如何防止用户在我的网站上调整字体大小？

document.addEventListener('DOMContentLoaded', function () {
  const fontSizes = ['12px', '14px', '16px', '18px', '20px'];
  const fontSizer = document.createElement('style');
  document.head.appendChild(fontSizer);
  
  for (let i = 0; i < fontSizes.length; i++) {
    const fontSize = fontSizes[i];
    fontSizer.textContent = `
      @font-face {
        font-family: 'YourFontFamily';
        src: url('https://example.com/fonts/yourfont.woff2') format('woff2'),
             url('https://example.com/fonts/yourfont.woff') format('woff');
      }
      body {
        font-size: ${fontSize};
      }
    `;
  }
  
  document.addEventListener('mousemove', function (event) {
    const target = event.target;
    if (target.tagName === 'BODY') {
      const mousePosition = {
        x: event.clientX,
        y: event.clientY
      };
      
      for (let i = 0; i < fontSizes.length; i++) {
        const fontSize = fontSizes[i];
        const sizeValue = getComputedStyle(document.body).getPropertyValue('font-size');
        const rect = target.getBoundingClientRect();
        const mouseDistance = getDistance(mousePosition, { x: rect.left, y: rect.top });
        if (mouseDistance < 100) {
          if (window.getComputedStyle(target).getPropertyValue('font-size') === sizeValue) {
            return;
          }
          target.style.fontSize = `${fontSize}px`;
          target.style.fontSize = `${fontSize}px`;
        }
      }
    }
  }, false);
});

function getDistance(p1, p2) {
  return Math.sqrt(Math.pow(p2.x - p1.x, 2) + Math.pow(p2.y - p1.y, 2));
}
