TextOverflowStyle

This keyword value indicates to truncate the text at the limit of the content area, therefore the truncation can happen in the middle of a character. To truncate at the transition between two characters, the empty string value must be used. The value clip is the default for this property. --MDN

This keyword value indicates to display an ellipsis ('…', U+2026 HORIZONTAL ELLIPSIS) to represent clipped text. The ellipsis is displayed inside the content area, decreasing the amount of text displayed. If there is not enough space to display the ellipsis, it is clipped. --MDN

The inherit CSS keyword causes the element for which it is specified to take the computed value of the property from its parent element. --MDN

The initial CSS keyword applies the initial (or default) value of a property to an element. --MDN

The revert CSS keyword reverts the cascaded value of the property from its current value to the value the property would have had if no changes had been made by the current style origin to the current element. --MDN

The unset CSS keyword resets a property to its inherited value if the property naturally inherits from its parent, and to its initial value if not. In other words, it behaves like the inherit keyword in the first case, when the property is an inherited property, and like the initial keyword in the second case, when the property is a non-inherited property. --MDN
