Trying to imitate jQuery website

[vik_2010]

I was looking at the jQuery website, and trying to replicate it using only their icons, but not looking at their source code.

I had two big questions that I wasn't able to find out.

1] The navigation bar at the top:
At the top of the website they have a navigation bar in which the links, when highlighted, display a light blue bar a couple pixels below.

I know there is a

a:hover {text-decoration:none;}

but I don't think that's it. The bar is displayed a lot lower than that css tag permits, and it comes in a bright-blue color completely different from the color of the text. How would you replicate that? Perhaps there are a number of different ways, but any would be acceptable. I don't think its Javascript, because the lines still come even with No-Script active.
Also, how to you get that dark line at the bottom of the bar separating it from the rest of the header? All i was able to manage was {background-color:#[some hex number];} inside a table i created specifically for the nav-bar, but my website still lacked that emphatic divider between the bar and the rest of the header.

2] Half way down the site they have a box in which they show "who else is using jQuery." They show a bunch of different icons for companies/sites like BOA, MLB, Drupal, etc. Looking at the source, I saw that all they did was create a series of tags like so:

<a href = "****">[Company name here]</a>

but didn't have any <img> tags at all. How do did they get the logo images when their source just makes it seem as though they're listing a bunch of hyperlinks?

Thanks,

Consider using Firebug to assist you here.

You can easily inspect DOM elements, style, javascript etc. See attached screenshot.

Good Luck

The “Who's using jQuery” links are using a technique called CSS sprites:

The blue bar is probably a border, and you can achieve a soft glow with the CSS3 drop-shadow property (although that only works in some browsers).
