Dear Dave,
thank you for noticing this, and my apologies for the bug! Indeed, on smaller screens long page headings get cropped on the right; to fix this, please go to “Appearance -> Editor” and inside the file that opens (style.css) locate (ctrl+f) the line which says:
.page h1 {
float: left;
width: 100%;
}
It should be number 606; erase the part which says “width: 100%;” and hit “Update file”.
I must note that I was not able to reproduce the same bug on a normal-sized laptop screen, could you please provide the URL of the page in question so that I could look at the code?
Sincerely,
Andrew | Satori Studio
