 <h1>Comply with CSP</h1>
 
 
 <p>
 If you're unfamiliar with Content Security Policy (CSP),
 <a href="http://www.html5rocks.com/en/tutorials/security/content-security-policy/">An Introduction to Content Security Policy</a>
 is a good starting point.
 It covers the broader web platform view of CSP;
 packaged apps CSP isn't as flexible.

 <p>
 It's very possible that you are using templating libraries
 and many of these won’t work with CSP.
 You may also want to access external resources in your app
 (external images, content from websites).

 <p>
 Use a library that offers precompiled templates
 and you’re all set.
 You can still use a library that doesn’t offer precompilation,
 but it will require some work on your part and there are restrictions.
 </p>
 
 <p>
 You will need to use sandboxing to isolate any content
 that you want to do ‘eval’ things to.
 Sandboxing lifts CSP on the content that you specify.
 If you want to use the very powerful Chrome APIs in your packaged app,
 your sandboxed content can't directly interact with these APIs
 (see <a href="app_external.html#sandboxing">Sandbox local content</a>).

-<h3>Access remote resources</h3>
+<h3 id="remote_resources">Access remote resources</h3>
 
 <p>
 You can fetch remote resources via <code>XMLHttpRequest</code>
 and serve them via <code>blob:</code>, <code>data:</code>,
 or <code>filesystem:</code> URLs
 (see <a href="app_external.html#external">Referencing external resources</a>).
 </p>
 
 <p>
 Video and audio can be loaded from remote services
 because they have good fallback behavior when offline or under spotty connectivity.

-<h3>Embed web content</h3>
+<h3 id="embed_content">Embed web content</h3>
 
 <p>
 Instead of using an iframe,
 you can call out to an external URL using an object tag
 (see <a href="app_external.html#objecttag">Embed external web pages</a>).
