Why the background image does not fill the entire div
I have the following code which displays a SPAN inside a DIV and then another DIV under it which displays some texts. The issue I am having is when I resize the browser the texts and the background image gets all out of place.
Here is a screenshot of how the image is not filling up the DIV :
Also, when I resize, the text are all out of place:
Here is the HTML:
<div id="subpageHeaderImageSection">
<div id="subpageHeaderLeft">
<!--<img src="theImages/wcu.png" style="z-index: 5; position: absolute; bottom: 0; left: 10%; width: 194px; width: 185px;" />
<span id="quoteText" style="z-index: 4;">

Here is the CSS:
#subpageHeaderImageSection {
position: relative;
top: 0;
width: 100%;
height: 450px;
}
#subpageHeaderLeft {
position: absolute;
left: 0;
float: left;
width: 100%;
height: 100%;
background: url('../theImages/subpageHeaderImage.png') no-repeat;
background-size: 100%;
}
#subpageFooter {
position: relative;
width: 100%;
height: 555px;
background: url('../theImages/bg_80_w.png');
box-shadow: 0 0 10px #FFFFFF;
}
#subpageFooterRight {
position: absolute;
right: 0;
width: 40%;
height: 100%;
float: right;
background-color: #000000;
}
#subpageFooterLeft {
position: absolute;
left: 0;
float: left;
width: 60%;
height: 100%;
}
#quoteText {
position: absolute;
bottom: 30%;
left: 40%;
overflow: hidden;
font-family: 'daysregular';
font-size: 30pt;
}
Two things I would really like help with:
使用background-size: 100% 100%完全填充（也许拉伸）其他明智的使用background-size: cover作为@Andras说
使用background-size:cover ，它会填充。
