Minimal styles for all HTML elements. Plus, it's adaptive to light and dark. The props are made available for you to continue building <a href="https://codepen.io/argyleink/pen/jOLaBgG">components</a> too.</p>
        <div>
          <h4>Included adaptive props</h4>
          <h3>4 Surface Colors</h3>
          <p>Great for cards, buttons, borders, sidenavs, wells, etc. When you want to change the perception of layering and grouping.</p>

            var(--text-2)
          </h5>
          <p>Using these props results in colors that adapt to the users system theme preference automatically.</p>
          <p>The brand color is used sparingly, find it used in the HTML elements below! The link color is useful for buttons and other custom components you want to have consistent interactive text for.</p>
