Checkpoint 4 Organize documents so they may be read without style sheets. When an HTML document is rendered without associated style sheets, it must still be possible to read the document.
Style sheets allow an element to be positioned anywhere in a window.
In fact, two paragraphs in an HTML document can be positioned such that the last paragraph preceeds the first one. This can create problems when style sheets are turned off, because the paragraphs will be displayed as they appear in the HTML document. The WAI example shows problems and solutions for this checkpoint. A text-only browser is helpful in making sure that pages follow this checkpoint. More information on this checkpoint is available from the WAI guidelines .
