[NFBCS] Low-cost Accessible Website

[Greg Kearney]

CSS, short for Cascading Style Sheets, is a method of controlling the visual appearance of a web page while leaving the structure of the page untouched.

For example with CSS you can control the size, font, colour, alignment and so on of an H1 heading tag without having to call any HTML to the tag itself.

From an accessibility point of view this is good as screen readers want to interact with the page structure and not visual appearance. For page maintenance it is handy because you can make changes page or even site wide by only changing the CSS in one place and then those changes will propagate across the site with no further editing.

CSS can be included in any HTML tag using the style attribute, it can be placed at the head of the HTML file in a style tag or it can be included into a HTML file from a separate CSS document. It is possible to have different CSS stylesheets for different situations such as for computer, mobile devices, when a page is printed and even in theory for users of assistive technology.

You should use CSS to control the visual layout of the page.
