我有一个将包含此CSS的div:
#some_kind_of_popup
{
position: fixed;
top: 100px;
min-height: 300px;
width: 90%;
max-width: 900px;
}
Now, how can i make this div centered? I can use margin-left: -450px; left: 50%;
but this will only work when the screen is > 900 pixels. After that (when the window is < 900 pixels), it will no longer be centered.
我当然可以用某种js来实现这一点,但是用CSS来实现这一点"更正确"吗?
