html - Is the holy grail still important or is that history? -

-

before html5, lot of effort made have main content in html source, before columns marked aside today. (the optimal way 3 column layouts holy grail).

there 2 reasons this:

  • seo: earlier content counted more important search engines
  • accessibility: show important content first view content without css

with html5, can solve problem markup. can markup column on left aside , main content main. dump holy grail, use table-cell css effect of 3 equally high columns , html5 markup tell search engines/screen readers part main content is.

is holy grail still important seo/accessibility or history? important other reason?

most of time mobile seems answer. in mobile layouts, content order matters. adapt question:

is holy grail still state of art multi column layouts?

ps: know flexbox coming. i'm asking backwards compatibility in mind.
