How to resolve a div in English that can't be wrapped automatically

In a div with a set width, when the length of Chinese text entered exceeds the set width, it will be automatically changed to the next line. However, if the input is the English letter, then, regardless of your div set width, the English letter is not wrapped directly in the same line output, resulting in the width of the div far beyond the set size.

Reason: This is because in Div, there is no space between the English letter, it will default to think that this is an English word, so the word output does not break line. So, do we have to add a space between each letter to solve the problem? In fact, can be implemented through CSS.

Workaround: Set Word-break:break-all in the style of the Div, and then wrap the line.
