@media only screen and (min-width: 300px) and (max-width: 767px) { .site-title { font-size: 80%; } /* Styles in this block are only applied if the screen size is atleast 300px wide, but no more than 767px */ } @media only screen and (min-width: 768px) and (max-width: 1023px) { .site-title { font-size: 90%; } /* Styles in this block are only applied if the screen size is atleast 768px wide, but no more than 1023px */ } @media only screen and (min-width: 1024px) { .site-title { font-size: 120%; } /* Styles in this block are only applied if the screen size is over 1024px wide. */ }
