Answer 1

• iOS Safari has buggy behavior with background-size: cover; + background-attachment: fixed ;
• Safari (OS X and iOS) and Chrome do not support background-size: 100% px; in combination with SVG images, it leaves them at the original size while other browsers stretch the vector image correctly while leaving the height at the specified number of pixels.
• iOS Safari has buggy behavior with background-size: cover; on a page's body.
• macOS Safari 10 is having frame rate issue with background-size .
• Android 4.3 browser and below are reported to not support percentages in background-size

Answer 2

A possible solution to this issue is still a pure CSS Fallback

CSS Tricks has three great methods, the latter two are fall backs for when CSS3's cover doesn't work.

HTML

<img src="img/main_pic2.png" id="bg" alt="">

CSS

#bg {
  position: fixed; 
  top: 0; 
  left: 0; 

  /* Preserve aspect ratio */
  min-width: 100%;
  min-height: 100%;
}
