<h1>Navbar example</h1>
<p>This example is a quick exercise to illustrate how the default, static and fixed to top navbar work. It includes the responsive CSS and HTML, so it also adapts to your viewport and device.</p>
<p>To see the difference between static and fixed top navbars, just scroll.</p>

But I have some problems, which are these and I am not able to solve them. I need
Reduce the distance between the "free" and the Home
Dropdown does not work: /
When I put an icon in front of the one section of the navbar, the format is changed. How can I avoid it?
I tried to put a padding to the right of the image but I did not get anything to reduce the distance. To avoid the change of style, I tried to put a button and the dropdown no idea.
Let's see if you can help me. Greetings
