media-queries

问题 I need a quick and dirty way to detect media query support using jquery. I defined a function as follows: function mediaQueriesEnabled () { var v = parseFloat($.browser.version); if ($.browser.msie) { if (v < 9) return (false); } return (true); } Can someone help me fix this up a bit? Looking at this page: http://caniuse.com/css-mediaqueries I realized that there are some complexities here. For example, when I test my version of safari, I get "534.57.2". I want to avoid installing modernizr

问题 By default I want to give my body element a green border. On a device that supports retina display I want to check for size first. On an ipad I want to give my body a red border and on an iphone I want to give it a blue border. But nesting media queries like so doesn't work: body { border: 1px solid green; } @media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) { @media (max-width: 768px) and (min-width: 320px) { body { border: 1px solid red; } } @media (max-width: 320px) {

问题 I have my site HEAVILY modified via @media queries to display very slimdown'd on mobile phones. However, my users are asking for the desktop version of the site (available via a link). To go a step further, the desktop site itself also gets modified by @media queries depending on resolution. I was thinking of picking one 'desktop' resolution, say 1440x900 and forcing the mobile phone to display at that resolution? Is this possible, maybe through JavaScript? Alternatively, can these @media

问题 I have multiple media queries running, however it is only using the largest query as opposed to the one that is correct. See codepen here: http://codepen.io/Not_A_Fax_Machine/pen/wdyjWO @media (max-height: 346px) { li.sidebar-list { max-height: 69px !important; } } @media (max-height: 480px) { li.sidebar-list { max-height: 96px !important; } } 回答1: CSS media query stacking should be done from the biggest width down to the lowest width. This is what CSS stands for - cascading style sheets .

问题 I'm trying to work out how to use EM media queries in my latest project. However after some testing I've found that the media queries are ever so slightly off and I can't work out why. It might have something to do with it using the parents font size instead of the body. My body is set to 14px and my workings out look like: $break-small: 22.8571em; //320px $break-smallish: 40em; //560px $break-med: 54.8571em; //768px $break-medish: 68.5714em; //960px $break-desk: 73.1428em; //1024px body font

问题 I have this code in my first CSS file: /* min-width */ @media (min-width: 768px) { .navbar-static-top { border-radius: 0; } } /* max-width */ @media (max-width: 767px) { .navbar-form .form-group { margin-bottom: 5px; } .navbar-form .form-group:last-child { margin-bottom: 0; } } I have this code in a CSS file linked after the first file: /* min-width */ @media (min-width: 992px) { .navbar-static-top { border-radius: 0; } } /* max-width */ @media (max-width: 991px) { .navbar-form .form-group {
