If you need to have a more precise presentation of your text (justified) in your webpage, you can use the hyphens:
You can put it in words to indicate to browsers that they can, if necessary, cut these words to where you put it.
When the browser will make the cut, a hyphen will be displayed and after the word sent to the line.
Otherwise, any dashes appear and the word will be seamless.
