otherwise unpredictable errors may occur.
In addition to using the <meta> tag, you can also specify the encoding format when the document is declared, for example:
<!DOCTYPE html> <html> <head> <title>设置HTML编码格式</title> </head> <body> <!-- 这里是网页内容 --> </body> </html>
In the above example, we omitted the <meta> tag, instead specify the encoding format as UTF-8 when the document is declared. This is also possible, but less common.
Summary
HTML encoding format refers to the character encoding method used in HTML files. Common encoding formats include ASCII, GBK, UTF-8, etc. When writing HTML code, we need to set the encoding format of the file to ensure that the browser can display the web page content correctly. We can use the <meta> tag or specify the encoding format when declaring the document. No matter which method is used, pay attention to the correctness of the encoding format to avoid problems such as garbled codes.
