They are type of web navigation where current location within the website is indicated by a list of pages above the current page in the hierarchy, up to the main page.

AJAX stands for Asynchronous JavaScript and XML. It helps to use the abilities of JavaScript, the Document Object Model, and XML to create interactivity on the web. It is described as a collection of technologies used to automatically update and manipulate the information on a web page while it is being viewed in a browser (i.e. without the user having to manually refresh the page).

This allows developers to create more sophisticated web pages and applications without having to add to the native capabilities of the browser. A key component is the use of XMLHttp Request, a function originally added to browsers by Microsoft, to exchange data in the background with one or more web servers.


It enables equal access to online content and services for all people, including those with disabilities.

In practice, authoring an accessible website includes:

Fixed width layout

Fixed layouts are layouts that start with a specific size, determined by the Web designer. They remain that width, regardless of the size of the browser window viewing the page.

Designers prefer it with a print background, as they allow the designer to make minute adjustments to the layout and have them remain consistent across browsers and computers.


It is a programme that runs inside another application such as web browser. The programme starts when the page it is contained within is downloaded.

Applets are used to create features including news bars (tickers) or more sophisticated interfaces than those supported by the HTML standard.

In Hyper-G and possibly other hypertext systems, a backlink is a link back to the page or one of the pages that currently link to the page you're using.

Backlinks are already supported to some extent in the present Web system. Using JavaScript or a similar technique, you can add a button to your page that, when clicked, results in a request to the Alta Vista search engine to locate all the Web sites that link to your page (that is, to your home page backlinks)


A domain name is the textual identifier or an address for a website, for example:

Elastic layout

An elastic layout is a style of Web layout design that uses percentages for widths and a max-width style to ensure that the content should not be lengthy. Elastic widths stretch when font sizes are increased or decreased. This is what makes them elastic – they are flexible to accomodate the browser width and the reader's font preferences.
