how to remove white space in justified css

If I am using
text-align:justify
paragraph shows unwanted space between words to maintain specified width. Searched in internet but didn't get any proper result. I used white-space also but no use

fiddle :fiddle

Solution

The closest solution would be using word-break: break-all but this will also break words. If you are ok with this then go with this solution:

.sample_test p{
    word-break: break-all;
}

Edit (Nov, 2021)

Other closest better solution is using hyphens: auto. We have to mention the global attribute lang to the HTML element to make this work:

.sample_test {
  display: block;
  margin: 0 auto;
  width: 400px;
  height: auto;
}

.sample_test p {
  /* word-break: break-all; */
  hyphens: auto;
}

<div class="sample_test" lang="en">
