You need to add a media query that reduces the font-size of the ‘cyclone analytics’ on smaller devices. The reason the nav bar is getting bigger is because the hamburger is being wrapped onto a new line.
So if you add a media query along the lines of:
@media only screen and (max width: 700px) {
.navbar-brand: font-size: 1rem;
}
It’ll work because the main logo is smaller, so the hamburger isn’t being wrapped. Hope that helps. 🙂
I have a web app that I’m working with where the Nav bar’s height doubles in size on a mobile view. Here’s what it typically looks like:

And here’s what it looks like an a mobile view:

What can I do to prevent this resizing? Is there a way to make the header and logo responsive based on screen size? Here’s the code I’ve got:
.navbar {
background-color: #951010;
padding-top: 1em;
padding-bottom: 1em;
}
.navbar-brand {
color: #FFF;
font-size: 2em;
}
.navbar-default .navbar-nav>li>a {
color: #FFF;
}

What am I missing here?
I can not replicate this “problem” even with your codepen, on 300px width… Seems all is ok…
@ikiK – I have this deployed as a Heroku app and viewing the site on mobile presents the issue.
Cant help with that, like i say I can not replicate the problem.
Thanks for this, it sent me in the right direction. Apart from a bit of formatting, this is what I was looking for.
