Font-size is very small in FitText.js

Question

when I first open my page, my h1 element's font-size shows very small. When I resize it, it automatically becoming huge. I want to know what is the problem with my code?

$('h1').fitText(0.273);

I didn't write font-size property in h1's css code. Thanks!

as i see fittext make it scalable. so you make 18/4*(browser scale). In sample with 0.273 font size is 220px, your font size about 18px
try to set
$('h1').fitText(1);
