#header

z-index: -1;
}
currently when setting in img{} position to relative and z-index to 1 http://i.stack.imgur.com/XkIjk.png want to http://i.stack.imgur.com/d6HU8.png
See the comments, the answer turned out to be:
<h1 id="site-name">
in a span
. Use:
#site-name { position: relative } #site-name span { position: absolute; top: 0; left: 0; width: 100% }
For z-index
to do anything, you need to also add position: relative
.
However, setting a negative z-index
value sometimes does strange things .
What are you actually trying to do?
add
position: relative;
to your img {}
z-index
only applies to elements that are absolute
, fixed
or relative
.
The default is static
, so you'll need to add position: relative
to your img
.
