A non-breaking space is a white space character that HTML will not collapse.
Non-breaking spaces are used to hold open table cells and add spacing between words. It is also common to use non-breaking spaces to add tabs to HTML or to indent the first line of a paragraph.
Many of the ways non-breaking spaces are used can be done using the CSS properties margin and padding. You can also affect the white space of your web pages with the white-space property.
