1. 가로 중심 설정 - 인라인 요소

상위 요소를 통해 1 text-align:center;을 설정하여 상위 요소의 콘텐츠를 중앙에 배치합니다.

2. 가로 중심 설정-고정폭 블록 요소

블록 요소의 너비는 고정된 값이며, "왼쪽 및 오른쪽 여백" 값을 "auto"로 설정하면 중앙에 위치한

을 구현할 수 있습니다.

예: 

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>定宽块状元素水平居中</title>
<style>
div{
    width: 200px;/*固定的宽度*/
    margin: 20px auto;/*左右margin设置为auto*/
    border: 1px solid red;
}
</style>
</head>
<body>
<div>我是定宽块状元素，我要水平居中显示。</div>
</body>
</html>

3. 가로 중심 설정 - 가변 폭 블록 요소

방법 1. table 태그

추가
