This article will introduce some common HTML character entities

We know that in HTML certain characters are reserved and cannot be used directly

For example, if you enter multiple consecutive Spaces in HTML, you may end up with only one space

If we want to display reserved characters correctly, we must use character entities in our HTML source code

Some commonly used character entities are listed below, which are recorded here for future reference
