CSS inline-block: how does it work?

Hello, so I have the following code setup:

<!DOCTYPE html>
    <style type="text/css">
    body { background-color: #2574b0; }
    .menullo {
	padding:10px 15px 5px 15px;
	margin:0 5px 10px 0;
        <div style="width:100%; position:relative;top:10px;height:600px; text-align:center;">

              <div class="menullo">
              Line1<br />
              Line2<br />
              <div class="menullo">
              Line1<br />
              Line2<br />

Open in new window

There's always something or other about css that's bugging me to no end. In this instance, can someone explain to me why, if I remove the &nbsp; from the first "menullo" div, that same div gets out of line? It lowers itself about 25 px, see pictures:

Can some good samaritan explain this to me?
Thanks a lot guys.

Thanks a lot. But still, why does this happen? Does the content of the divs influence their alignment?
By default the vertical-align is baseline for inline elements, so you need to override it.
