hyphenate only mobile view

hi

How to hyphenate but just in mobile view of page?

Here is code I use for mobile view. I’m making a font a little bigger, justify is enabled and i would like also to hyphenate .entry-content class but just in mobile view:

@media (max-width: 768px) {

.entry-content {
font-size: 105%;
text-align: justify;
}

Of course if I replace class “hyphenate” in settings it works fine but globally for both views, desktop and mobile but I need just mobile. Can I add somehow hyphenate to above code?
