Bootstrap class . text-Justify 3 doesn’t line up without any previous inheritance

Question

I inserted a class in a div to justify the internal text but does not respect, and there are no inheritances of classes or higher level elements.

<div class='col-xs-12 col-sm-12 col-md-8 col-lg-6">
    <div class='text-justify'>
        Lorem ipsum is simply dummy text of the printing and typesetting industry. lorem ipsum has been the
industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and
scrambled it to make a type specimen book. it has survived not only five centuries... 
    </div>
</div>

Thus remaining:

And the Firefox element inspector output is like this:

element {
}
.text-justify {
    text-align: justify;
}
html, body, div, applet, object, iframe p, blockquote, a, abbr, acronym, address, big, cite, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed, figure, figcaption, footer, header, hgroup, menu, nav, output, ruby, section, summary, time, mark, audio, video {
    font-family: 'Lato', sans-serif;
    line-height: 21px;
    font-weight: normal;
    font-style: normal;
    font-size: 14px;
    opacity: 1;
    visibility: visible;
    font-variant-numeric: lining-nums;
    font-feature-settings: 'lnum';
    -moz-font-feature-settings: 'lnum=1';
}

I believe your mistake may be here <div class='col-xs-12 col-sm-12 col-md-8 col-lg-6"> Notice that you open with simple quotes ' and closes with double quotes "

See that below works correctly.

<link rel="stylesheet" type="text/css" media="screen" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />
  
  <div class="container">
    <div class="row">
<div class="col-xs-12 col-sm-12 col-md-8 col-lg-6">
        <div class='text-justify'>
