white-space
CSS white-space Property
The white-space property specifies how the white space inside an element is handled. A white space can be a sequence of spaces or a line break.
This property can be applied to any inline content within an element.
Extra specified spaces are collapsed into one, newlines are removed, and lines are broken and wrap where necessary to fit inside their container.

Values
| Value | Description | Play it |
|---|---|---|
| normal | Breaks lines as necessary to fill line boxes. This is the default value of this property. | Play it » |
| nowrap | With this value the text will never wrap to the next line. | Play it » |
| pre | Allows to have extra spaces on the line before the first letter of the text. | Play it » |
| pre-line | Sequences of whitespace collapse into a single whitespace. Text will wrap when necessary, and on line breaks. | Play it » |
| pre-wrap | Whitespace is preserved by the browser. Text will wrap when necessary, and on line breaks. | Play it » |
| break-space | The same behavior as “pre-wrap” except: |
any sequence of preserved white space always takes up space, including at the end of the line a line breaking opportunity exists after every preserved white space character, including between white space characters such preserved spaces take up space and do not hang, and thus affect the box’s intrinsic sizes| |initial|Makes the property use its default value.|Play it »| |inherit|Inherits the property from its parents element.||
