La propiedad de CSS text-overflow determina como el contenido que se desborda y que no es mostrado, va a hacersele notar a los usuarios. Puede ser cortado, mostrar una elipsis ('', U+2026 Horizontal Ellipsis), o mostrar una cadena de texto personalizada.

La propiedad text-overflow no forza a que ocurra un desbordamiento. Para hacer que un texto desborde a su contenedor debes poner algunas otras propiedades de CSS. Por ejemplo:

overflow: hidden;
white-space: nowrap;

The text-overflow property only affects content that is overflowing a block container element in its inline progression direction (not text overflowing at the bottom of a box, for example).

Syntax

The text-overflow property may be specified using one or two values. If one value is given, it specifies overflow behavior for the end of the line (the right end for left-to-right text, the left end for right-to-left text). If two values are given, the first specifies overflow behavior for the left end of the line, and the second specifies it for the right end of the line.

Each value is specified as one of:

Values

clip
The default for this property. This keyword value will truncate the text at the limit of the content area, therefore the truncation can happen in the middle of a character. To clip at the transition between characters you can specify text-overflow as an empty string, if that is supported in your target browsers: text-overflow: '';.
ellipsis
This keyword value will 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.
<string>
The <string> to be used to represent clipped text. The string is displayed inside the content area, shortening the size of the displayed text. If there is not enough space to display the string itself, it is clipped.
fade
This keyword clips the overflowing inline content and applies a fade-out effect near the edge of the line box with complete transparency at the edge.
fade( <length> | <percentage> )
This function clips the overflowing inline content and applies a fade-out effect near the edge of the line box with complete transparency at the edge.
The argument determines the distance over which the fade effect is applied. The <percentage> is resolved against the width of the line box. Values lower than 0 are clipped to 0. Values greater than the width of the line box are clipped to the width of the line box.

Formal syntax

[ clip | ellipsis | <string> ]{1,2}

Examples

CSS

p {
  width: 200px;
  border: 1px solid;
  padding: 2px 5px;

  /* BOTH of the following are required for text-overflow */
  white-space: nowrap;
  overflow: hidden;
}

.overflow-visible {
  white-space: initial;
}

.overflow-clip {
  text-overflow: clip;
}

.overflow-ellipsis {
  text-overflow: ellipsis;
}

.overflow-string {
  /* Not supported in most browsers, 
     see the 'Browser compatibility' section below */
  text-overflow: " [..]"; 
}

A previous version of this interface reached the Candidate Recommendation status. As some not-listed-at-risk features needed to be removed, the spec was demoted to the Working Draft level, explaining why browsers implemented this property unprefixed, though not at the CR state.

1. Until Firefox 10, handling of text-overflow on blocks with inline overflow on both horizontal sides was incorrect. Before Firefox 10, if only one value was specified (such as text-overflow: ellipsis;), text was ellipsed on both sides of the block, instead of only the end edge based on the block's text direction.
