Answer 2

You can use this. I have tested and its working 100% correct:

background-image:url('../images/bg.png'); 
background-repeat:no-repeat;
background-size:100%;
background-position:center;

You can test your website with responsiveness at this Screen Size Simulator: http://www.infobyip.com/testwebsiteresolution.php

Clear Your cache each time you make changes and i would prefer to use Firefox to test it.

If you want to use an Image form other site/URL and not like: background-image:url('../images/bg.png'); //This structure is to use the image from your own hosted server. Then use like this: background-image: url(http://173.254.28.15/~brettedm/wp-content/uploads/Brett-Edmonds-Photography-14.jpg) ;

Enjoy :)

Here is sass mixin for responsive background image that I use. It works for any block element. Of course the same can work in plain CSS you will just have to calculate padding manually.

@mixin responsive-bg-image($image-width, $image-height) {
  background-size: 100%;
  height: 0;
  padding-bottom: percentage($image-height / $image-width);
  display: block;
}


.my-element {
  background: url("images/my-image.png") no-repeat;

  // substitute for your image dimensions
  @include responsive-bg-image(204, 81);
}

    <style> 
         * {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

#res_img {
  background: url("https://s15.postimg.org/ve2qzi01n/image_slider_1.jpg");
  width: 100%;
  height: 500px;
  background-repeat: no-repeat;
  background-size: 100% 100%;
  background-position: center;
  border: 1px solid red;
}

@media screen and (min-width:300px) and (max-width:500px) {
  #res_img {
    width: 100%;
    height: 200px;
  }
}

    </style>

<div id="res_img">
</div>

Answer 5

Try using background-size but using TWO ARGUMENTS One for the width and the other one for the height

background-image:url('../images/bg.png'); 
background-repeat:no-repeat;
background-size: 100% 100%; // Here the first argument will be the width 
// and the second will be the height.
background-position:center;

Answer 6

#container {
    background-image: url("../images/layout/bg.png");
    background-repeat: no-repeat;
    background-size: 100% 100%;
    height: 100vh;
    margin: 3px auto 0;
    position: relative;
}
