Way to increase the font of redirection page

[Aris]

Hello.

After completing the sign-up, the user sees the of their registration in the inbox.
By clicking on this link, the following message opens for 5 seconds: "Your user account was succesfully activated. You'll be redirected in about 5 secs. If not, click here."
If this message appears on the desktop, the font is clearly visible.
However, when it appears on the screen of a mobile or tablet, it is very difficult to read.

The question:
Is there a way to increase the font and, perhaps, the formatting of this website?

Thank you.

Without seeing what you have done it difficult to help!. Are you using breakpoints? if so then you can apply a different font size so it will render correctly for different devices. If you need further help the please provide a "basic" demo not a url but a copy of your project ie the .wbs
