Some commonly used browser CSS compatible writing methods

In front-end development, especially when writing CSS, we must take into account the compatibility issues of various browsers. Different browsers parse CSS differently, which means different styles may appear in different browsers.

In order to solve this problem, we need to adopt some compatibility writing methods to ensure that the page can be displayed normally in various browsers. Below, this article will introduce some commonly used browser CSS compatible writing methods.

1. Box model

The box model is the basis of CSS, but in different browsers, there may be differences in the parsing of the box model. Especially in the two browsers IE6 and IE7, the box model is parsed differently from modern browsers.

To solve this problem, we can use the box-sizing attribute, which allows us to specify how the box model is parsed.

For example:

div{
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing : border-box;
}

In this example, we parse the box model to the entire element size including padding and border by setting the box-sizing property to border-box. Then make sure this property works correctly in all browsers by adding a prefix before each browser.

2. Gradient background

Gradient background is a commonly used effect in modern web design, but in different browsers, the way to parse the gradient background will also exist. difference. To solve this problem, we can use CSS3 gradient syntax and then add the -Vendor prefix to ensure that it works correctly in all browsers.

For example:

background: -webkit-linear-gradient(#000, #fff);
background: -moz-linear-gradient(#000, #fff);
background: -ms-linear-gradient(#000, #fff);
background: -o-linear-gradient(#000, #fff);
background: linear-gradient(#000, # fff);

In this example, we define a gradient color background, and then by adding the -Vendor prefix, it can be displayed normally in all browsers.

3. Text Shadow

CSS3 text shadow effect is also very common in modern web design. However, in some older browsers, this effect may not be supported. To solve this problem, we also need to use the -Vendor prefix to ensure that this effect works correctly in all browsers.

For example:

text-shadow: 1px 1px 1px #000;
-webkit-text-shadow: 1px 1px 1px #000;
-moz-text-shadow: 1px 1px 1px #000;
-ms-text-shadow: 1px 1px 1px #000;
-o-text-shadow: 1px 1px 1px #000;

In this example, we Define a text shadow effect and add the -Vendor prefix so that this effect can be displayed normally in all browsers.

4. Rounded border

The rounded border of an element is also a commonly used effect in modern web design. However, in old browsers, this effect may not be supported. . To solve this problem, we can use the CSS3 border rounded property and then use the -Vendor prefix to ensure that the effect works correctly in all browsers.

For example:

border-radius: 10px;
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
-ms- border-radius: 10px;
-o-border-radius: 10px;

In this example, we define a rounded border for an element and use the -Vendor prefix to Make sure this effect displays properly.

5. Media Query

Media query is an important feature in CSS3, which allows us to define different styles according to different screen sizes and device types. However, in older browsers, this feature may not be supported. To solve this problem, we need to use some special compatible writing methods so that media queries can work properly in old browsers.

For example:

@media screen and (max-width: 768px) {
/ styles for screens with width <= 768px /
}

@media only screen and (min-device-width: 320px) and (max-device-width: 480px) {
/ styles for iPhone and other similar devices /
}

In this example, we use media queries to define styles for different screen sizes, and then use the -Vendor prefix and the only keyword to be compatible with older browsers and specific device types.

Summary

When writing CSS, we need to fully consider browser compatibility to ensure that our pages can display properly in all browsers. This article introduces some commonly used browser CSS compatible writing methods, including box model, gradient background, text shadow, border rounded corners and media queries. By using these compatible writing methods, we can make our website work properly in various browsers and provide a better experience for our users.
