Make background image responsive
提问by insanity
I want to make background image responsive both in width as well as in height so that i can run it in mobile.
我想让背景图像在宽度和高度上都具有响应性，以便我可以在移动设备上运行它。
I have used this
我用过这个
.your_background_class_name {
width: 100%;
height:auto;
top: 0px;
left: 0px;
z-index: -1;
position: absolute;
}
but it works in width only not in height. What changes should i do to make it work?
但它只适用于宽度而不适用于高度。我应该做哪些更改才能使其正常工作？

This worked for me:
这对我有用：
#header {
background-image: url('http://www.fillmurray.com/g/1920/1080');
background-repeat:no-repeat;
background-size: 100%;
background-position:top left;
position: relative;
}
#header .container {
height: 893px;
position: relative;
}
#header .div1 {
position: absolute;
top: 20px;
}
#header .div2 {
position: absolute;
bottom: 20px;
right: 20px;
}<div id="header">
<div class="container">
<div class="div1">
Top left content
</div>
<div class="div2">
Bottom right content
</div>
</div>
