Alright, this is pretty much what I think you're after. Using some images for example, obviously you'd change as needed. Let me know if I need to explain things a little better.
First of all, we're starting with the banner which we want to use: Banner (http://vulture.killanet.net/1.gif)
We're going to split this up into 2 images which we'll use in the header:
1 - http://vulture.killanet.net/2a.gif
2 - http://vulture.killanet.net/2b.gif
I think you can appreciate where they come from. Now its time for some code :D Lets look at the HTML first before we do the CSS.
<div id="top">
<p class="left">
<!--This is the logo image (#1 above)-->
<img src="2a.gif" alt="header" />
</p>
<p>
<!--phpAdsNew Invocation code goes here (Remote JS)-->
</p>
</div>
Nothing too complicated here. We've created a division with id "top", inside that we've put 2 paragraphs (they simplify things...could have used another div). The first paragraph we've assigned the class "left". Inside this paragraph is the the logo of our site, inside the second is our remote javascript code from phpAdsNew.
Now to make it looks the way we want...we need CSS. This should either go inside the <style> tag or in a remote CSS file - depending on what you use.
#top {
background: url('2b.gif') repeat-x;
border: 0;
margin: 0;
height: 65px;
}
#top p {
background: transparent;
margin: 0;
padding: 8px;
text-align: right;
}
#top p.left {
margin: 0;
border: 0;
float: left; Looks ugly, don't worry. First we take the div with id "top" and give it a background (image #2 above). We also give it a height which you can change if needed. Border and margin are set a 0 so that we don't get some unwanted space.
The second bit of code is defining what should happen to all paragraphs in div "top". We tell it to make sure the background is transparent (so we can see the gradient) then add some padding to keep it away from the edges. More importantly we tell everything to go to the right hand side.
The last code bit is dealing with all paragraphs in div "top" which have class "left". As above we're making sure border and margin stay out of the way. The final line tells everything in this div to float over to the left.
Hopefully you'll be able to see how it has all build up. You should be able to get something like this (http://vulture.killanet.net/top.html) if its working correctly. The part of the right is coming from phpads (refresh and it'll change). I know its not the same size as what you intend on using, but shouldn't make much of a difference.
Let me know if you run into problems, and good luck :greenthum
