我有一个导航栏，我有一些文本直接位于图像前面导航栏上方的正下方。此图像是响应式的，因此它会根据屏幕的大小进行缩放。但是，当我将屏幕调整到最小尺寸(即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，在导航栏后面。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:;
font-size:24px;
}
非常感谢，如果有任何不清楚的地方，请告诉我。
最佳答案
由于 bottom:400px，文本推到导航栏后面； .text 类的问题
