Font became bigger on iphone 5 and 5s

[marioaprea]

I tested liquid slider on iphone and i see that on a responsive web, the font became too much bigger when i view sites on iphone 5 and 5s. Why?

you can see here a simple test:

if you look the same page from a browser, it works well

Thank you

I cant load your page for some reason but I don't see how the font would be affected unless theres an unwanted style in there. Go through your CSS and check for anything that looks off.
