当浏览器未最大化时，我的标题对齐。当我最大化它移动并且未对齐时。我怎样才能对齐它，使其永远不会移动。我希望它与其下方的其余内容位于完全相同的位置

CSS:

#header {margin-left:50px; align: center;
         }

#container {

     background-color: #FAFAFA;
     color: #003300;
     font-family: Arial, Helvetica, sans-serif; background-position: center; background-size: cover;

}

#h2 {text-align: center;}

#container {
          margin-right:auto;
          margin-left:auto;
          background-image:url('backgroundflower5.jpg');
          min-width:1000px;
          max-width:1000px;
          padding:0px 70px 50px 70px;
          border:1px ridge #000000;
          border-radius:20px;
          -webkit-box-shadow:inset -3px -3px -3px 3px #18cad0;
          -moz-box-shadow:inset -3px -3px 3px 3px #00332B;

            width: 960px;
            margin: 0 auto;
        }

        #container div {

最佳答案

您正在使用 margin-left:50px; 请改用 margin:0 auto;

#header {
    margin: 0 auto;
    width: 1150px;
 }

它做了什么 margin-left

所以它将离开浏览器 50px，并且在不同的宽度上它看起来会有所不同，所以更好的方法是使用 margin:0 auto;

margin:0 auto 总是居中
