我发现以下 CSS 指令不会调整 IE9 中显示的 DIV 背景图像的大小。你有什么主意吗?
HTML:
<DIV id=window20 class="window smallWindow">
<STRONG>abcde</STRONG>
<BR /><BR />
</DIV>
CSS:
.window {
Z-INDEX: 20;
BORDER-BOTTOM: #346789 2px dotted;
POSITION: absolute;
BORDER-LEFT: #346789 2px dotted;
PADDING-BOTTOM: 0.5em;
PADDING-LEFT: 0.5em;
WIDTH: 14em;
PADDING-RIGHT: 0.5em;
FONT-FAMILY: helvetica;
HEIGHT: 4em;
COLOR: white;
FONT-SIZE: 1.0em;
BORDER-TOP: #346789 2px dotted;
BORDER-RIGHT: #346789 2px dotted;
PADDING-TOP: 0.5em;
border-radius: 0.6em;
-moz-border-radius: 0.6em
}
.smallWindow1 {
BACKGROUND-COLOR: #558822
}
#window20 {
TOP: 10em;
LEFT: 8em;
WIDTH: 8em;
HEIGHT: 4em;
background-image :url(../image/interface_system.png);
background-repeat: no-repeat;
background-size: auto;
background-origin: content-box;
}
