Text Block Justify Parapraph

give a custom-class to those text-block elements – f.e.: justified-textblock

#top .justified-textblock p {
  text-align:justify;
  -webkit-hyphens: auto;
  -ms-hyphens: auto;
  hyphens: auto;
    /*** new options for hyphens auto with less browser support 
    -webkit-hyphenate-limit-chars: auto 4;
    -ms-hyphenate-limit-chars: auto 4;
    hyphenate-limit-chars: auto 4;
    ****/
}

don’t know if those browser support prefixes are still in use ;)

but! the browser’s Justified Text setting may give unusual results, as it generally does not set any conditional word wrapping (including hyphens).

There was in former times there was Plugin : Hyphenator that can do a better job – but the plugin has been closed as of July 27, 2023

Maybe the plugin: wp-typography is a good alternative
