<hr>
<div class="content">
<p>Bulma uses 5 custom functions to help define the values and colors dynamically:</p>
<ul>
<li><code>powerNumber($number, $exp)</code>: calculates the value of a number exposed to another one. Returns a number.</li>
<li><code>colorLuminance($color)</code>: defines if a color is dark or light. Return a decimal number between 0 and 1 where <= 0.5 is dark and > 0.5 is light.</li>
<li><code>findColorInvert($color)</code>: returns either 70% transparent black or 100% opaque white depending on the luminance of the color.</li>
<li><code>removeUnit($number)</code>: removes the unit of a Sass number. So "10px" becomes "10" and "3.5rem" returns "3.5". Used for string concatenation.</li>
<li><code>roundToEvenNumber($number)</code>: rounds a number to the closest but lower even one. So 23 becomes 22, and 7.5 returns 6.</li>
</ul>
