justify all text in Avenue theme

Hi there!

I'm trying to justify all text on my avenue theme. I've tried inserting some of the other codes offered to justify text, but nothing is happening... my site is www.bigfeelslab.com in case that's helpful.

thanks in advance for any insight!

past this code in custom css box

.sqs-block-html .sqs-block-content *:not(h1):not(h2):not(h3) {
   word-wrap: break-word;
   text-align: justify !important;
}
