word-wrap/break word in Chrome fails.

The CSS is still applying in Chrome. In the bigger picture what is the issue?

The problem is, in Chrome, words in the main articles are not break-
ing up <- like this.

I’m not seeing this issue in Chrome on the page you linked, sorry. Try clearing your cache.

I made a printscreen of the problem:

Is this the same word-wrap as you see in Chrome?

Have you added this stuff

-webkit-hyphens: auto;
   -moz-hyphens: auto;
    -ms-hyphens: auto;
        hyphens: auto;

Yes sir, this is the complete code. Added it now but it won’t work.

.site-content article {
	border-bottom: 4px double #ededed;
	margin-bottom: 72px;
	margin-bottom: 5.142857143rem;
	padding-bottom: 24px;
	padding-bottom: 1.714285714rem;
	word-wrap: break-word;
	-webkit-hyphens: auto;
	-moz-hyphens: auto;
	-ms-hyphens: auto;
	hyphens: auto;
}

Odd, it may be a general problem rather than a WordPress one, have you tried googling for this? E.g.: https://kenneth.io/blog/2012/03/04/word-wrapping-hypernation-using-css/

Tried some, but didn’t work.

Found this though:

Is it really impossible to hyphenate is Chrome?
