Will using lengthy CSS custom property names impact the performance of a website?

I've been contemplating experimenting with projects that aim to shorten CSS variables in order to decrease the size of my CSS file.

How do long CSS custom property names impact page performance?

  1. Reduction in CSS file size (including compression)
  2. Impact on CSS parsing and evaluation

Answer №1

Using longer variable names in your code will not have a significant impact on performance, especially when it comes to CSS parsing and rendering. Even with server compression tools like gZip, the amount of data transferred from the site to the user is not greatly affected by longer variable names. Instead of worrying about variable name length, focus on optimizing other aspects of your site to improve overall performance.
