Astralsound Menus and Site Structure

Our site structure, menus and internal links have gone through a number of revisions since the Astralsound website was launched in 2001.

The main navigation tool is a single expandable (drop-down) menu at the top of every page, allowing direct access from any open page to any other page. If you cannot see or access the expandable menu, see Enabling Javascript, below

The Main Menu

In standard browsers using their default settings on most full-sized displays (800 × 600 or greater), the Navigation Bar at the top of each page provides links to the main website sections.

Section Heads are denoted by a down-arrow on the Navigation Bar. Each section menu expands on mouse-over to show the relevant sub-menu.

A Right-Arrow on a sub-menu item indicates that the page has its own subsection(s).

Positioning your cursor over any Navigation Bar or Sub-Menu button Highlights that button by darkening the background-colour, and clicking on a highlighted button, whether or not a subsection menu is also open, takes you to the to the page indicated. Button text corresponds closely - in many cases exactly - with a page's subject and/or title.

The Breadcrumb Menu

Immediately below the Navigation Bar is the Breadcrumb Menu, accessible on all devices and in all browsers. This shows Parent ► Current Page ► Child-1 - Child-2 - ... - Child-n, with links underlined.

The Search Facility

A Search box at the top of each page acts as a local search engine: when you press the Search button it returns all pages in the Astralsound website containing the words you have entered, in order of relevance. Searches can be refined on the Results page, allowing Boolean AND and OR functions, and exact phrase matching (the default function for multiple terms is AND). The search facility can also be accessed on the Search page.

Content-Based Links

On many pages there are links within the text to other pages (or to bookmarks on the same page). Links and pop-up tips (for example, definitions of technical terms) are indicated by underlined text and font colour. Links should also be apparent when you pass your cursor over them, although your operating system, browser, and system/browser settings will determine how they become apparent. By default, all links open in the current browser window.

We regularly check all internal and external links to make sure they work and lead to relevant pages. Although we cannot accept responsibility for the content of other sites, we don't want to link to any pages that are immoral, illegal, offensive, or even - using euphemism to avoid unwanted traffic - decorative rather than informative. If a link takes you somewhere you didn't mean to go (whether or not it is decorative), or doesn't function as it should, please let us know.

The Footer Menu

At the bottom of each page is a link to the top of that page, and beneath this are links to the head pages of each main section.

Enabling Javascript

The main navigation menu cannot be accessed or used in browsers or operating systems that do not support JavaScript, or in which JavaScript has been disabled. It is also intentionally excluded from small-screen devices (including many mobile phones, particularly if the screen is in Portrait orientation), for which the breadcrumb and page-footer menus are the only navigation methods currently available.

In most standard browsers (including Firefox, Google Chrome, Internet Explorer, Opera and Safari), JavaScript is enabled by default, but can be disabled by any user, and by various add-ins. If you are using any of these browsers and the Navigation Menu is not available, check that JavaScript is enabled in the following locations:

Menu display and function has been checked in all the above browsers. If you are using one of these and JavaScript is enabled but you still don't have the menu, check to see whether a browser add-on or plug-in has been installed that may prevent the menu from displaying.

If you cannot get the main menu to display or function, or if you are finding navigation of the site difficult for any other reason but have managed to find this page anyway, please let us know (and preferably also tell us which operating system and browser - with version/release numbers - you are/were using).
