html {
    
    /* block comments */
    
    head {
        title = $title // insert $title into the title tag (HTML-escaped)
    }
    
    body {
        #left { // <div id="left">
            ul.nav-main { // <ul class="nav-main">
                // foreach, if, while, etc. are keywords:
                
                foreach $menu as $url => $title {
                    // double construction - a-tag inside an li-tag:
                    li a {
                        href: $url // href-attribute on the parent a-tag
                        = $title // insert $title into the a-tag (HTML-escaped)
                    }
                }
            }
        }
        
        #main {
            h1.headline = $title // <h1 class="headline">
            
            section {
                // literal output: (not HTML-escaped)
                
                == "What if <strong>HTML</strong> looked more like CSS?"
            }
        }
        
        #footer {
            p = "Copyright (C) " . date('Y')
        }
    }
