Hi there… I’m glad you like it. I will try to remember to update the tested WordPress version in the readme. But if it works there’s nothing else to really update.
The plugin doesn’t handle any styles… that’s all left to you. If you want to serve different styles to different devices you need to write what’s called a CSS media query.
As an example, the following sets the subtitle class size to .75rem. But then any device wider than 300px (so everything but mobile) will have a size of 1.5rem.
.subtitle {
font-size: .75rem;
}
@media (min-width: 300px) {
.subtitle {
font-size: 1.5rem;
}
}
You should be able to get pretty custom this way. You can read more about media queries in the documentation.
