    <h2>Variations</h2>
    <h1>Metamorphosis in Type Design</h1>
    <p>Variable font design is a biological process by which a typeface physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the structure of the glyphs through cell growth and differentiation. Some historical
      styles can undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Glyphs that go through metamorphosis are called variable. Typefaces can be divided into styles that undergo complete metamorphosis, incomplete
      metamorphosis, or no metamorphosis.
