!important keyword must be space separated value try this;

#selector{
text-align:justify !important;
}

if you use this below, checkout specificity and cascade

#selector{
text-align:justify;
}

text-align works for all except for the block element whose width is set by user , for that u have to use margin:auto;

I have also tried this:

.align-justified {
text-align: justify!important;
}

Did not work either.

#selector {
text-align:justify;
}

But it does not work, what do I do wrong?

text-align: -moz-center;
text-align: -webkit-center;
margin: 0 auto;
