Doesn’t matter as long as they are not the default ?post=2
The structure affects posts but page permalinks are always in the format url/slug
I always use the year/month/title option.
That CSS would only change an image that has the id “img” and a class “source-image”, i.e.
<img id="img" class="source-image" src="...etc..." />
It seems like you’re trying to make an image the full size of the page which isn’t a sensible solution.
The style you need to use is
background: url(theimage.jpg) left top no-repeat;
and you should probably be applying it to the body
so
body
{
background: url(theimage.jpg) left top no-repeat;
}
and if you want the background to not scroll with the document
body
{
background: url(theimage.jpg) left top no-repeat fixed;
}
theimage.jpg must be relative to the style sheet or absolute.
Assuming you have permalinks set up, create a page with the permalink forums
so the full url would be http://localhost/wordpress/forums
Because the directory exists, when someone goes to the page they will end up on your forum.
