img-responsive failure by using IE11

Question

I am new to this and I'm building my first landinpage with the help of bootstrap. So don't be mean to me ;)

I added a big picture with the width of 2400px and added the class "img-responsive" to make the suitable for every viewport. But in IE11 it does not work. In Mozilla or Chrome there is no problem but I can not find any solution. Can somebody give me some advice?

Thank you very much, Tobi

Here is a example of the html:

<img src="images/headerbild.png" alt="Flensboxx" class="img-responsive"/>

Answer 1

just insert this in cover.css

.img-responsive{width: 100%;}
