It also supports sizing panes in ems so you don't even have to calculate between pixels and ems! Aspect ratio If you think sizing in ems is hard because you don't know how large an em is: media queries are handled at the top level, so 1 em is always 16 pixels or what the browser set as the default font size (and so are rems).ĭid you know Polypane automatically detects the width and height media queries in a site and creates panes for them? That way, you're always building sites to your own specifications. This won't happen with pixels, and rem is the same size as an em when it's used in media queries. It's recommended to use the em unit for media queries, so it scales nicely when people zoom in their browser. More useful are the min-* and max-* values, which let you write CSS for screens starting at a certain size and larger (using min-*), or up to a certain size (using max-*).Īll the width and height media features support the regular CSS units like pixels and ems. Width and height you'll probably never want to use, they only apply at that exact width. You can check for exact width, min-width and max-width, and exact height, min-height and max-height. Dimensionsīy far the most used media features are related to browser dimensions. They let you check for device and browser capabilities, settings and user preferences beyond just the type of device. Media query feature make up the main part of a media query and have the most influence on what you're designing. embossed (like a combination of print and braille, so for printed braille).handheld (for phones, they were actually used for a while before media expressions were a thing),.Originally for use with speech synthesizers, like screen readers. So just for completeness, here's all the other ones that you never got to use, and probably never will: Probably what you're reading this article on now! Printįor when you print a page, or any "paged" media (Like a book! Did you know people use HTML and CSS to mark up books?)ĭid you know you can easily switch between screen and print stylesheets in Polypane with our emulation features? There used to be loads, but the level 4 specification deprecated a whole lot that were never implemented anyway, leaving us with 3 we should care about:Īs mentioned earlier, if you don't specify a media type, it will default to "all", which means the css will apply to all devices. The media type is used to describe the type of device that a browser is running on.
