How to use media queries to implement responsive layout
With the rapid development of the mobile Internet, more and more users use mobile devices to browse the web. In order to adapt to devices of different screen sizes, responsive layout has become an important direction in web design. Media queries are one of the key technologies to achieve responsive layout. Through media queries, we can apply different styles according to the screen width or other characteristics of the device, so that the web page has a good visual and user experience on different devices.
Media queries can be defined in CSS using the @media
rule. Here is a simple example:
@media screen and (max-width: 600px) { /* 当屏幕宽度小于等于600px时应用的样式 */ body { background-color: lightblue; font-size: 14px; } }
The @media
rule in the above code specifies a media query with the conditions screen and (max-width: 600px)
, indicating that the style is applied when the device is a screen and the width is less than or equal to 600 pixels. Under this media query, we apply a different background color and font size to the body
element.
Through media queries, we can apply different styles according to different characteristics of the device. Commonly used features include:
- Screen width: You can use
width
,min-width
andmax-width
to specify the screen width. range. - Device type: You can use
screen
,print
andspeech
to specify different device types. - Device orientation: You can use
orientation
to specify the orientation of the device, such as landscape or portrait.
Here is a more complex example showing how to apply different styles based on different device characteristics:
/* 默认样式 */ body { background-color: white; font-size: 16px; } /* 小屏幕样式 */ @media screen and (max-width: 600px) { body { background-color: lightblue; font-size: 14px; } } /* 中等屏幕样式 */ @media screen and (min-width: 601px) and (max-width: 1024px) { body { background-color: lightyellow; font-size: 16px; } } /* 大屏幕样式 */ @media screen and (min-width: 1025px) { body { background-color: lightgreen; font-size: 18px; } }
Three @media## are defined in the above code # Query, corresponding to the styles of small screen, medium screen and large screen. This way we can apply different background colors and font sizes based on the device's screen width.
