html - 如何让这个段落元素向上 move ？

Question

我已经把这一切都写出来了，除了最后的

元素外，一切都很完美。我想将它向上 move 到由类为“defaultButtonStyle”的 div 创建的蓝色矩形的中心。我试过在 css 中使用 margin-top 无济于事。您还有其他想法吗？

<style>
body {background-color: #ebf0f3;}
.mainPicture img {height: 400px;
    width:600px; }
#gallery {position: relative; }
#gallery ul {list-style-type: none;
    width: 236px; 
    margin-left: -33px;
    margin-top: -15px; }
#gallery li { display: inline; 
     float: left;
     padding: 0px; }
#gallery img {border-style: solid: 10px; border-color: #ebf0f3; }
#gallery a { text-decoration: none;
             font-style: none;  
             color: #333; }
.popOut {cursor: default;
    list-style: none; }
.popOut a {cursor: default; }
.popOut a .preview {display: none; }
.popOut a:hover .preview {display: block;
    position: absolute;
    top: -20px;
    left: -45px;
    z-index: 1; }
.popOut img {background: #ebf0f3;
    border-color: #ebf0f3;
    border-style: solid;
    border-width: 2px;
    color: inherit;
    vertical-align: center;
    width: 100px;
    height: 67px; }
.popOut li {background-color: none;
    border-color: #ebf0f3;
    border-style: solid;
    border-width: 0px;
    color: inherit;
    display: inline;
    float: left;
    margin: 3px;
    padding: 0px;
    position: relative; }
.popOut .preview {border-color: #000;
    width: 200px;
    height: 134px; }
.popOut p {text-align: center; }
.defaultButtonStyle {background: #ebf0f3;
    border-color: #ebf0f3;
    border-style: solid;
    border-width: 1px;
    color: inherit;
    vertical-align: top;
    width: 212px;
    height: 38px;
    margin-top: -43px;
    text-align: center; }
.defaultButtonStyle p .defaultImageText {top-margin: 100px; }
.popOut .center {align: center; }
#rightcol {margin-left: 237px;}
#rightcol .fixThisHeight {
    margin-top: 18px; }

<p>Just some text</p>

Answer 1

老实说，我还没有找到解决方案，因为我不太明白你想要什么元素在哪里......而且图像无法显示，因为它们链接到未知来源。

但是，您的 margin 无法通过的原因之一可能是因为它不应该

.defaultButtonStyle p .defaultImageText *{top-margin: 100px; }*

应该是

.defaultButtonStyle p .defaultImageText {margin-top: 100px; }

试一试。
