Saved webpage javascript don't work locally? -

i found site testing knowledge on html elements timed test( http://thehtml5quiz.com/ ). want save page , work locally, can alter test suit studying needs.

when save page, , open in browser, goes directly test being finished , never chance take test.

im still studying css , haven't made javascript yet.

i appreciate on getting going, me learn faster if create own memorization tests.

thanks lot.

you need save page 'webpage, complete'. should give supporting files in sub directory
