Change default font on all elements

Hey,

I`m trying to change the default font (to an Hebrew one – Alef Hebrew) on all elements, but without success.

I tried to added the following code to the quick css form on the style tab:

@import url(https://fonts.googleapis.com/earlyaccess/alefhebrew.css);

<p>body, h1, h2, h3, h4, h5, h6, tr.pricing-row td, #top .portfolio-title, .callout .content-area, .avia-big-box .avia-innerbox<br />

{font-family: "Alef Hebrew", “Helvetica Neue”, Helvetica, Arial, sans-serif;}
