/*CSS*/. P{width:200px;Word-break:Break-all;Text-overflow:ellipsis;Display:-webkit-box;/** Object as Telescopic box model display **/-webkit-box-orient:Vertical;/** Set or retrieve the arrangement of child elements of a telescopic box object **/-webkit-line-clamp:2;/** Number of lines displayed **/Overflow:Hidden;/** Hide beyond the content **/}

1,word-break:break-all such as a div width of 200px, its content will go to 200px word wrap, if the end of the line has a long English words (congratulation, etc.), it will truncate the word, to the end of the line is Conra ( Congratulation), the backend portion of the next behavior tulation (conguatulation).
2,word-wrap:break-word example is the same as above, but the difference is that it will congratulation the whole word as a whole, if the line end width is not enough to display the whole word, it will automatically put the whole word to the next line, not the word truncated.
