I found the following line of code inside Wordpress' Twenty Eleven theme stylesheet.
What does it mean?
@media only screen and (min-device-width: 320px) and (max-device-width: 480px)
@media only screen This means we will apply css styles to a device with a screen. The keyword only used here to hide style sheets from older browsers from seeing phone style sheet. and (min-device-width: 320px) and (max-device-width: 480px)
@media (min-width: 576px) and (max-width: 768px) { ... } Above CSS will be applied to only those screens whose width is greater than 576px and less than 768px. // Small devices (landscape phones, 576px and up) @media (min-width: 576px) { ...
Above examples states that the specified block of media CSS will be applied only when the device width exceeds 576px or becomes equal to this. It means that above CSS will be applied whenever the application is opened in the larger devices. i.e. Tablet or Desktop. @media only screen and (max-width: 576px) {...}
This is quite obvious since it means that the specified css only applied when a device has a screen's size with minimum 320px and maximum of 480px in width dimension. Show activity on this post. The @media rule is used to define different style rules for different media types/devices.
It's called CSS3 Media Queries which is a technique to help your website adapt to various of screen dimensions or basically, it helps to deliver different styles to different devices.
Since you're new, let's break down your media query to two parts:
@media only screen
This means we will apply css styles to a device with a screen. The keyword only
used here to hide style sheets from older browsers from seeing phone style sheet.
and (min-device-width: 320px) and (max-device-width: 480px)
This is quite obvious since it means that the specified css only applied when a device has a screen's size with minimum 320px
and maximum of 480px
in width dimension.
