A sewing page that never closed its font size HTML tags
nested H3 tags with:<p><pre><code>    h3 {
        font-size: 1.17em;
</code></pre>
"(historically the em unit was derived from the width of a capital "M" in a given typeface.). The numeric value acts as a multiplier of the font-size property of the element on which it is used."<p>So this used to work and look normal.
