Hyphens vs. Underscores in CSS: Which to Use?
An example of an AI chatbot conversation about hyphens and underscores in CSS naming conventions.
What's the difference between using hyphens and underscores in CSS class names?
In CSS, hyphens are commonly used in class names (e.g., .my-class-name) because they are more readable and align with CSS conventions. Underscores (e.g., .my_class_name) are less common and can lead to confusion with other programming languages.
Are there any performance differences between the two?
No, there are no performance differences between using hyphens and underscores in CSS. The choice is mainly about readability and consistency.
Which one is more widely accepted in the industry?
Hyphens are generally more widely accepted in the industry for CSS class names. They are the standard convention in most CSS frameworks.
Can I mix them in my project?
It's best to stick to one convention throughout your project for consistency. Mixing them can lead to confusion.
