@media only screen and (min-width: 900px) {
.map_left {
display: inline;
float:left;
width: 100px;
height: 100px;
border: 3px solid green;
}
.map_right {
display: inline;
float:right;
width: 100px;
height: 100px;
border: 3px solid blue;
}
}

为什么第一个div(包含另外两个div)不会自行调整大小?我不想用像素设置宽度和高度,我想让它自己调整大小,是否可能?

因为您设置了witdth="1000px"
,所以放置xxx%
或者没有(默认为100%)
