Is it possible using CSS3 media queries to ask:
'is the height of the viewport larger than the width'?
or:
'is the width of the viewport larger than the height'?
I would like my images to be fluid in both directions!
Thanks.
For this you might use the following media queries:
orientation:portrait
orientation:landscape
I cannot give you more information on the media queries, as I haven't researched them yet. Do make sure they are supported by the devices you wish to support.
As for CSS: no, you cannot detect the width and height of your viewport using CSS. CSS is not a programming language, but a styling language. Unless you're using a CSS preprocessor (Sass, Less), you won't be able to do anything intelligent with it.
