这称为响应式Web开发(RWD)。
为了使页面响应所有设备,我们需要使用一些基本的基础,如: -
This is called Responsive Web Development(RWD). To make page responsive to all device we need to use some basic fundamental such as:-
1。在头部设置视口元标记:
<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1.0"/>
2.使用 media queries 。 / strong>
2.Use media queries.
示例: -
/* 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 */
}
3。或者,我们可以直接使用 RWD框架: -

4。大型装置,中型装置&小型设备媒体查询。
4. Larger Device, Medium Devices & Small Devices media queries. (Work in my Scenarios.)
在通用设备类型的媒体查询之下: - 更大的设备,小设备。
这只是基本的媒体类型,适用于所有的场景&容易处理代码而不是使用各种媒体查询只需要关心三种媒体类型。
Below media queries for generic Device type: - Larger Device, Medium Devices & Small Devices. This is just basic media types which work for all of scenario & easy to handle code instead of using various media queries just need to care of three media type.
/*###Desktops, big landscape tablets and laptops(Large, Extra large)####*/
@media screen and (min-width: 1024px){
/*Style*/
}
/*###Tablet(medium)###*/
@media screen and (min-width : 768px) and (max-width : 1023px){
/*Style*/
}
/*### Smartphones (portrait and landscape)(small)### */
@media screen and (min-width : 0px) and (max-width : 767px){
/*Style*/
}
