Menu
I'm starting to use the polymer 0.5 code to build a responsive website. I know it's not fully finished, but nevertheless I find it pretty neat and simple to get stuff done quickly.
Now, I'm using the core-scaffold as general layout. I know how to color the sidebar, but I'm not sure where I can style the main content settings.
<html>
<head>
<style>
html,body {
height: 100%;
margin: 0;
background-color: #E5E5E5;
font-family: 'RobotoDraft', sans-serif;
}
core-toolbar {
background: #E5E5E5;
color: white;
}
paper-item.core-selected {
color: #99182c;
fill: #99182c;
}
</style>
</head>
<body unresolved touch-action="auto">
<core-scaffold>
<core-header-panel navigation flex mode="seamed">
<core-toolbar style="background-color: #99182c; color:#fff;">Main site name</core-toolbar>
<core-menu selected="0">
<paper-item icon="home" label="Home"></paper-item>
<paper-item icon="today" label="Activities"></paper-item>
<paper-item icon="account-box" label="People"></paper-item>
<paper-item icon="theaters" label="Pictures"></paper-item>
<paper-item icon="info" label="Info"></paper-item>
<paper-item icon="lock" label="Login"></paper-item>
</core-menu>
</core-header-panel>
<div tool>Home</div>
</core-scaffold>
</body>
</html>
So the core-toolbar is styling the left sidebar, but how do I style the main page?
Another issue I'm having is that I'd like to work with the paper-elements. However, when using this core-scaffold, you'll notice that when the screen is small enough and the tab appears to open the left menu bar, it's a 'normal' button and not a paper one. Since this is in the core-scaffold, I don't directly know how to change this (if this is possible). Any ideas?

I ran into the same problem and it turns out that you can style the elements (the toolbar) inside other elements (core-scaffold) using CSS with a special syntax to access the inner component (which is inside the Shadow DOM) using the ::shadow pseudo-element.
The top rule changes the color of the title background while the second one changes the background of the content area.
core-scaffold::shadow core-toolbar {
background: #E5E5E5;
color: black;
}
core-scaffold::shadow core-header-panel {
background: #FFF;
color: black;
}

Update: This didn't work properly with Firefox because of shims. What did it was adding styles with the shim-shadowdom directive that gets interpreted only when on a non webcomponent/shadowdom native platform:
<style shim-shadowdom>
core-scaffold core-toolbar {
background: #EEE;
color: black;
}
core-scaffold #main core-header-panel {
background: #FFF;
color: black;
}
</style>
Note that to change the background of the content area I also had to select #main so porting ::shadow rules might need a bit of inspecting...
Finally when you need to properly deal with Firefox and other browsers from within a webcomponent/polymer element you can use the polyfill-rule or polyfill-unscoped-rule.
