CSS (3) display ellipsis

You need to set the width to overflow display ellipses.
Single-line text:

. am-text-truncate {    word-wrap:normal;/* for IE */    text-overflow:ellipsis;    When text overflows, the ellipsis is displayed to represent the trimmed text.    White-space:nowrap;  The text in the specified paragraph does not wrap    Overflow:hidden;}

　　

Word-wrap:normal/break-word;
Normal wraps only at the allowed hyphenation points (the browser keeps the default processing).
Break-word line wrapping within a long word or URL address.

Multiple lines of text:

. am-text-truncate {    display:-webkit-box;    -webkit-box-orient:vertical;    -webkit-line-clamp:3;    Overflow:hidden;}

To set height to an integer multiple of line-height, prevent excess text from revealing.
