“Real” analog clocks - particularly older ones - are typically base 60 “digital” under the hood, even mechanical ones.
NICE CLOCK HTML UPDATE
That’s because rather than having it jump 30 degrees at a pop, it would be nice to have it update at the same 6 degrees as the other hands. You might wonder why the hours calculation gets the minutes. #clock clockUpdate() setInterval(clockUpdate, 1000) Stylesheetįirst let’s style the outer container with a nice box-shadow generated border. Using generated content we can plug in our various bits and pieces, but we still need a slew of extra containers in the markup to hook our before:after to. Basic MarkupĮven if we’re going to generate the internal markup in the scripting in the final version, it helps to have a basic example of the markup elements coded first so we can make sure all our ducks are in a row. HTML and CSS on their own can work wonders, but one also has to be careful that you don’t put elements in the markup that are “scripting only” as they can confuse users on screen readers, braille readers, and the like. If we do everything in EM, we can resize elements like this using nothing more than font-size on the outermost container! That means it doesn’t scale to user preferences like EM would, and it makes it harder to resize. The biggest flaw though is people are always working in the least accessible metric - pixels. The most any scripting would/should need to do (unless using Canvas) is plug in the elements inside the clock face, and then manipulate them for rotation. As if is some arcane tome too hard understand. One of the things I constantly see is how many implementations tend to use a lot of JavaScript with no scripting-off graceful degradation plan. Whilst I answered their question as cleanly as I could in a drive-by answer, I thought a more polished and robust copy would make a good article.
Over on DigitalPoint it was asked if it were possible to make a clock face using just HTML and CSS.
