html - 特定设备的媒体查询是什么？

Question

我正在研究响应式设计，但没有得到正确的解决方案。我需要为这些设备编写媒体查询，分辨率如下。

240*320,

240*480,

320*480,

480*800,

480*856

到目前为止，我已经尝试过这些媒体查询，但它们存在冲突

 @media only screen and (max-width:240px) { /* cover 240px portrait */}

 @media only screen and (min-width:320px) and (orientation : landscape) {/* cover 320px landscape for 240*320 */}

 @media only screen and (min-width : 479px) and (orientation : landscape) {/* cover 480px landscape */}

 @media only screen and (min-width : 480px) and (orientation:portrait) {/* cover 480px portrait */}

Answer 1

以下是标准设备的媒体查询。您可以在定义的媒体中分别编写全局样式和设备特定样式。

/* Smartphones (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 320px) 
and (max-device-width : 480px) {
/* Styles */
}

/* Smartphones (landscape) ----------- */
@media only screen 
and (min-width : 321px) {
/* Styles */
}

/* Smartphones (portrait) ----------- */
@media only screen 
and (max-width : 320px) {
/* Styles */
}

/* iPads (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) {
/* Styles */
}

/* iPads (landscape) ----------- */
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape) {
/* Styles */
}

/* iPads (portrait) ----------- */
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) {
/* Styles */
}

/* Desktops and laptops ----------- */
@media only screen 
and (min-width : 1224px) {
/* Styles */
}

/* Large screens ----------- */
@media only screen 
and (min-width : 1824px) {
/* Styles */
}

/* iPhone 4 ----------- */
@media
only screen and (-webkit-min-device-pixel-ratio : 1.5),
only screen and (min-device-pixel-ratio : 1.5) {
/* Styles */
}
