我有一个中心框,但当它的宽度或高度发生变化时,它的页眉,页脚,左侧边栏和右侧边栏都会相应地改变。
即使宽度或高度发生变化,中心框也应始终位于页面的中间位置。
这是我的代码:
<html lang="en">
<head>
<script src="jquery-1.10.1.min.js"></script>
<script>
var modified_width, modified_height;
function set_width_height(width,height){
var width_factor=width/1024;
var height_factor=height/768;
var scale_factor=(width_factor>height_factor)?width_factor: height_factor;
modified_width=width*scale_factor;
modified_height=height*scale_factor;
return {width:modified_width, height:modified_height};
}
$(document).ready(function(){
set_width_height(800,480)
/* var width2 = 1024 - modified_width;
var height2 = 768 - modified_height;*/
$("#id6").css({'width':modified_width, 'height':modified_height});
/*
$("#id6").css("width",modified_width);
$("#id6").css("height",modified_height);*/
// alert(modified_width)
width1 = (1024 - modified_width)/2;
height1 = (768 - modified_height)/2;
$("#id2").css("width",width1);
$("#id4").css("width",width1);
$("#id3").css("height",height1);
$("#id5").css("height",height1);
})
</script>
<style>
.inc {
position:absolute;
border:1px solid white;
}
#id1{
width:1024px;
height:768px;
}
#id2{
left:0;
top:0;
bottom:0;
width:20%;
height:100%;
background:red;
}
#id3{

}

#id5{

}
#id6{

}
</style>
