    <h3 class="text-lg font-bold">ADA Tests Overview</h3>
    <p class="">ADAFontCheck perfoms the following tests:</p>
    <ul class="p-4 list-disc">
      <li>Character Stroke Width ratio using the uppercase letter 'I'.</li>
      <li>Character Body Width ratio using the uppercase letters 'I,' 'H,' and 'O'.</li>
      <li>Italic Font detection.</li>
      <li>Serif Font detection.</li>
      <li>Sans Serif Font determination.</li>
      <li>Fonts must meet the ratio requirements of both Tests 1 and 2 for ADA compliance.</li>
      <li>Numerals are not tested for compliance but are considered compatible when used with letters of the same font set and size.</li>
