How to fit a paragraph inside a css polygon

Question

I have been able to successfully use shape-outside: polygon(...) and clip-path: polygon(...) to create a desired polygon shape.

I have seen many pages referencing use of shape-inside, and yet I have read that shape-inside had been deprecated and has no replacement. They were also written in 2014, so I am hoping that CSS3 has changed since then.

After looking on the web, I was able to piece together something that almost works. I like the shape, but now I need the text wrap inside the shape with the overflow hidden.

I have seen hints about ::before, but I still don't understand how that would help. Testing it didn't seem to produce any results.

Whether it's simple or complicated, how can I use CSS to wrap the text within the polygon? Or does the solution lie outside of CSS? Do I need to use another approach, like jQuery?

CSS

/*
For reference:    
@vertex1: 120px;
@vertex2: @vertex1*2;
*/

.diamondContainer {
    display: block;    
    position: absolute;
    text-align: center;
    width: @vertex2;
    height: @vertex2;
    overflow: hidden; /* hide anything longer than allowed string length */

    /* This is a diamond shape */    
    shape-outside: polygon(@vertex1 0, @vertex2 @vertex1, @vertex1 @vertex2, 0 @vertex1);    
    clip-path: polygon(@vertex1 0, @vertex2 @vertex1, @vertex1 @vertex2, 0 @vertex1);
}

HTML

<div class="diamondOuter">
    <div class="diamondWrapper">
        <div class="diamondContainer diamondCell2">
            <span><strong>Title Text</strong><br />Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.

        </div>
    </div>
</div>

Look again at shape-outside.

You don't set it on the text container, but other elements around the text.

In your case, you may need to have at least 2 div's for the text to flow around.

There is an example of text flowing between 2 polygons on this page.
