Part of running an Elvis web site is getting in touch with Elvis fans the world over. One way to do this is to provide contact information on your site so that visitors can email you. Let's create an email link at the bottom of each page on your site that lets people send you feedback.

standard_template.ptPage Template to edit it.
<html metal:define-macro="page"> <body> <div metal:define-slot="body"> This is where the page's body text goes. </div> <hr> <a tal:attributes="href container/mail_link">mail webmaster</a> </body> </html>

Notice that there is now an email link at the bottom of every web page. The email link uses the property you defined and includes the title of the web page as the email subject.
The email link appears on every page because every page template
uses a Page Template Macro defined in the
template. Macros provide a way of sharing presentation elements
between pages. The
standard_template.pt template gives you a
convention for making pages share a common structure.
By consolidating content into components such as a common footer you can provide a uniform look and feel for your web site.
In the next lesson you'll see how to organize content with a collection of Zope objects.
