<h2>CSS</h2>

<p>For this, you'll want to use some new and mostly unsupported elements in your CSS to achieve the effect you want.</p>

<p>These two elements are</p>

<ul>
<li><a href="http://caniuse.com/#feat=css-shapes" rel="nofollow"><code>shape-outside</code></a></li>
<li><a href="http://caniuse.com/#feat=css-clip-path" rel="nofollow"><code>clip-path</code></a></li>
</ul>

<p>Please note, this does not work on FF as requested but I reckon it won't be too far off.</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>.mainDiv {
  width: 600px;

<h2>SVG</h2>

<p>The best way to guarantee that your page works across all browsers would probably be to use an SVG. This is the sort of animation you're looking for.</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;svg viewbox="0 0 100 100" width="20%"&gt;
  &lt;path id="square" d="M0,0 L100,0 L100,100 L0,100z" fill="#e3f5f1"&gt;
    &lt;animate attributeName="d" attributeType="XML" begin="mouseover" dur="1s" to="M0,0 L100,50 L100,50 L0,100z" fill="freeze" /&gt;
    &lt;animate attributeName="d" attributeType="XML" begin="mouseout" dur="1s" to="M0,0 L100,0 L100,100 L0,100z" fill="freeze" /&gt;
  &lt;/path&gt;
&lt;/svg&gt;</code></pre>
</div>
</div>
</p>


<p>I am trying to achieve the following animation on the text of a paragraph : </p>

<p><a href="https://i.stack.imgur.com/i3vDl.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/i3vDl.gif" alt="paragraph animation : changing the shape of the text"></a></p>

<p>The aim is to <strong>animate the boundaries of the text</strong> according to the shape on the left. This is what I have tried but I can't figure out the transition on the text shape :</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>.mainDiv {
  width: 600px;
  margin: 0px auto;
  border: solid 1px #000;
  padding: 10px;
  min-height: 200px;
}
.element {
  width: 200px;
  height: 200px;
  background: #e3f5f1;
  float: left;
  margin-right: 5px;
}
.textElement {
  width: 395px;
  float: left;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="mainDiv"&gt;
  &lt;div class="element"&gt;&lt;/div&gt;
  &lt;div class="textElement"&gt;

<p>I don't have much knowledge of <em>CSS</em> transitions and animations, so I hope to get some help.</p>
