Here is the neat little block of CSS that I use to resize a background image to fit the size of the browser window the site is being viewed in:
body {
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}Let me know if you have any questions or need help with this! 
Here is the code that I use to set all the links within a certain div of a web page to open in a new window:
<script type="text/javascript">
var linktarget="_blank" //Specify link target added to links when set to open in new window
var formcache=document.targetmain
function applywindow(){
if (typeof targetlinks=="undefined") return
if (!formcache || (formcache && formcache.targetnew.checked)){
for (i=0; i<=(targetlinks.length-1); i++)
targetlinks[i].target=linktarget
}
else
for (i=0; i<=(targetlinks.length-1); i++)
targetlinks[i].target=""
}
function collectElementbyClass(){
if (!document.all && !document.getElementById) return
var linksarray=new Array()
var inc=0
var alltags=document.all? document.all : document.getElementsByTagName("*")
for (i=0; i<alltags.length; i++){
if (alltags[i].className=="your-link-class")
linksarray[inc++]=alltags[i]
if (alltags[i].className=="your-div-class"){
var alldivlinks=document.all? alltags[i].all.tags("A") : alltags[i].getElementsByTagName("A")
for (t=0; t<alldivlinks.length; t++)
linksarray[inc++]=alldivlinks[t]
}
}
return linksarray
}
if (formcache && formcache.targetnew.checked) //overcome IE bug, manually check checkbox that has "checked" attribute
setTimeout("document.targetmain.targetnew.checked=true",100)
var targetlinks=collectElementbyClass()
applywindow()
</script>
Copy and paste that code into your web page just before the closing < body > tag.
Next, change your-link-class and your-div-class in the code to the class of the links or divs whose links you want to open in a new window.
Finally, simply add the class your-link-class (or whatever you changed it to) to any links that you want to open in a new window OR add the class your-div-class (or whatever you changed it to) to the div whose links you want to open in a new window.
For example: if you change your-link-class to blank, you would add this class to each link you want to open in a blank window:
<a href="http://yourwebsite.com" class="blank">Your Link</a>
And if you change your-div-class to blank-div, you would add the class to the entire div whose links you want to open in new windows:
<div id="mydiv" class="blank-div"> <a href="http://firstwebsite.com">Link #1</a> <a href="http://secondwebsite.com">Link #2</a> <a href="http://thirdwebsite.com">Link #3</a> </div>
Each link in this div will automatically open in a new window.
