In this case, IF a browser is non-supporting it will fallback to the second Style-sheet ignoring the first.In the past, building a website was much simpler. If we don't use "only" it will still work as desktop-style will also be used striking android styles but with unnecessary overhead. Want to add in here that the purpose is simply to prevent non supporting browsers to use that Other device style as if it starts from "screen" without it will take it for a screen whereas if it starts from "only" style will be ignored.Īnswering to ashitaka consider this example ![]() We shouldn't use the only keyword in that context, right? " The answer by is quite informative, except it doesn't explain the purpose as mentioned by "What if you use the Mobile First approach? So, we have the mobile CSS first and then use min-width to target larger sites. It would be a good test for someone with access to a device lab. To make sure it is not interpreted as media="screen" I'm not entirely sure which browsers that don't support CSS3 media queries would need the only version media="only screen and (min-width: 401px)"Īs opposed to media="screen and (min-width: 401px)" They will, however, still be downloaded.Īlso, in browsers that support CSS3 media queries, both versions will load the styles if the viewport width is larger than 401px and the media type is screen. Will have the same effect in IE6-8: both will prevent those styles from being used. So, using media="only screen and (min-width: 401px)"Īnd media="screen and (min-width: 401px)" In spite of this behavior, it's still recommended to prefix media queries with only if you want to hide the styles from other, less common browsers. Instead of applying the styles to all screen devices, it ignores the style sheet altogether. Unfortunately, IE 6–8 failed to implement the specification correctly. In other words, it should apply the style rules to all screen devices, even though it doesn't know what the media queries mean. Similarly, an old browser should interpret media="screen and (min-width: 401px) and (max-width: 600px)" So, an old browser should interpret the preceding example as this: media="only"īecause there is no such media type as only, the stylesheet is ignored. For example: media="only screen and (min-width: 401px) and (max-width: 600px)"īrowsers that don't recognize media queries expect a comma-separated list of media types, and the specification says they should truncate each value immediately before the first nonalphanumeric character that isn't a hyphen. Like not, the keyword must come at the beginning of the declaration. The media queries specification also provides the keyword only, which is intended to hide media queries from older browsers. Hopefully this sheds some light on media queries.īe sure to check out excellent answer on how the only keyword is really handled. Here's the link to that quote that is shown in example 9 on that page. ![]() User agents must process media queries starting with ‘only’ as if the ‘only’ keyword was not present.Īs there is no such media type as "only", the style sheet should be ignored by older browsers. The keyword ‘only’ can also be used to hide style sheets from older user agents. Here is a quote straight from W3C to explain this one. This is almost identical to the above except you are specifying screen as opposed to the other available media types the most common other one being print. This one is saying for a device with a screen and a window with max-width of 632px apply the style. At that size you would be talking about anything smaller than a desktop screen in most cases. This one is saying for a window with a max-width of 632px that you want to apply these styles. Let's break down your examples one by one.
