&#x27;Mini&#x27; a totally different beast to a normal browser, in order to minimise data usage.<p>When you request a page in opera mini, that request is sent to Opera&#x27;s servers. The webpage is rendered on their server [using their rendering engine], and a totally different (OBML) file is sent to your browser, to represent the end result.<p>&#x27;Mini&#x27; never sees HTML, Javascript or CSS -- those are handled on the server. This allows the browser to use dramatically less bandwidth... but creates some major limitations.<p>Opera still makes &#x27;normal&#x27; browsers -- and at least in the iOS version, the &#x27;Mini&#x27; mode can be switched off [making it render the same as any webkit browser.]
