I know HTML5 is not complete and cannot be used for websites that will be viewed with old browsers but can we start adapting some of the naming conventions to name our main div containers like header, nav, section, article, footer etc. so when the time comes you will already have all these name tags habits.
Are you currently doing something like I described above when naming your divs for your new designs?
Are you using HTML5 in your new design? If yes, can you name some of the features you are using?
Is it ok to use the new HTML5 Doctype? If yes will this work in older browsers?
