Analog Clock in Pure CSS3: Accurate Time Without JavaScript

Today – another great article – we are going to create pure CSS3 Analog Clock without any javascript (we are going to use power of CSS3 with animations to build it). Our clocks have three arrows on the face – hour, minute and second. Each of them is a narrow rectangle rotated to the desired angle. How does it work? – Easy: I am using necessary delays for all these arrows. How exactly – read on.

For our clock, I have prepared -webkit and -moz styles. So please keep in mind that this clock will work only in Firefox, and Webkit-based browsers (Chrome and Safari). If you like – you always can expand the necessary styles (for the arrows/hands) for IE and Opera browsers (by adding the same stylesheets with -ms and -o prefixes).

Here are the example and downloadable package:

Ok, download the example files and lets start coding !

Step 1. HTML markup

The mark-up for our clock is not very simple – it contains a lot of DIV elements. Each of them is one of our arrows/hands. Here it is.

index.html

            </div>
        </div>
    </body>
</html>

Step 2. CSS

Now – CSS styles. As usual, we won’t publish main page layout styles (layout.css). But, here are the stylesheets for our clock:

css/clocks.css
#clock {
    background: #fff url(cface.png) 0 0 no-repeat;
    height: 500px;
    margin: 0 auto;
    overflow: hidden;
    position: relative;
    width: 500px;

    -webkit-border-radius: 250px;
    -moz-border-radius: 250px;
    -ms-border-radius: 250px;
    -o-border-radius: 250px;
    border-radius: 250px;
}

/* seconds */

-moz-animation-delay: 3540s;
-webkit-transform: rotate(264deg) translatex(110px);
-webkit-animation-delay: 3540s;
}

/* hours */
@-webkit-keyframes hours_effect {

-moz-animation-delay: 3600s;
-webkit-transform: rotate(-150deg) translatex(110px);
-webkit-animation-delay: 3600s;
}
#clock #h3 {
-moz-transform: rotate(-120deg) translatex(110px);
-moz-animation-delay: 7200s;
-webkit-transform: rotate(-120deg) translatex(110px);

#clock #h12 {

-moz-animation-delay: 39600s;
-webkit-transform: rotate(150deg) translatex(110px);
-webkit-animation-delay: 39600s;
}

Now – you can understand the main idea. I won’t publish all ‘recurring’ styles for each arrow. Full code you can find in our package.

Step 4. Images

For our clock I have used a single image (as the face of our clock):

Conclusion

Finally we have built our clock! This was difficult, but we did it. I hope that this be will interesting addition to your website. Don’t forget to tell thanks and leave a comment. Good luck!

Cool CSS demonstration, but not functional without a way to start with the current time, which is still going to require javascript or something server-side during page generation. Also, (and this is just conjecture) couldn't you drastically reduce the markup by using one div for each hand and animating the rotation?

Awesome one!Haven’t went through code yet,but it’s looks great!Nice work!
