What are the commonly used HTML escape characters?

HTML escape characters refer to some characters that have special meanings or are specified as special characters. Some special escape characters need to be used in HTML documents. Commonly used HTML escape characters are as follows:

1. < represents the less than symbol (<).
2. > represents the greater than symbol (>).
3. & represents the symbol &.
4. ' represents a single quote (').
5. " means double quotes (").

These special characters are very commonly used in HTML, so special escape characters need to be used to represent them to avoid causing semantic problems in HTML documents. For example, if you need to use the symbol < in an HTML document, you can replace it with <, which prevents the browser from interpreting it as the beginning of an HTML tag.

In addition to the above commonly used HTML escape characters, there are some other escape characters, as follows:

1. ' represents a single quote (').
2. " means double quotes (").
3. < means less than sign (<).
4. > means greater than sign (>).

5. & represents the symbol &.

These escape characters can be represented by their corresponding ASCII codes, and their usage is similar to commonly used HTML escape characters.

It should be pointed out that you need to be careful when using HTML escape characters. If the escape characters are used improperly, it may cause encoding problems. For example, when using special characters in an HTML document encoded with UTF-8, you need to note that since UTF-8 uses multiple bytes to represent a character, you need to use the correct escape character to represent the special character. , otherwise it may cause parsing errors and the page cannot be displayed correctly.

In short, HTML escape characters are very important when writing HTML documents. They can help us correctly represent some special characters, thereby preventing semantic problems and encoding problems. Developers who need to write HTML documents should keep them in mind during the writing process to avoid unnecessary errors.
