Google custom search pushed outside box bootstrap IE - css

Question

For education I tried to make my site in a sort of flat design, I use bootstrap as framework. I installed an google custom search as the site search.
In firefox no problems at all, but when I open my site in IE (the usual course of messup), it gets pushed outside the header in a full width
The searchbar gets to 80% width on 1000px or lower, but in ie its 100% all the time. (I'm using IE 11)
I couldn't find any code that should be off
.cse .gsc-control-cse, .gsc-control-cse {
background-color: transparent !important;
border: none !important;
}
.gsc-control-cse {
border:none !important;
background-color: transparent !important;
}
input.gsc-search-button, input.gsc-search-button:hover, input.gsc-search-button:focus {
border-color: none !important;
background-color: #3cb878 !important;
background-image: none;
filter: none;
}
input.gsc-input, .gsc-input-box, .gsc-input-box-hover, .gsc-input-box-focus {
border-radius: 5px;
}
input#gsc-i-id1.gsc-input0 {
background-image: none !important;
background-color: #fff;
}
input.gsc-search-button, input.gsc-search-button:hover, input.gsc-search-button:focus {
border-color: #369;
background-color: #3CB878;
background-image: none;
min-height:25px;
filter: none;
}
.gsc-search-box {
height: 100%;
margin-top: 20px;
display: inline-block;
}
/*google*/
.social .pull-left{
overflow: hidden;
}
#gsc-i-id1.gsc-input{
background-color: #fff;
background-image: none !important;
}
.gsc-control-cse, .gsc-control-cse{
height: 30px;
margin:0px !important;
padding: 0px !important;
border: 0px !important;
background-color: transparent !important;
}
.gsc-control-cse {
border: 0px !important;
background-color: transparent !important;
}
input.gsc-search-button{
height: 25px !important;
}
.gsc-input-box{
border-radius: 5px ;
background-image: none !important;
}
.gsc-search-button .gsc-search-button-v2 {
background-image: url(../img/search_box_icon.png);
background-repeat: no-repeat;
background-position: center center;
border: 0px !important;
}
.gsc-search-button .gsc-search-button-v2:hover {
background-color: #00a651 !important;
background-image: url(../img/search_box_icon.png);
}
.gsc-search-box .gsc-input {
line-height: 0px !important;
}
#media (max-width: 1000px) {
#___gcse_0{
width: 80%;
margin: 0 auto;
}
Is it possible IE is struggling with the media queries ?

Answer 1

I got working by adding changes to the stylesheet:
.navbar-right {
width: 200px; /* Change it if needed */
}
#media (max-width: 1000px) {
.navbar-right{
width: auto;
}
}
Also the only CSS written for .navbar-right I saw was margin-right: -15px;. Don't know if this was intended or some of your code is missing. :)
