Wrapping long text without white space inside of a div

white-space: pre-wrap

is what worked for me for <span> and <div>.

You can use the following

p{word-break: break-all;}

        <p>LoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolor</p>

You can't wrap that text as it's unbroken without any spaces. You need a JavaScript or server side solution which splits the string after a few characters.

EDIT

You need to add this property in CSS.

word-wrap: break-word;

I have found something strange here about word-wrap only works with width property of CSS properly.

#ONLYwidth {
  width: 200px;
}

#wordwrapWITHOUTWidth {
  word-wrap: break-word;
}

#wordwrapWITHWidth {
  width: 200px;
  word-wrap: break-word;
}

Here is a working demo that I have prepared about it. http://jsfiddle.net/Hss5g/2/
