 In order to force a web browser to display multiple spaces, a special character sequence must be used (such as "codice_1" for an en-space followed by a thin space, "codice_2" for an em-space, or "codice_3" for two successive full spaces).However, using a non-breaking space can lead to uneven justified text and additional unwanted spaces or line breaks in the text in certain programs.Alternatively, sentence spacing can be controlled in HTML by separating every sentence into a separate element (e.g., a span), and using CSS to finely control sentence spacing.
