Simple Syntax

Rather than going with the "good" old fromUnit-to-toUnit(fromUnit) syntax this function set is based on toUnit(fromUnit) making it a lot shorter and less cumbersome to maintain – as shown below :-)

       pt-to-px(input);
       pc-to-px(input);
       mm-to-px(input);
       cm-to-px(input);    ==>   px(input);
       in-to-px(input);
       em-to-px(input);
       rem-to-px(input);
       num-to-px(input);

Note!

• In this library, num means pure numbers.(10 => :o:, 10px => :x:)

• To allow conversion between relative and absolute lengths em and rem are calculated as pixel values based on $root-font-size and $base-font-size (16px browser default). If you change the base font size of your document – remember to set the $root-font-size and $base-font-size variables accordingly.

• To ease the job of handling compounds the em function takes multiple arguments. Each argument is treated as an em compound and used to calculate the visual size. Example – how to set a visual size of 18px on a class nested in an element with a font-size of 2em:

      .class {
          font-size: em(18px 2em); //  0.5625em;
      }

• If you use unit conversion in relation to the font shorthand syntax be aware that line-height "/" will cause division. To prevent this from happening you can either either interpolate the value or use + to add the pieces together without calculation:

      h2 {
          font:300 #{em(24px)}/3 'Lato', sans-serif;
      }

• $widthvw's basis, break-width, $break-heightvh's basis, break-height are conditional arguments used when vw($break-width), vh($break-height), vmin($break-width, $break-height), vmax($break-width, $break-height).

      h2 {
          font-size: vw(18px,  $width: 1200px);  // 1.5vw
          font-size: px(1.2vh, $height: 600px);  // 7.2px
          font-size: vmin(18px, 1200px, 600px);  // 3vmin
          font-size: vmax(1.2vh, 1200px, 600px); // 0.6vmax
      }

Check Unit

• You can check unit & types with is-[unit]($input)

• Types: null, bool, color, list, map, color, calc, exist

• However, there is a strict mode for num, null, exist.(Default value is true)

      is-px(16px);         // true;
      is-px(16pt);         // false;

      is-num(16,    true); // true;
      is-num(16px,  true); // false;
      is-num(16px, false); // true;

      is-null(null, true); // true;
      is-null((),   true); // false;
      is-null('',   true); // false;
      is-null((),  false); // true;
      is-null('',  false); // true;

      is-exist($exist-var,  true); // true;
      is-exist($true-var,  false); // true;
      is-exist($false-var, false); // false;

• is-equal($inputA, $inputB): Checks if two values are equal.
