HTML5 Sine Wave (animated)

This is an HTML5 wallpaper. HTML5Wallpaper © 2016[html5wallpaper.com]

It is fully customizable, ranging from background to canvas dimensions, line dimensions and colors.

The main file is the index.html. If you open this with Notepad you can see all the code (or open with browser and toggle the developer console). Even if you're not familiar with programming, customizing is really easy.
Every part that is customizable has comments above it. All you have to do is look at what is customizable, change the value, save the file and see how the background changed. The comments include the default value (how it is intended to look) and often also minimum/maximum values where it still looks nice.
Feel free to experiment, if you somehow break it because you changed something and don't know what, just look at the default values and put them back.

You can see the custom version (in pictures) here. Just click "Run" and you'll see the results. [www.w3schools.com] You can also use this page to edit and test your own customisations.

That's it! Enjoy!

** This is code from an existing webpage. I put it in WPE to see if it worked, and decided to share it. **
** I did analyze the code and wrote all the comments. Original code had no comments. **
