Bootstrap Navbar with dynamic search box - css

Question

I'm trying to figure out how to make the above code behave well on displays > 768px and < 768px. Right now is working fine for resolutions below 768px, but I can't make it work for resolutions above that.
That's the what I'm trying to do:
Resolution above 768px - Full page (search box with 100% remaining width):
Resolution below 768px (only search box visible):
Code:
.navbar .navbar-form {
padding: 0;
margin-right: 0;
margin-left: 0;
border: 0;
-webkit-box-shadow: none;
box-shadow: none;
}
.clear {
width: 1%;
display: table-column;
}
#media(max-width:767px) {
.navbar .navbar-form {
padding-left: 15px;
padding-right: 0;
}
.navbar .navbar-form .input-group {
padding-right: 15px;
}
.navbar .navbar-form .form-control {
border-top-right-radius: 4px;
border-bottom-right-radius: 4px;
}
}

Whew, you have yourself a nasty little problem here. It took me a while, but I think I've gotten you a solution together.
First, you need to do the following:
Add display: inline to your form-group
Add display: table to your input-group
Add width: 1% to your input-group-btn
These changes are from this issue here (what you want, but keeps the search bar inside the collapse menu) - Bootstrap 3 - How to maximize input width inside navbar
The next changes you need to make are for when you are above the 768px breakpoint, otherwise it will mess up your collapse menu.
#media(min-width:768px) {
.container-fluid {
display: flex;
}
.navbar-header {
flex: 1;
}
}
Lastly, you need to remove navbar-right from your navbar-form.
Here is a JSFiddle - An embedded snippet is also included.
.navbar .navbar-form {
padding: 0;
margin-right: 0;
margin-left: 0;
border: 0;
-webkit-box-shadow: none;
box-shadow: none;
}
.clear {
width: 1%;
display: table-column;
}
#media(max-width:767px) {
.navbar .navbar-form {
padding-left: 15px;
padding-right: 0;
}
.navbar .navbar-form .input-group {
padding-right: 15px;
}
.navbar .navbar-form .form-control {
border-top-right-radius: 4px;
border-bottom-right-radius: 4px;
}
}
#media(min-width:768px) {
.container-fluid {
display: flex;
}
.navbar-header {
flex: 1;
}
}
