【问题描述】：

我正在设计一个标题，我的文本 div 正在向下移动。

HTML：

<!doctype HTML>
<html lang = "en-AU">
    <head>
        <title>Simon Teacher Search</title>
        <meta charset = "UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <base href="../">
        <link rel="stylesheet" type="text/css" href="CSS/desktop.css">
    </head>
    <body>
        <div id = "body-container">
            <header id = "header">
                <div id = "header-content">
                    <div id = "logo-container">
                        <img src = "Images/SHCK Logo.png" alt = "SHC Logo">
                    </div>
                    <div id = "header-text-container">
                        <div id = "header-text-top-container">
                            <span id = "SACRED-HEART-COLLEGE">SACRED HEART COLLEGE</span>
                            <span id =""></span>
                        </div>
                        <div id = "header-text-bottom-container">
                            <span id = "Kyneton">Kyneton</span>
                        </div>

                    </div>
                </div>
            </header>
        </div>
    </body>
</html>

CSS：

    /*Code written by Oliver Murfett and Caelan Grgurovic 2015

/*The following are classes that can be added to tags to give them certain features*/

.italics, i, em {
    font-style: italic;
}

.bold, b, strong {
    font-weight: bold;
}

.underline, u {
    text-decoration: underline;
}

.hidden {
    display: none;
}

/*Fonts*/
@font-face {
    font-family: "Open Sans-Regular";
    src: url(Fonts/OpenSans-Regular.ttf);
}

@font-face {
    font-family: "Trajan Pro Regular";
    src: url(Fonts\Trajan Pro Regular.ttf);
}
/*The following styles are to the maximize page space*/
html, body {
    width: 100%;
    margin: 0px;
    padding: 0px;
    background-color: white;
    top: 0px;
    height: 100%;
    min-height: 100%;
}

#body-container {
    width: 100%;
    margin: 0px;
    padding: 0px;
    top: 0px;
    height: 100%;
    min-height: 100%;
}

header {
    width: 100%;
    margin: 0px;
    padding: 0px;
    top: 0px;
    height: 100px;

}

/*The following styles are to style the header*/

#header-content {
    width: 100%;
    margin: 0px;
    padding: 10px;
    -webkit-box-sizing: border-box; 
    -moz-box-sizing: border-box;   
    box-sizing: border-box;    
    height: 100%;
    min-height: 100%;
}

#logo-container {
    height: 100%;
    min-height: 100%;
    display: inline-block;
    margin-right: 20px;
}

#logo-container img {
    height: 100%;
    min-height: 100%;
}

#header-text-container {
    height: 100%;
    min-height: 100%;
    top: 0;
    display: inline-block;
    margin-top: 0px;

}

#header-text-top-container {
    height: 50%;
    min-height: 50;
}

#header-text-bottom-container {
    height: 50%;
    min-height: 50;
}

#SACRED-HEART-COLLEGE {
    font-family: "Trajan Pro Regular";
    font-size: 34px;
    color: rgb(30,30,117);
}

这里的所有代码：http://jsfiddle.net/j5kcfwLa/

现在我的问题是：#header-text-container div 正在向下移动，而不是停留在顶部。我试过top: 0;，它什么都不做，position: absolute，它制造了不必要的机会。如何将此容器强制到其父容器的顶部？

【问题讨论】：

你为什么不试试这样jsfiddle.net/j5kcfwLa/2
@Oliver Murfett 您刚刚错过了在以下选择器 #header-text-bottom-container { height: 50%; 50 之后应用 'px' 或 '%'最小高度：50； }

标签： html css

【解决方案1】：

改变这个：

#SACRED-HEART-COLLEGE {
    font-family:"Trajan Pro Regular";
    font-size: 24px;
    color: rgb(30, 30, 117);
}

到这里：

#SACRED-HEART-COLLEGE {
    font-family:"Trajan Pro Regular";
    font-size: 24px;
    color: rgb(30, 30, 117);

    position: absolute;
    top: 0;
}

@欢迎您。如果这是您正在寻找的答案，请将问题标记为已解决

【解决方案2】：

如果你想达到用户所说的那样，那么你可以尝试添加

#SACRED-HEART-COLLEGE {
    font-family: "Trajan Pro Regular";
    font-size: 24px;
    color: rgb(30,30,117);
    line-height: 0;
    display: block;
}

嘿，你想达到这个目的吗？
