How to responsive image in ionic from different screen size? - angularjs

Question

I am creating an ionic app, in that I need to add a four images in my home page in two row and each row has two images. The images size is 296*296.
I have tried the below code,
index.html
<ion-nav-view class="container" >
</ion-nav-view>
Home.html
<ion-view view-title="HOME">
<ion-content>
<div class="row" >
<div class="col-md-6 " id="img1">
<img src="img/hard.png" class="img-responsive " id="img1" >
</div>
<div class="col-md-6" id="img1">
<img src="img/soft.png" class="img-responsive " id="img1">
</div>
</div>
<div class="row" >
<div class="col-md-6 " id="img1">
<img src="img/welcome.png" class="img-responsive " id="img1" >
</div>
<div class="col-md-6" id="img1">
<img src="img/title.png" class="img-responsive " id="img1">
</div>
</div>
</ion-content>
</ion-view>
CSS
#img1{
width: 100%;
height: auto
}

Answer 1

Your ids for div and img are same i.e img1. Change the id and then try. And make width and height important may be some other css overwrites it. Tell me if this works or not.
#img2{
width: 100% !important;
height: auto !important;
}
<div class="col-md-6 " id="img1">
<img src="img/hard.png" class="img-responsive " id="img2" >
</div>
