<p>That's a strange behavior. Even I'm looking for technical reason behind it. </p>

<p>For the time-being you can remove the scrollbar - by making two changes:</p>

<ol>
<li>remove <code>display: inline-block;</code> from <code>.svg-container</code> class</li>
<li>Add <code>float:left</code> to <code>SVG</code> element. or <code>display</code> also works.</li>

<p>The SVG element is vertically positioned at baseline. That's why it's taking 4px extra space at the bottom of it. Just tell it to get vertically aligned at the top and you will get the desired result. Just change you css from</p>

</div>
</p>

<p>As I see, the scroll appears, because there is extra space below <em>svg-container</em> div. But changing display, as was suggested in other posts, has no effect.</p>

<p><strong>Extra considerations:</strong></p>

<ul>
<li>I don't want to change styles for <em>widget-outer</em> and <em>widget</em> classes, because they are working fine for other widgets. <strong>overflow-y: auto</strong> on <em>widget</em> class is required, becuase some other widgets have longer content that should be scrollable.</li>
<li>I want <em>svg</em> element to take all available space in <em>widget</em> for any combination of height and width on <em>widget-container</em>.</li>
<li>Decreasing <strong>max-height</strong> of <em>svg</em> element is helping, but can not be counted as proper solution to this problem.</li>
</ul>

<p>tl;dr Is it possible to fit <em>svg</em> in <em>widget</em> without scrollbar?</p>


Child is same size as parent, but scroll appears
