A frequently utilized HTML entity is the non-breaking space:
A non-breaking space functions as a space that remains intact without causing a line break.
When two words are separated by a non-breaking space, they remain together without breaking onto a new line. This is particularly useful when separating the words might disrupt the flow of content.
Examples:
Another common application of the non-breaking space is to prevent browsers from trimming spaces in HTML pages.
For instance, if you include 10 spaces in your text, the browser will eliminate 9 of them. To retain actual spaces in your text, you can utilize the character entity.
The non-breaking hyphen (‑) is employed to designate a hyphen character (‑) that does not cause a line break.
