Can't remove white space between header and navbar when using Materializecss - html

Question

I am using the materializecss framework from materializecss.com. I have a simple image that I place above the navbar from materializecss and there is a small white space. I checked the source and there is no margin, padding or border at all. The space goes away if I put the navbar above the image so I am not sure what the problem is.
<img id="header" src="/public/images/header.gif" alt="Header"/>
<nav class="grey darken-4">
<div id="navbar" class="nav-wrapper">
<ul id="nav-mobile" class="hide-on-med-and-down">
<li>Profile</li>
<li>Skills</li>
<li>Projects</li>
</ul>
</div>
</nav>
I am not using any other css besides the materializecss css file. Any ideas? I don't think that css has any margins anywhere as I don't see it when viewing the source for any of the elements.
Edit: Here is a jsfiddle: http://jsfiddle.net/0tL9up9s/ The list elements aren't appearing because I haven't copied over the javascript but you can still see the white space between the image and the navbar.

Answer 1

OK, I think it has to do with the fact that the image is display:inline and therefore has dimensions that include the line-height.
Setting your image to display: block will correct this issue.
CSS
#header { display:block; }
Or (HTML)
<img id="header" src="/public/images/header.gif" style="display:block" alt="Header"/>

Answer 2

Adding a html {line-height: 0} to the end of the materialize.css file seems to fix the problem. I have no idea if it will break any other functionality though, so be careful.
