Hi, I am bit confused as never done mobile website.

I was thinking we have to use jquery to create a website into mobile.

is it possible we can use only php/mysql and html?

Is it mean that mobile website is smaller version or is it mean we have to use some certain technologies like jquery, html5.

How google/other search engines will know this is mobile version and other is general website for computers.

I was thinking differently but today i donwload free version of mobile website and in coding they only used html css? what about php can we use it too without jquery for database.

sorry to ask realy basic question. I am trying to create a first mobile website.

any advice / hints will be much appreciated.
