CSS中可以使用repeat屬性在x軸上重復圖案或背景，以下是一些示例代碼：

示例1：背景圖案的x軸重復

.pattern-repeat {
  background-image: url('pattern.png');
  background-repeat-x: repeat;
}

示例2：背景顏色的x軸重復

.color-repeat {
  background-color: #333;
  background-repeat-x: repeat;
}

示例3：邊框圖案的x軸重復

.border-pattern {
  border: 10px solid transparent;
  border-image: url('pattern.png') repeat;
}

示例4：列表項目的x軸重復

.list-repeat {
  list-style-image: url('pattern.png');
  list-style-position: inside;
}

示例5：漸變背景的x軸重復

.gradient-repeat {
  background: linear-gradient(to right, #333, #666);
  background-repeat-x: repeat;
}

示例6：陰影效果的x軸重復

.shadow-repeat {
  box-shadow: 10px 0 5px rgba(0, 0, 0, 0.5);
  transform: translateX(-10px); /* 修正陰影位置 */
}

示例7：動畫效果的x軸重復

.animation-repeat {
  animation: moveLeft 5s linear infinite;
}
@keyframes moveLeft {
  0% { transform: translateX(0); }
  100% { transform: translateX(-100px); }
}

示例8：響應式設計的x軸重復

@media (min-width: 600px) {
  .responsive-repeat {
    background-image: url('pattern.png');
    background-repeat-x: repeat;
  }
}
