Class Ternary Conditionals in CSS Sass

In this article, we’ll introduce how to use class ternary conditionals in Sass. Class ternary conditionals are a technique for conditionally switching classes in a stylesheet, allowing you to apply different classes based on different situations. This technique makes your styles more flexible and allows you to dynamically change the style of an element based on different conditions.

What is Sass?

Sass is a CSS preprocessor that extends the functionality of CSS and provides greater flexibility and reusability. Sass allows for variables, nesting, mixins, and other features within stylesheets, making them easier to write and maintain.

Using Class Ternary Conditionals in Sass

Class ternary conditionals allow you to dynamically toggle classes based on a condition. In Sass, we can implement class ternary conditionals using the @if statement. The @if statement determines whether to apply a specific class based on a given condition.

Here’s an example demonstrating how to use class ternary conditions in Sass:

$color: blue;

.btn {
background-color: $color;

@if $color == blue {
color: white;
} @else if $color == red {
color: black;
} @else {
color: gray;
}
}

In the example above, we define a variable, $color, and apply different styles to the .btn class based on its value. If $color is equal to blue, the text color is white; if $color is equal to red, the text color is black; otherwise, the text color is gray.

Application Scenarios for Ternary-like Conditionals

Ternary-like conditions are useful in many scenarios. Here are some common ones:

1. Dynamically Applying Styles Based on User Permissions

Suppose we are developing an administrative system and want to apply different styles to buttons based on user permissions. Using ternary-like conditions, we can dynamically switch the button style based on the user’s permissions, so that administrators and regular users see different button styles.

2. Applying Different Styles Based on Device Type

Sometimes we want to apply different styles to different devices. For example, we might use a simpler and more compact style on mobile devices and a more complex and detailed style on desktop devices. Using ternary-like conditions, we can dynamically apply different styles based on the device type.

3. Switching Styles Based on Page Status

In certain page or interaction states, we may need to apply different styles. For example, after a form is successfully submitted, we may want to display a success message and change the form’s style. Using class ternary conditionals, we can dynamically apply different styles based on the page state.

Summary

In this article, we introduced how to use class ternary conditionals in Sass. Class ternary conditionals can dynamically switch classes based on conditions and apply different styles based on the conditions. This technique is very useful for dynamically changing styles based on user permissions, device type, or page state. By using class ternary conditionals, we can more flexibly control and manage styles, making our stylesheets more maintainable and reusable. I hope this article helps you use class ternary conditionals in Sass!
