My background image won't align between the divs in this code - I have tried clearing them to no avail. Anyone know what's causing it, or how I can get it to work? CSS in html for convenience.

```
<div class="header" style="height:200px; background-image: url(bg.png); margin:-8px;">
<img src="logo.png" style="margin-left:auto; margin-right:auto;" />
</div>

<div style="text-align:center;">
    <div style="background-image: url(bg.png);background-position:center;  
display:inline-block; width:90px; border-bottom-left-radius: 20px;">Div 1</div>
    <div style="background-image: url(bg.png);background-position:center;  
display:inline-block; width:400px;margin:-4px;">Div 2</div>
    <div style="background-image: url(bg.png);background-position:center;  
display:inline-block; width:90px;border-bottom-right-radius: 20px;">Div 3</div>
</div> 

```
