HTML5 <wbr> tag
The HTML5 <wbr> tag stands for word-break opportunity.
This informs the browser that this is the position within the text where the browser can optionally break the word to the next line.
Normally, this is used for a very long word. You can place the sub-string of that long word inside this tag so that the browser can think of breaking the word from that position if it is required to do so.
