media-queries

问题 @media query is not working in case of iPhone 5 and iPad 4 OS . I have used following CSS for styling each OS and device for different screen. I explicitly checked that my iPad and iPhone width and height and based on that only i have kept the media queries. This works fine on ANDROID OS. /*@media print {*/ /* iPhone 5 (Portrait) */ @media screen and (max-device-height: 568px) and (orientation: portrait) { #map_canvas { border: 1px dashed #C0C0C0; width: 290px; height: 473px; } } /* iPad 4

问题 Is this: @media all and (min-width: @medium-min) { } The same as this?: @media (min-width: @medium-min) { } I cant see why adding 'all' would make any difference than not specifying. However I often see the 'all' has been added. Is there an edge case that requires this? 回答1: Yes it does and by default it's set to all. All devices listen to this Available media types: all: All devices listen to this braille: Used for braille tactile feedback devices. embossed Used for paged braille printers.

Is this the case? 回答1: You can use device-width which will test of the screen's width in px. That however is not entirely recommended. Use max-width and min-width (for the viewport) instead. If you are trying to GET the screen width and use it (something like content: (device-width); of some sort,

问题 I'm using css media queries on my website to switch to a more vertical layout on smaller devices. This works quite well, but I'd like to add a button on the site with something like "Show desktop version". I want to make this button (or link, whatever) force or alter the media query evaluations so they evaluate as if the screen width was bigger than it is (e.g. 1200px instead of 320px). Is this possible? My css looks like this: #logo { /* Mobile style */ [...] @media (min-width: @screen-sm) {

问题 It seems to me that it is infinitely better to define media queries in the HTML file within the link> tag rather than by using @media only... in external CSS files. You can have a large number of specific files modularized quite nicely and extremely specifically depending on what device is being targeted, and only the files you need will be retrieved. I can't think of a single reason not to use this method, or a single instance where it would not be superior. And yet, I've been unable to

问题 I'm trying to make a website that is essentially a few vertically positioned slides. I had been hoping to make a responsive design so my "slides" are appropriately resized on larger screen sizes or are padded appropriately in strange dimensions. Here is my LESS file setting the appropriate dimensions: html, body { width: 100%; height: 100%; padding: 0; margin: 0; } //============================================================ // Dimensions for each section for standard desktop screen //=====
