            <p>The default REM (root em) size in Spectre.css is <code>20px</code>.</p>
            <p>Please note in the Chinese/Japanese/Korean version, Chrome uses 12px as default minimum font size. That is why Spectre sets rem default html font size to <code>20px</code>, which is relatively easy to calculate.</p>
            <p>Spectre uses <code>4px</code> as the unit size
