LiveJournal provides the Navigation Strip for easy access to common site features. All system styles automatically support it, however, if you have a custom layer, you may need to include the built-in function for printing the Navigation Strip in your layer in order for it to display. This function will need to be added immediately after the <body> tag of the HTML structure.
In your custom layout or theme layer (depending on which you are using) locate the function Page::print(). Within it, you will find a tag, which may look similar to the following:
<body bgcolor="$*page_back" text="$*entry_text" link="$*page_link" vlink="$*page_vlink" alink="$*page_alink">
<div align="center">
Immediately after the body tag, you will want to close off the string, add $this->print_control_strip();, and then start the string again if necessary. This will make the code look something like this:
<body bgcolor="$*page_back" text="$*entry_text" link="$*page_link" vlink="$*page_vlink" alink="$*page_alink"> """;
$this->print_control_strip();
"""
<div align="center">
Should you wish to add extra HTML or CSS that would appear if the Navigation Strip is displayed, you can use the function viewer_sees_control_strip(), like this:
if (viewer_sees_control_strip()) {
"""Extra HTML or CSS to display, if the navigation strip is displayed""";
}
You will also need to enable the Navigation Strip in the Customize Journal Style page before it will appear on your journal.
