标题不断移动到导航栏（引导程序）答案

【问题标题】：Title keeps shifting into the navigation bar(Bootstrap)标题不断移动到导航栏（引导程序）
【发布时间】：2017-07-18 03:33:39
【问题描述】：

我有一个导航栏，在其上方导航栏正下方的图像前面有一些文字。此图像是响应式的，因此它会根据屏幕大小进行缩放。但是，当我将屏幕调整到最小尺寸（即，如果它在移动设备上的尺寸）时，图像会停留在一个地方，但通常固定在图像前面的文本会向上推，导航栏后面。你能帮忙解释一下这是为什么吗？这是我的代码。

CSS

.navbar-brand {
    position:relative;
    bottom:70px;
    text-align:right;  
}

.image {
    position:relative;
    width:100%;
    padding-top:0;
    height:200px;
}

.text {
    text-align:center;
    position:relative;
    bottom:400px;
    color:white; 
    font-family:;

}

非常感谢，如果有不清楚的地方，请告诉我。

【解决方案1】：

由于底部：400px，文本推到导航栏后面；关于.text类的问题

您需要一些 HTML 和 CSS 修复
