Twig Ternaire - CSS

Introduction

Twig ternaire is a powerful tool for writing more concise and expressive code in Twig templates. It allows you to write conditional statements with a single line of code, making your templates more readable and easier to maintain.

In combination with CSS, it can help you make your styling more dynamic and adaptive to different states and conditions.

In this article, we will explore how to use Twig ternaire to write conditional CSS in your templates.

Basic Syntax

Twig ternaire is based on the ternary operator, which consists of three parts:

1. The condition to be evaluated
2. The value to be returned if the condition is true
3. The value to be returned if the condition is false

The basic syntax of the ternary operator is as follows:

(condition) ? (value if true) : (value if false)

Conditional CSS using Twig Ternaire

To write conditional CSS using Twig ternaire, you can use the following syntax:

.selector {
  property: (condition) ? (value if true) : (value if false);
}

For example, if you want to set the background color of a button to red if it is disabled, and green if it is enabled, you can use the following code:

<button {% if disabled %} disabled{% endif %} class="my-btn" style="background-color: {{ disabled ? 'red' : 'green' }};">
  {{ label }}
</button>

In this code, we use the Twig ternaire operator to set the background color of the button based on its disabled state. If the button is disabled, the background color will be set to red, otherwise it will be set to green.

Conclusion

Twig ternaire is a simple and powerful tool for writing more concise and expressive Twig templates. It can also be used to write conditional CSS, making your styling more dynamic and adaptive to different states and conditions.

By using Twig ternaire with CSS, you can write cleaner and more readable code, while also making your templates more maintainable and easier to work with.
