Sliky theme missing doctype?

Hi, noticed than there isn’t doctype in Sliky theme’s HTML page

Tried to add it :wink: myself
then (on desktop view) frontend’s input fields aren’t displayed inline (as you can see on demo site)

Any idea? Many thnaks in advance

Best is probably to submit an issue to the original theme repository

Hi @ozh thanks to reply… you 're right :wink: but I’m not on Github then tried to take contact using his website form but without succes at this point
