How do you change size of h1, h2, h3

[carriejordan]

How do you change sizes of header fonts without CSS? You used to be able to do this in customizer. Seems like everything is changed in CSS now.
Please advise.
I want to make all Header (H1, H2, H3) smaller proportionally. therisecollective.org.
Thanks for your help.

Hey There,

Currently, there is only way is using the custom CSS:

h1, .h1 {
    font-size:30px;
}
h2, .h2 {
   font-size:25px;
}
h3, .h3 {
   font-size:25px;
}

Just note that, by using the CSS codes given here, you understand that you are setting a fixed value to your headlines thus making them non-responsive. Further custom development is required to achieve that and we could not continue on providing that because that is outside the scope of our support. Please see our Terms.

X does not have specific font size options for the different levels of headlines. It has predesigned percentage based sizes.

Because it uses a percentage unit, you can make it bigger or smaller by setting the Root Font Size in Theme Options > Typography. As you will see in there, the Root Font Size has a responsive setting (Stepped or Scaling). Once you’ve set it, all regular text in the theme including text in the Classic elements will be responsive while retaining symmetry.

Thanks.
