Inconsistent font size and text color on mobile version

[helloworld11]

I spent a ridiculous amount of time trying to get consistent font size and text color on the mobile version, and website as a whole.

I've tried on the editor and in the theme section.

Is there another way to edit text on the mobile version?

The text should automatically resize, but if you edit the backed code it may cause some issues. It also looks like your site was created through a third party host so Weebly reps are unable to log into the account to confirm. I recommend changing the theme back to a standard theme, and then checking the site. You may need to reach out to your host directly for assistance since we have very limited access to your account.
