Change font for only 1 page

How would I change the font only for one page and not the rest of the site?

 

Hello,

Through page id selector you can apply css style code only for specific pages.

Firstly go to the Pages > All Pages in your dashboard and hover the edit option of that page on which you want to change the font and copy its page-id number.

See the image for reference


Now, add that page id in the css code given below( current page id is 2)
after that paste the code given below in Custom CSS section
(Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard.

Code:

.page-id-2 h1, .page-id-2 h2,
.page-id-2 h3, .page-id-2 h4, .page-id-2 h5,
.page-id-2 h6, .page-id-2 a, .page-id-2 spam,
.page-id-2 p, .page-id-2 ul, .page-id-2 div{
font-family:symbol ! important;
} 

In place of "symbol" you can put your font.
This will solve your issue.
