Use html5 to create a clock animation effect

Let’s take a look at the renderings first (regardless of color matching):

(Learning video sharing:html5 video tutorial)

We must first understand how to implement this clock. Don’t think about animation for the time being, learn to dismantle the problem and implement it step by step.

First we need to draw a square with a border, give a rounded corner to achieve the outermost ring, and then rotate a long rectangle multiple times to achieve the scale

Just draw another white circle to cover it to achieve the standard scale

Finally add three rectangles and the small circle in the middle The initial state of the clock can be realized

Code implementation

After understanding the above process, the code implementation is much simpler. The only thing that needs to be considered is the optimization of the code. In order to make it simple and clear, below How to implement the first step, there is a lot of repeated code.

Regarding animation, we only need to set the rotation animation, and the animation of the hour, minute and second hands only need to change different times.

Please see the code for specific details:
