How laborious is it to make animation on HTML5 and related technologies similar to flash?

Question

Canvas

Hello!
Flash is dead?
And how much easier / harder is it to make a similar animation in HTML5 (click on the orange inscription in the center, there is obscene language)?
The fact that this is certainly possible on HTML5 is understandable, but if you rub your hands up to your elbows on the keyboard?
Can someone compare the labor costs and feasibility of HTML5 animation of such a plan?

Answer 1

Make a video, embed with video, start video on click. At the same time, what you do with this video does not matter, even in flash, the main thing is to render it as a video file.
The button "orange in the center" can be put there by absolute positioning or using js.
