Question: Create a webpage that displays a clock where the second, minute, and hour hands tick. Write CSS to have the clock face, second, minute, hour
Create a webpage that displays a clock where the second, minute, and hour hands tick.
Write CSS to have the clock face, second, minute, hour hands all display correctly on top of each other. Make sure the red second hand displays on top of the minute and hour hand. (Try changing the order the div elements are written in the HTML)
Create intervals in the JavaScript file to make the clocks tick.
Use CSS transform rotation to rotate the hands of the clock.
.rotate { transform: rotate(45deg) } Change CSS values in JavaScript by getting reference to them through the DOM and setting a new value to their CSS properties:
let degrees = 45; const el = document.getElementById("myElement") el.style.transform = "rotate(" + degrees + "deg)" It would be useful to define functions that convert seconds, minutes and hours to how many degrees the hand should be rotated around the clock!
secondRotation(0) // returns 0 secondRotation(59) // returns (59 / 60) * 360 hourRotation(12) // returns 0 hourRotation(5) // returns (5 / 12) * 360
Bonus: Show Actual Time
Use JavaScripts Date objects to display the actual time.
const now = new Date()
Get now by declaring a new Date object. You can google for "MDN date methods" to see what helpful methods are attached to Date objects. There's helpful things like .getMonth(), .getSeconds() and who knows what else!
