<title>CSS Flexbox: large flex-shrink value</title>

<style>
.flex {
display: inline-flex;
width: 40px;
height: 40px;
}
.fractional {
height: 50px;
width: 50.5px;
min-width: 50.5px;
}
.high-shrink {
flex-shrink: 130000000000000;
height: 40px;

<div class="flex">
<div class="fractional"></div>
<div class="high-shrink"></div>
</div>
<p>The high flex shrink factor can lead to loss of precision as we calculate the
<a href="https://drafts.csswg.org/css-flexbox/#scaled-flex-shrink-factor">sum of
scaled flex shrink factors</a> as required by the spec, and as we later subtract
the scaled flex factors for frozen violations, we can get to a negative value
due to that lost precision.</p>
