Hi,
Thank you for your question.
I’ve seen your site and site header image. You are using text in the header image so when you view the small devices then the image text not showing properly.
Header image width set 100% so create the problem.
You should use the site title as a header title. Please set the header image without text and using text from the site title, it will be better for all devices.
If you want to use the image then you can use the CSS code. Go customize-> additional CSS and paste the CSS code.
@media (max-width: 767px) {
.xhimg-full img {
width: auto;
min-width: 460px;
}
}
Thanks again
