Moving on from our .psd tutorial, this collection of screencasts will walk you through building our admin bar for the browser. We have a few obstacles to take into account, and we'll be exploring some interesting ways of getting round them. Let's get going!
A Couple of Considerations
There are a couple of things we need to bear in mind before we jump into building this. Firstly, our admin bar is going to rob its parent website of some pixels at the top of the page. If the web site beneath happens to have valuable content at the very top, it's going to be masked by the admin bar. For this reason, we'll need to push the whole web page downwards to begin with.
Secondly, we need to bear in mind that our CSS is going to be a valid part of the overal web page. If we're not careful, it will influence styling beyond the boundaries of our admin bar - not good.
Lastly (and related to the previous point), our admin bar is open to influence from CSS belonging to the parent web page. We'll need to make sure our markup and presentation is completely autonomous.

Part 1: Basic Markup
Let's kick things off by organizing the project structure, and laying out some basic markup. We'll also make some significant changes to our reset.css, and take a quick look at what's involved with using Gravatar images.
Part 2: Initial Styling
Having set out our markup, let's now establish some styling to make the whole thing look more recognizably 'admin bar'. We'll cover some @font-face usage, including the brilliant Web Symbols font for our icons. During the process we'll also make interesting use of the
:last-child, and the seldom seen
:only-child pseudo selectors.
- Google Fonts API Droid serif
- The Web Symbols font, from Just Be Nice Studio
- The Whitey subtle background pattern
Part 3: Yellow Bits
In this video we'll tackle the yellow priority button, and the little notification sign. We'll look at CSS3 gradients, transitions, and to help us with the various browser vendor prefixes we'll examine some useful online tools.
Part 4: Search Form Markup and Styling
It's time to get the search form looking more respectable. We'll approach it as semantically as possible using the HTML5
input type="search", and then we'll look at fixing the presentational problems doing so entails.

- w3.org reference on input type="search"
- w3.org reference on the HTML5 placeholder attribute

Part 5: CSS3 Dropdown Menu
We're now going to use a classic approach to building our dropdown menu in HTML and CSS. We'll briefly discuss accessibility, and explore some transitional effects to make the whole thing look as smooth as possible.

We're nearly done, but there are a couple of details which need sorting out. There's the tooltip (watch out for that Quick Tip where we look at the HTML5/CSS3 options available to us). We haven't properly considered cross-browser compatibility yet, and neither have we actually tested our bar within a genuine HTML web page. Plenty still to do then, stay tuned!
