The document discusses conventions of website design. It notes that logos are typically placed in the upper left corner but some TV websites break this by centering their logo. Main navigation bars are usually at the top but ITV places theirs below images; non-standard placement can confuse users. Links are typically underlined text or differently colored text to indicate interactivity; avoiding underlining non-links and using color inconsistently causes confusion. Buttons should link to other pages or areas; non-functional buttons frustrate users.
