当我垂直调整浏览器大小时,我无法弄清楚如何解决我的图像在屏幕上移动的问题。此外,不仅我的图像在屏幕上移动,而且我的横幅文本和背景也会四处移动,这导致横幅文本从横幅上移开。

最佳答案

横幅的文本没有相对于屏幕移动,但灰色背景在移动,因为您将其设置为屏幕高度的 25%。当您调整窗口的高度时,横幅也会相应调整。只需完全删除 height 属性即可。删除行高并设置 padding-top。将横幅设置为相对位置,因为它会覆盖表单。

添加

#form {
display: table;
margin: 0 auto;
}

并将表单的 div 更改为该 ID。删除你放在 body 和 html 中的 table-cell table-display。

将#imagesMain 更改为 position: relative。

工作解决方案:

#form {

编辑:编辑代码以在页面中间制作表单并将图像放在页面底部(它们会随着调整大小而移动)。
