Since I personally despise the paper, I really wanted to criticise The Daily Mail’s website. But unfortunately for me, it’s actually very good.
It uses XHTML 1.0 Transitional and the layout is CSS-controlled (no tables). While a better use of colour could be made to increase separation between content areas, and the links probably should be underlined, it’s generally hard to fault.
It doesn’t validate, unfortunately. In fact, the home page alone has 884 errors, although they’re probably the domino effect of a few small errors. Still, it’s nice to see that even the Mail can have a forward-thinking website.
