Creating HAL 9000 with Pure CSS

You may be wondering why on earth am I writing a tutorial about creating HAL 9000 with pure CSS. First of all, this tutorial shows you how advanced CSS has become and how you can use these techniques to your own advantage. HAL 9000 is a fictional character in Arthur C. Clarke's Space Odyssey series.

Secondly, HAL 9000 can be a great notification button for web application. I can definitely see myself having a similar notification button on my app one day. With this tutorial you will learn the techniques used to create HAL 9000 from scratch with pure CSS. Without further ado, let's head on and bring HAL 9000 to life.

HAL9000


Manufacturing HAL 9000

Let’s start with the HAL 9000 body. I used a simple background gradient style to create a smooth body for HAL 9000. The tricky parts are the frame and the lens. I used a separate div for the frame instead of a border so that I can add a background gradient style to the frame to create depth. For lighting and shadows of the frame, I used a combination of layered box-shadow to create a believable surface for the frame.

Hal Life

For the lens, instead of creating it in one go with background gradients, I decided to create a separate div so that I can animate each one individually. I also ran into trouble when trying to animate HAL 9000 with one background gradient. Unfortunately, complex gradients and CSS transitions don’t play well together (yet) so to solve this I have to separate colors into multiple divs.

You can see an example code below:

CSS

notification {
    background: #2D2A2B;
    background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#494852), to(#2A2A30));

Bringing HAL 9000 to Life

Now we’ve manufactured HAL 9000, let’s bring it to life by adding some animations to it. Let’s begin by making the yellow and red parts of the lens glow. As you can see in the code below, I have defined 2 animation keyframes, blink-red and blink-yellow. These keyframes will determine how the animation will behave. I have each keyframe increase and decrease the size of the yellow and red parts of the lens to give HAL 9000 a glowing effect. I’ve also made the animation to run infinitely.

Hal Eye

Since you might want to turn this into a notification button, I’ve made these animations to be triggered only if the main "notification" div has a class called "active" in it.

You can see the example code below:

CSS

.notification {
    background: #2D2A2B;
    background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#494852), to(#2A2A30));

HAL 9000 Interaction

Now that our HAL 9000 is alive, let’s create some interactive animation. Let’s add a cool reflective animation when someone hovers over HAL 9000. In order to create a hover effect that resembles the reflection of lights on a shiny surface, I’ve added a new div called “hover-effect” to perform this effect.

You can see in the demo or from the code below that I exploited the transition of a border-width style by shrinking the border-width from 15 pixels to 0 to create a reflective-like animation.
