This looks pretty good to me      A common problem when creating dynamic   web pages  where content is sourced   from a database  content management   system or external source such as an   RSS feed  is that the input text can   be too long and cause the page layout   to  break        One solution is to truncate the text   so that it fits on the page  This   sounds simple  but often the results   aren t as expected due to words and   sentences being cut off at   inappropriate points
