HTML/CSS 背景图像仅显示所用图像的一部分
正如标题所说， 我目前正在建立一个网站，我对此很陌生，并且正在努力快速学习。然而，这个问题非常令人沮丧，因为我访问的网站没有帮助。
所以目前我有一个分辨率足够高的图像，它应该很容易填满屏幕。然而，当我加载 HTML 时，图像会在右上角放大，这是唯一可见的部分。我尝试过使用“高度”和“宽度”命令。我也尝试过没有它们。我尝试使用
另一点是，当我使用
As the title states,
I am currently building a website, I am new to this and am trying to learn quickly. However this problem is quite frustrating as websites I have gone to do not help.
So at the moment I have an image that is of a high enough resolution that it should fill the screen easily. However when I load the HTML the image is zoomed in on the top right corner which is the only part visible. I have tried using "height" and "width" commands. I have also tried without them. I have attempted to use a <div> and <body>. However this problem still persists.
Another point is that when I use a <div> the whole screen is not filled, it still has a white border around what I believe is the <div>.

You need this CSS to remove the default

OK, I would suggest you to make the width and height not in px but in % and secondly try setting the image using CSS
