Using CSS only for Firefox
When developing a web application, developers must ensure that it displays properly in every browser. Some CSS properties are not supported in browsers like Firefox but are supported in other browsers like Chrome, Opera, etc.
In this case, we need to write CSS code that only targets the Firefox browser. In this tutorial, we'll learn two different ways to write CSS, just for the Firefox browser.
Use Mozila-specific CSS extensions
The first way on our list to use CSS for the Firefox browser is to use the '@-moz-document url-prefix()' CSS specific extension. We need to write the CSS code in this CSS extension so that it will only be applied to the web page when the Firefox browser is opened.
grammar
Users can use the @-moz-document url-prefix() CSS specific extension following the following syntax to use CSS against Firefox.
@-moz-document url-prefix() {
/* Add CSS here */
}
Example 1
In the example below, we create an HTML div element and add text content inside it. After that, we used @-moz-document url-prefix() in CSS to apply styles only to div elements in Firefox browser.
Users can open the following web page in Chrome and Firefox browsers and observe the differences in div element styles.
<html>
<head>
<style>
@-moz-document url-prefix() {
.firefox {
background: green;
border: 1px solid red;
padding: 20px;
margin: 20px;
font-size: 1.3rem;
color: white;
width: 500px;
}
}
</style>
</head>
<body>
<h3> Using the <i> @-moz-document url-prefix() CSS-specific extension </i> to target only Firefox browser </h3>
<div class = "firefox">
<p> Firefox is a free, open-source web browser from Mozilla. </p>
</div>
</body>
</html>
Example 2
In the example below, we create a parent div element and add some other div elements inside it. In CSS, we use @-moz-document url-prefix() CSS specific extension to style div elements only in Firefox browser.
In Chrome, users can view a blank web page because no dimensions are applied, whereas in Firefox, users can view styled HTML content.
<html>
<head>
<style>
@-moz-document url-prefix() {
.parent {
display: flex;
flex-direction: row;
justify-content: space-around;
align-items: center;
height: 200px;
width: 500px;
background-color: yellow;
}
.first,
.second,
.third { height: 100px; width: 100px; }
.first { background-color: red;}
.second {background-color: green;}
.third {background-color: blue;}
}
</style>
</head>
<body>
<h3> Using the <i> @-moz-document url-prefix() CSS-specific extension </i> to target only firefox browser </h3>
<div class = "parent">
<div class = "first"> </div>
<div class = "second"> </div>
<div class = "third"> </div>
</div>
</body>
</html>
Use @supports rules
CSS contains various rules, each providing different functionality. The @supports rule takes a condition as a parameter and if the condition becomes true, the CSS is applied to the web page in Firefox browser.
In our example, we will use the "-moz-appearance:none" CSS condition to check if the current browser is Firefox. ‘-moz-appearance:none’ removes the default style of HTML elements such as checkbox, but here, we can use it to check whether the current browser is Firefox.
grammar
Users can use the @supports CSS rule according to the following syntax to use CSS for the Firefox browser.
@supports(-moz-appearance:none) {
/* CSS code */
}
In the above syntax, we need to add CSS code in the declaration block of the @supports rule.
Example 3
In the following example, we have created three different "
elements in HTML. After that, we use @supports rule and "-moz-appearance:none" condition to set only in Firefox browser CSS for the "
" element.
In the Firefox browser, users can observe different colors of text.
<html>
<head>
<style>
@supports(-moz-appearance:none) {
p.one {color: red;}
p.two {color: green;}
p.three {color: blue;}
}
</style>
</head>
<body>
<h3> Using the <i> @supports CSS rule </i> to target only the firefox browser </h3>
<p class = "one"> TutorialsPoint </p>
<p class = "two"> CSS </p>
<p class = "three"> HTML </p>
</body>
</html>
Users learned to target the Firefox browser using only CSS. We used CSS specific extensions and @supports rules. Users should only use CSS against Firefox when the Firefox browser does not support certain CSS properties to apply alternative styles.
